My daughter's apple smart watch helped in detecting my husband was in the middle of a heart attack. From what she saw, we went to the hospital & he got a stint. His symptoms were only sweating & nausea. No chest pain until well after getting to the ER. Thankful she was nearby with her watch & we were just a few blocks from the hospital.

[@yongnt]

Had a silent heart attack 2 weeks ago. My only symptom was sudden shortness of breath. I did use my Samsung Galaxy Watch4 to run an ECG on 7th Sep and another one on 11th Sep. Both tests were "inconclusive" and the waves were irregular but the watch prompted me to seek medical attention if the same results get repeated. So, I would believe that while these smartwatches do not explicitly check for heart attack (for one reason or another), they are smart enough to recognise a potential issue and alert you to take action about it.

[@DarkVeghetta]

Good to see doctors involving themselves in this ongoing conversation. Hopefully it will lead to more useful data to be collected in the long term and a better general awareness of what these measurements actually mean for one's health.

[@MidnightMarrow]

I have hashimotos and have had all kinds of autoimmune health issues the last few years, I wasn't feeling good at all at work one day, hand tremors, sweats, felt super weak etc, used the ECG on my watch and it said atrial fibrillation was detected, it subsided and I went in to the walk in to get it checked out when it started again showed the doc the watch's data and explained everything that happened then and what was currently happening at the time of going in and she sent me to the ER. The ER docs dismissed any of that info and even though my thyroid levels were good, talked about upping my dosage... So if I'm already having arrythmias and the like I don't see what compels them to want to up my dosage even though they even said the levels were good but of course this is hashimotos and as far as I know at any moment I could be flooded with thyroid hormone at any moment while still taking the daily doses of levothyroxine.

I have afib and a lot of pvc and pac. Will these watches pick up these abnormalities also? My Kardia does most of the time, but not always the most convenient to use.

[@WalturdTheCat]

Same for me, I wish someone would answer your question. After multiple heart monitors snd using Kardia app, I'm considering buying the Apple watch. But hate to spend the money if it wouldn't be accurate. I have SVT, PAC and PVC's. Recently, I was out without my Kardia device and believe I had an AFib episode.

[@HoldFastAndStoic]

I think it would be interesting if you watch could identify lethal arrhythmias such as ventricular tachycardia and ventricular fibrillation, contact 911 and give your location as well as your condition, sound an audible alarm and then flash on screen to start CPR. With the Apple Watch that is capable of making phone calls, if it automatically called 911, the operator could give instructions to someone who is not trained to do CPR.

[@crazybits9257]

How about the latest models? Fitbit has fb sense 2, theres also apple watch 8 and galaxy watch 5 now. I do have irregular heart rhythm and I do want something that's accurate. Which one do you recommend?

[@MickleDoc]

I couldn't find any published research that specifically mentions these devices. Its a big issue in the industry - knowing yesterday's model and algorithm are accurate is one thing, but what about newer versions? It's why the comparison study I reference is pretty big news in this space (albeit using older models). If you put a gun to my head though, I'd probably lean towards the Apple Watch 8. That's because looking at older models, Apple seem to have developed an accurate algorithm for detection of irregular heart rhythms that is always amongst the best. In addition to this, there are more journal publications on the use of Apple Watches for a variety of medical use cases that for the others. This doesn't neccessarily mean its better - but it means that if we discover more uses for this kind of technology, its more likely we'll find them for the Apple Watch before the others, if this trend continues.

[@crazybits9257]

@Mickle Doc Hey thanks so much for the reply! Really appreciate it. Awesome video too btw! Thanks for sharing your recommendation. I started following development updates for wearables with ecg 2 years ago when I found out I had some form of tachycardia... honestly was hoping to hear more praises towards the cheaper models as I'm not an iphone user (plus apple watch is more expensive than the rest) and the watch is unusable without an iphone. But yeah, at the back of my head, I do think joining the dark side might be a better investment health-wise. And I've been postponing this decision for way too long. Anyway, thanks so much for your insights! P.s. My cardiologist specifically recommended only the apple watch (q2 2021 so maybe series 5/6) and I kinda thought he was just an apple fanboy

[@ozugru]

@@crazybits9257 This is also the reason I'm considering an apple watch 8, even though I don't even have an iPhone. There is another youtube channel called the quantified scientist who uses real world data to compare health trackers (kzbin.info/www/bejne/j4fLnq2updxofck) and he also found that Apple watches are the most accurate.

[@timp102]

What an amazingly helpful video. My fitbit versa showed irregular heart rthym. My Dr confirmed this with an eg 24 hrs test. I had no symptoms so wouldn't have known I have atrial flutter.😮

[@scb2scb2]

And that is its real value. Having a device on with multiple uses like a watch that also keeps a eye on some vitals. It's not perfect but getting better but any 'hints' something is up is better than no hints at all. Over the last few years way more afib has been detected and people can act. The downsides is these more cases of detected afib are also being used in many conspiracies plots...

[@rbaxter286]

Actually JUST NOW, DURING THIS VIDEO pretty obviously re-locked into a sinus rhythm and came out of an afib episode, and both a Kardiacare and Garmin watch apparently verified the huge, off-the-cliff drop in heart beat rate which was also then backed up with the ekg results. Will still be going to my cardiologist appointment set up after I recognized the symptoms days ago, but the relief is amazing. I am perfectly happy with the diagnostic capabilities, but better is always appreciated. Now I can get back on my cycling training.

Hi Doc. Can you give me some advice. I have a fast heart rate even if Im in rest. My doctor also stops me from drinking coffee and everything that can cause palpitation.

[@susieroberts8175]

So Fitbit have reduced the False Positive rate but we don't know the False Negative rate? Doesn't sound like an investment to me ...!

[@scb2scb2]

You would rather have a false positive and test using the ECG function and when still in doubt goto the hospital to get a ecg than not detecting at all. Also not sure why he uses such old models even when making this video apple for example had already supported this for 3 years (first watch todo this was model 7 released a full 2 years before the video). For me apple watch 7 and new models have never detected a afib when it was not happening also in background mode. Detecting as a 'signal' so we can test is always 100% better than not knowing at all. Its like saying lets not put seatbelts on because some people still get killed.

[@traceystock7352]

Not a doctor here but a patient with lots of patient experience. Afib is very common and not necessaryily dangerous. If your total time in Afib is only a few minutes a year and when you have been drinking a lot of alcohol, you can just cut down on the drinking trigger mechanism and not worry. Also, a lot of aberrant readings on ECGs and smart devices tend to be captured as Afib. I once had a bad ECG reading in a doctor's office that said I had a Myocardial Infarction when I was highly fit and 38. There was nothing wrong with me.

It would be interesting if you could compare the Apple Watch ECG results with a Fitbit Charge 5 (or another Fitbit ECG enabled band) and a Kardia 6-lead device. To me, it doesn’t seem to make a difference which one you use, as they only look at the basic rhythm rather than analysing everything and taking a holistic view.

[@traceystock7352]

@@ml3141 I'm going through this right now. Options are: 1). Do nothing as Afib is not necessarily dangerous in and of itself but could be if you have other factors. 2). If you have a sustained Afib episode you can have it cardioverted to sinus rhythm either electrically or with a drug -- under medical supervision usually at an ER. This ends the episode but many times it returns (but not always). 3). You can take a rate control medication like a beta blocker if you Afib is the type with a high heart rate. And also take an anti-arrhythmic drug like digoxin or flecainide to reduce the arrythmia. These would be all the time. Drugs have side effects. 4). You could practice "pill in the pocket" strategy which is to take the prescribed rate control and anti-arrhythmic drugs as needed however this is a decision that mut be made in close consult with the medical team base don your risk factors and other drugs. 5). You can get an ablation that is an invasive but usually safe surgery where the doctor freezes or cuts the nerve on your heart that is sending the bothersome signals. Sometimes it works, sometimes it needs subsequent procedures. Of course risk is always present in procedures. 6). There is a new device called a Watchman that prevents clots that are the most dangerous possible effect of Afib. I am not a doctor but a new Afib patient and am considering options so just sharing.

I will do, thanks for the tip. I used to use a MyZone chest strap for heart rate monitoring too - it was consistently more accurate than my wrist-based wearables, so I tended to use it alongside my Smart Watch when exercising. Makes sense that the same principle would apply for ECG monitoring

[@skynineUK]

@@MickleDoc I've been using it for heart issues and it's a lifesaver and the people running it are also very helpful. The device will record a single source ECG (lead 5?) for up to 24 hours, it is synced to the cloud and the link can then be sent directly to the cardiologist. Real-time ECG's can also be monitored. The cost might seem high but it is less than the private cost of a 3 day Holter monitor. It is being sold as a fitness device but it's real benefit is for people like myself.

Good question. It's because independent research comparing wearables is rare!

That was great, Tom. Like many runners I wear a Garmin forerunner watch that has a heart rate monitor. That feeds into zones in Strava. My issue with that is it assumes a standard calculation to work out the maximum heart rate - 220 minus age. Based on that I should be dead, so as a keen athlete how can I work out what the correct heart rate zones should be?

[@MickleDoc]

Unfortunatley, there's no great solution to this. Several different formulas have been developed (the one you refer to is the Fox Formula, but there are others, like the Tanaka formula) but they all fall foul of over or under estimates. You might be best using a heart monitor (chest straps more accurate that wrist watches) and matching HR with your self-perceived exercise intensity, in order to map out your own, personalised heart rate zones.

Why use such old data? talking about the apple watch 6. The apple watch 7 and 8 where already released and also detected afib for example. My apple watch 7 picked up my afib during the day and started giving warnings >2.5 years ago. So it also supported the '24h detect mode'. I am not saying this video is not interesting but time has moved on we are close to the release of apple watch 10 already. Also while its true we have not seen how much/often it misses afib we do know its way way way more than not having any way to detect them 24h/day or even using the ECG if you feel weird. I always send my ecg to the hospital and they can work with this if anything new is happening they will call me in for the 'many wires one' to confirm a change. Its a great 'easy to have on' tool to keep track of things even if its not proof of anything at 100%. Its conclusion should be is it a 'confident hint' that can be used to talk to someone or go in for a test is a clear yes and thats is so much more than we had before.

I am a 66 year old who got an Apple Watch in 2020. It picked up and kept alerting me to a low heart rate. I used the ecg function to record my heart rate and showed this to my doctor. She put me on a 12 lead ecg and sent me to a cardiologist after that. In August of 2021 I received a pacemaker to control Sick Sinus Syndrome. Without the feedback from the watch I might have ignored the symptoms, passed out while driving and killed myself or someone else. There is a place for wearable technology especially when it prompts you to go to your doctor. My pacemaker will do a much better job of reporting any rhythm irregularities but I have to thank the Apple Watch for the initial detection of the issues I was having.

Smart watches aren't accurate but neither is medical equipment. That's why they tell you to average blood pressure readings and heart rates can show 140 one second and 40 the next.

You're right, averages and trends with any med-tech are always more useful than snapshot readings, since we're always adapting to our environment . If we kept a pulse of 60 bpm every second, we'd collapse every time we needed to run somewhere!

A trained profession can only look at it if he well looks. Software might not be 100% correct and as pointed out only has 1 datapoint but its better than not having ANY hints at all. Its like not having any engine lights and just waiting for the car to stop and yell 'clearly something is wrong now'. Also second remark is kind of silly a modern watch can now check 4 or 5 vitals making it very much like a engine check light giving the signal 'we think something is wrong' go check with a professional. Since its some of these vitals are not 24h you can also send the 'log' of the event (like in a car) for example the ECG that the watch made while not perfect and we hope a full 10lead ECG can confirm its better than nothing.

There is a new watch called Cardiac Sense and it’s Israel technology and supposed to be very very accurate. But it’s expensive. Do you have any idea about this as I have MVP and AFib and I am told by my cardiologist to wear one?

The last thing I need as a doctor is 21 year old Stacey sending me a million “abnormal” ecgs after heavy night out every Friday

[@ismathem]

Haha funny.

[@scb2scb2]

Thats your job.. It might save a few Stacey's. Filtering and trying to get the false detections down is important but its way better than not detecting at all just because its too much work. Get better tools and methods on your side.
