Cardiologist’s scientific analysis of the Apple Watch

[@chubbyemu]

Excellent video! To me, medicine is characterized by a few things including 1) the notion of fear and the unknown and 2) excess and these are encapsulated in life-and-death. Those are distinctly different from tech, which for the most part is a nice to have but can live without it. This incompatibility amplifies the potential fear and this in itself create more excess. If Apple does not play its cards right, they could have just opened a giant can of worms. And the FDA won’t always be run by people who will allow this kind of thing.

[@MedlifeCrisis]

I've had a long standing interest in medical tech and have even done a tiny bit of consulting for an AI company. The disconnect between them and us is enormous sometimes. As you say medicine and technology come from very different starting points, even if we are respectively interested in the other field. I thought an analogy was Elon Musk's approach to the cave rescue. The Silicon Valley attitude is just to attack any conundrum in any way and deal with any problems as they arise. Like beta testing. They are now bringing that approach to medicine. Should be interesting!

I had to get rid of my Fitbit, it was enabling so much health anxiety it was actually making me ill. I have a family history of heart conditions, but I personally have no symptoms and have had medical tests to check for anything - all healthy. I am an active young person. However, just knowing about my family history was the tiny spark to check my Fitbit obsessively. I would check the data just to “catch anything early”. The anxiety was actually giving me palpitations and so made the anxiety worse. Sometimes too much access to information can be a bad thing, especially if like me you are prone to hypochondria.

[@lindalangve9039]

My Apple Watch kept alerting me multiple times to a low heart rate so I mentioned this to my NP. She did a 12 lead ecg and I was diagnosed with first degree AV block. She said I was the third patient she had whose watch alerted them to a condition that actually turned out to be a medical issue. I was referred to a Cardiologist who did further testing and discovered a leaky Mitral Valve. The bradycardia and the AV and the moderate mitral regurgitation will be monitored yearly and I spent a month on an event monitor because of some symptoms. So far so good. I am a 63 year old female and have a family history of heart disease and strokes. I don’t mind knowing that I have these issues and I don’t obsess on them. I focus on what I can do to stay healthy. The watch is one more tool that I can use to monitor my health and monitor my exercise.

I agree with you when it comes to the ECG. I have POTS and reflex neurocardiogenic syncope. And the heart rate monitor seems like a good thing in my case.

Subsequent to this video, it turns out that one of the main benefits of the Apple Watch is detecting V-Tach. - Ventricular Tachycardia, or rapid heart beat. There are quite a few people who were alerted by their Apple Watch that their rhythms were faster than 200 bpm. In MY case - I was the recipient of one as I had a STEMI in 2016. Having even a single-lead ECG with me at all times has been a RELIEF rather than a worry. Also, it detected a problem for ME, too. In January, my rate accelerated to 170 for no discernible reason. My normal rate ( with meds ) is 55-65. Turned-out that I had a bad reaction to some cold medications. I don't think that would constitute a false alarm....

I take 2 baby aspirin a day and when episodes happen I make sure to rest until I convert back to normal rhythm. I have a heart doctor and a family doctor that are aware, but I’m not on blood thinners, just aspirin maintenance, and my job is physical so I get exercise there. I have a yearly checkup, and I’m very healthy and the heart is healthy. I completely manage it on my own. Thank you for saving me $500!

I think you are exactly the person who doesn't need it, or wouldn't rely on it as you are under the care and advice of medical professionals. I think there is a big danger that people assume a monitor replaces medical supervision, a healthy lifestyle and management of symptoms.

[@popgunandy]

My Apple Watch alerted me to a racing heart rate on New Year's Day...it waiting 20-30 minutes before it sent me the alert. I was not feeling well but had no idea why. A blood pressure monitor I keep at home validated the information and identified super high BP. I went to the ER at the advice of a call-in nurse and they identified through an ECG an atrial flutter causing the problem. While waiting I performed one on my watch that matched their findings. They corrected the flutter with a drug, observed me for a while, and sent me home. My own doctor referred me to a cardiologist and he validated the findings but found no underlying problem following an echocardiogram and two-weeks on a monitor. I've had no symptoms since. Every professional I encountered was glad I went to the ER and it only happened because of the watch. Just fyi, I am a 54-year-old man with no underlying medical issue except arthritis. I appreciate the doctor's analysis, but I think it's smarter to simply put a watch's report in some sort of context rather than dismiss its value. When you have an adverse finding, there are steps to take before going nuclear with a diagnosis or rejection of the report.

[@Cin9999]

The casual humor + edits crack me up so much every time ^^ Its the perfect vehicle for these spicy science bits. You could give great lectures in University. Great work. Btw do you have any plans on making a video on diet and heart health? I feel like the media and the food industry have really muddied the waters to the point its almost a religious issue. There are people like Dr Kim Allan Williams, Dr. Caldwell Esselstyn who are really convinced their plant based diet-thing reverses atherosclerosis better than any drug etc. and on the other side people straight up deny that saturated fat and meat and stuff have any negative impact at all. I guess the AHA is somewhere in the middle but then again they are sponsored big time by (fast/) food companies and have a really strange divide in the conclusions of their research and the actual diet recommendations they give out. I would be quite interested in your perspective.

[@MedlifeCrisis]

Thanks! That's really nice to hear. Re: your question - short answer, yes I definitely do plan on it. But I have some reservations. 1 - I've seen colleagues get really hounded and trolled by opposing camps when they've voiced a fairly non-controversial position on something (in my opinion) like "keto has some problems" or "some fats ARE bad for you". 2 - it's such a minefield these days, it's very hard for a jobbing doctor like me to know what to believe, so the public must be drowning in misinformation. Many prominent academics, nutrition experts, doctors etc talk such BS it's hard to cut through. So if I do it, I really want to get it right and spend the time. I will - one day! A no-holds-barred take down of the religious (that's what they've become) diet extremists! Thanks again :)

[@Cin9999]

Very nice! I know what you mean by minefield - even as a med student I have seen the mudslinging that goes on. I knew a MD here in the UKE, Hamburg, Germany (big university hospital) that voiced his problems with the food patients get served. As soon as he was senior physician and became even more active with it, stuff went really crazy. I had never thought bullying like that would even be possible in academia today.

Another person might decide to go see a doctor after that has happened a few times, because he can put two and two together in his head, realize he's in a risk group. But not Tommy, because Tommy spent too many dollars on an Apple watch that told him everything was fine.

[@HarryEffieAnna]

I have had Afib/SVT 3 times - at 24,29, and 34 years old. I have been electro cardioverted for all 3 events. I have learned a lot over the past 10 years and the ECG function serves me well - despite being a youngish guy. I know people from ages 13 to 29 who have the ECG feature and have 0 (zero) logged ECG’s in their health app. They could care less about it. I think this feature is important to apples future since people between 35-45 years old are 1)still very interested in tech and 2)getting older. This is step 1 of what is to come in the world of medicine in regards to obtaining useful data. Any cardiac patient would know that not using a multi lead ecg machine will not generate hyper accurate data. But as you learn yourself - you may be able to notice patterns. For example, a change in position caused a short run of a-fib. It’s about knowing the data and not always acting on it. In your example - if a patient comes in one A-fib reading and you instruct them to relax and that it’s nothing... yet they still become hyper anxious? Thats the doctors responsibility. I often have to extract as much data as I can from my Cardiologists in order for me to feel comfortable. I doctors need to show more data or follow up with data to make their patients take something serious or to allow their patients to relax. Everything is data driven today - and i feel we need more data in this regards.

[@COddietsch]

Excellent information, liked your sense of humor. I have been told by ER Dr’s and my Cardiologist the same thing your saying. I supportively have a strong heart, owe thousands in testing now because I have palpitations and every once in a while my heart can’t figure out what to do so I go from a resting 60 to 160-170 bpm within a minute and sometimes it lasts for a few minutes. I go to the ER, get checked out and months later it happens again. So, unless I’m in pain or unconscious, I do my best to wait it out since I am also told that 160 bpm is where I should be working out, so even though it is discerning and uncomfortable..... DONT FREAK OUT. Ok! I was going to get an Apple Watch 4 because of this but I guess I’ll get one because it’s cool and it has other fitness apps.

I borrowed my mom’s Apple Watch this weekend because my heart was thumping hard in my chest. Did the ECG and it looked crazy. I passed out a few minutes later. Normally, I would have thought I was dehydrated or had low blood sugar etc. and not gone to the hospital. That day, I went instantly because the ECG scared me. I showed triage and they got me right into the back and hooked me up to a monitor. My heart rate was 178bpm by the time they tested me. I was admitted with atrial flutter, found out my heart was surrounded by fluid and one side was extremely enlarged. I had a cardioaversion done yesterday and I’m still in the hospital on meds. I will be sent home on dijoxon and cardizem tomorrow. I am only 30 years old and I almost had a stroke. As someone with no insurance, I’m reluctant to go to the hospital for anything and would have certainly been toast had I not borrowed the Apple Watch. Im not a doctor but I know what an abnormal ECG looks like from my own research and that was THE variable in getting me to the hospital.

[@theagilecoach2435]

I think this largely falls into his tennis-club analogy.. i.e. not really a medical/hospital issue; most athletes should just crack on and go for it according to whatever goals they have and training regime them and their coach buy into. The main issue from what I've seen is, do you take some time to stay in recovery zone if you detect heart strain, which is the new orthodox stance or is that precisely the time when pushing further might give you highest chance of adaptation to a new level, some epigenetic effect, make you start producing a new protein...

At 44 i sued to think like this and then i had a stroke. I've since been found to have had several strokes that were mis-diagnosed. I also have POTS, vasovagal syndrome, ehlers danloss syndrome, fibromyalgia, and several other related illneses. I need to keep eye on my heart rate as it often goes above 160 and stays there and then a valsalvo maneuvre i've been taught is required to bring it down. My life isn't fun but i'm still alive. I use an android watch as apple is a rip off. But it's important to me to do whatever i can to stay as healthy as possible. For people with pre-exisitng conditions that need monitoring i think there is room for this technology.

[@Kindness808]

I am interested in the implications of the HR capabilities of the Apple Watch. My father has Afib and has undergone 2 or 3 ablations. I've wondered if he had owned an Apple Watch if maybe he wouldn't have had to find out about this condition at the point that he needed 12 days in the hospital. Maybe it would have tipped him off to irregular activity. Thank you for your perspective on this. Helpful.

A very interesting analysis which shines a whole new light on something which I initially only thought could be of benefit in terms of AF diagnosis. Thanks :-)

Excellent points made! I've been involved with ECG/medical/nursing for the last 36 years! When I heard there was going to be an ECG monitoring capability on the Apple Watch, I thought the axact concerns as you stated. The general public is not well educated on the risks/benefits of any medical technologies, along with the risks for type I nor type II errors (as you allude to)! I will have my nursing students (and anyone else interested) watch this video as a matter of reference and education. Thanks for posting this!

[@mr_k4tz]

As a relatively young man (44) who had a stroke earlier this year, I really appreciate this video. The cause of the stroke was unknown but my doctor put me on Prednisone and 3 months of heart monitoring for suspected AF. After a month of daily migraines from the Prednisone, I had to convince my doctor that quality of life is something he might consider, he agreed to let me stop, albeit fairly reluctantly. I'm still taking statins and Asprin which have no noticeable side effects. In addition, My cardiologist wants to implant a heart bug. From the sound of your video, there would be little benefit to implanting the device in a youngish patient, especially since 3 months of monitoring revealed nothing. It makes me crazy how some doctors prescribe medication and procedures without considering the impact on patients' lives and mental health. It's nice to see a doctor who "gets it".

[@btonasse]

I fail to understand the similarities between what you describe what Rohin talks about in the video. His example hadn't had a stroke before going to the doctor. Of course you should always discuss alternatives with your physician, but second-guessing them based on a slightly related youtube video is a going a bit too far, don't you think?

[@grandcanyon6615]

I had an ablation procedure for my AF in 2008 for one side of my heart, then one in 2009 for the other. The Dr. is correct AF is nothing to mess around with. When you had it like I had it at aged 62 you can feel the skipping, the pauses, and the racing. It is extremely unsettling and downright scary. So, am I going to get the new Series 4, damn right I am.

David Richfield I totally agree. My educational background is mathematics & science (mostly physics) so I get the whole datum/data thing, but in my 35+ year career in IT (business), I rarely heard “data” being used as a plural noun. In fact, 98.6% of the English speaking world (guess which orifice that number was pulled from) uses (or should I say “use”) “data” as a singular noun.

“Data” should be treated as an uncountable noun

[@yanuchiuchihaanimegamesand3907]

Saitama?

[@kaitlyn__L]

Most people do in fact burn a majority of their calories just maintaining homeostasis.. so if it's showing total calories for the day that makes sense. The guideline of 2500 calories per day is given very mild activity, if you're doing more serious exercise you can easily go above 3000. Conversely if you live a sedentary life, you're still recommended 1500-2000 calories a day to maintain your body's systems. Assuming you've given it accurate data about your height and weight, and bearing in mind a roughly 10% range of accuracy on wrist-based heart rate monitors (eg I count 130 beats over a minute after jogging, the watch said 125-135 over that minute), then giving the calorie burn numbers similarly sized grains of salt, it should be reasonably accurate. The maths to work it out with omnipresent heart rate data is not that complicated. I don't know about Samsung but Fitbits will say total calorie burn over a day but also how many calories a specific period of exercise burned. On a low activity day it says about 2100 total for me, on a medium-to-high activity day it'll be between 2800 and 4000. The per activity breakdown is usually about 300-600 per activity. Which is still pretty small compared to the homeostasis cost. An extra 40-100% energy expenditure from a medium to big Actual Exercise Session? All that exertion and effort and breathlessness for multiple hours (over 10% of the day) only sometimes just about matches what the body does anyway; to stay warm, keep blood flowing, digest food. And the body can regulate how much energy it spends on homeostasis to a degree, that's why people with eating disorders so commonly feel freezing and tired all the time. The body noticed not many calories going in, and has turned down the body heat output to try and compensate a little. Conversely people who lift weights and eat properly will feel warmer all the time, the metabolic load increases due to maintaining many more muscle cells, which also generate heat from movement, which has to come from somewhere. It's the same reason that lifting weights without getting your macros means no gains - the body's energy prioritisation system says times are too "cash strapped" to invest in building new muscle "infrastructure".

[@tbirkley101]

I was diagnosed with AF 1yr ago after wearing a Zio patch 3 lead monitor prescribed by my cardiologist. I’m 39. Within a week I bought an Apple series 4 to help monitor it. The AF progressed rapidly. I would be in AF plus rapid heart rate at above 150+ beats a minute, while sitting, for 3+hrs at the max consistently. The Apple Watch seemed to mirror the tests, the EKG’s the ECHO’s while I took them. I took a reading frequently, the second I had a feeling of AF. I’m fit. I work out 5-6 days a week for 15yrs. I run, I lift, I do all kinds of different training. It’s as much a part of my life as sleeping. As the AF progressed I couldn’t do 1/2 what I used to. I used the Apple Watch to let me know at the gym if I was in AF or rapid heart rate and if I was, I stopped. I relayed all this information to my cardiologist, in phone calls when worried or at a scheduled appointment. 4mon after being diagnosed with AF I had an ablation surgery recommended by my cardiologist. That was 5mo ago. Now I have no AF. I’m back in the gym like I used to be. I’m down 20lbs. I feel like I used to. Now this is mainly due to my exceptional surgeon and the multiple EKG’s, ECG’s, Zio patch and other test they run. I do though feel the Apple Watch gave me the ability to monitor my heart when the doctors weren’t, in my everyday life, and allowed me to communicate what they saw. This helped convince them, I believe that my ablation procedure should happen sooner. Within 5mo of diagnosis I was operated on and 5mo after I feel great. For a year before I was miserable everyday. I barely check my heart on my watch anymore. It did though greatly effect my ability to get well quicker.

[@bingohhhhhhhhhhhh]

Just curious as it's been 4 years since your post - how are you doing now? Did the ablation take and you've had no further procedures?

[@kennethhumphrey952]

Maybe it's not something to run to the doctor about but at least it might prompt you that there might be a possible problem. Many times we go into the doctor without any information and they give us a good bill of health and they haven't done anything. There is nothing like spending a grand at the hospital and being told to take Advil.

[@builtontherockhomestead9390]

My EKG looked normal. A cardiologist didn't think I had a PFO. I was asking to be evaluated to see if I had a PFO due to migraines and other symptoms. Further tests revealed I did have a PFO, which was fixed. When doctors ask me about the surgery, mainly if it helped me I tell them oxygen is a wonderful thing.

(As you stated) More data is always better. If one is overly anxious about possibly inaccurate warnings of heart irregularity, the proper response is to control one’s anxiety, not to “kill the messenger,“ as it were. Wear the new Apple Watch, and if the “lo-res” EKG detects any irregularity, escalate to purchasing the more accurate band/phone combo, and give yourself even more data with which to make an informed decision. Thanks for the video, I appreciate it very much and thought it was great. In aggregate, across a large sample, maybe a low-quality EKG (such as the one in the Apple Watch) will do more harm than good, by creating worry or obsessive behavior, clogging the doctors’ office, or triggering some users to make uninformed assumptions. But if it is a commonly available technology that can give me any chance to avoid dying by escalating the monitoring of my heart (I.e. “if the Apple Watch detects something, move up to the next level of monitoring.“), … Then for me, it would certainly be a good thing. My opinion only, and I recognize and appreciate your much deeper understanding of this issue. Thanks again 🙂👍
