In 2020 at the beginning of Covid,I felt short of breath and walked up the hill to the clinic. After sitting waiting about 10 minutes for the nurse, she said my pulse rate was 144/minute. I was 79. Your formula says my max rate is 131. I didn't have Covid, or any chest pain or any feeling of heart racing. Right now my pulse is 67/minute.

[@clover7359]

Higher heart rates are like higher rpms in a car engine. Higher rpm, harder to get air into the engine to mix with fuel, so it makes less power, and there is a sweet spot in the speed range where peak power is reached, just like the heart. Higher bpm means less blood can enter the chambers of the heart, so less is pumped around, and there's a sweet spot of bpm where the heart is pumping the maximum amount of blood.

[@kuessebrama]

180-190 was my heart beat when i first started running, not the whole run but evertime when it was slowly getting extremly hard :D Yeah but i had it one time without sport and it was not funny, ok i know from where it came, because i was dumb in my youth and mixed a few substances wich should not be mixed and that got me into a panic attack or something like that and i thought the whole time that i get a heart attack any minute, or that i already got one because i had chestpain too, not cool and i've learned about my mistakes, but yeah like i said that was already extremly scary but to get a hear rate off 300 must be hard, i mean it is so fast you could not really count it if you would try to messure it with your finger or so.

[@Leslie_ann_h]

​@@benvanzon3234 I managed to hit 240 BUT I have severe dysautonomia and it was secondary SVT, unfortunately because it is caused by my brainstem jacking up my heart rate so defibrillation and typical meds to reverse SVT have no effect on me. Luckily, IV routed metroprolol, a dose of IV routed opiate and a dose propofol can help (depressing communication between the brainstem and heart as the three drugs are nervous system depressants and combining them just means a stay in an ICU).

[@fromulus]

I have psvt(Paroxysmal supraventricular tachycardia), that extra pathway for electricity. I didn't experience symptoms until my early 20's. The highest bpm I ever recorded during an episode was 237 bpm, but I don't doubt I've reached higher than that. At this point, I'm pretty good at getting it to go back to a normal rythym, usually within about 15 minutes. If I'm unable to get it to stop within an hour, it's time for the er. Last time I had to go they injected me with adenosine, it makes your heart completely stop for about a second, then it kicks in again at a normal rythym, ideally. What a terrifying feeling that was.

[@fromulus]

@@SakiMcGee I've been offered an ablation procedure, but I'm hesitant to do any surgery much less one involving my heart. My plan is if I ever get to the point that it's uncontrollable, then I'll get it done. So far so good. I probably get maybe 2 to 3 episodes a year, but it's manageable. Even my Dr said as long as I can get it to go back to normal fairly quickly it doesn't pose a health risk to me. It's the prolonged over-pumping for an hour or more that causes damage.

Pro Tip: When you get an electric shock, the frequency is key for being unable to let go and disrupting your heart rhythm, high frequencies burn instead of zap. It has something to do on how fast can muscle fibers polarize. Also what determine how hurt you would be is the total energy(Volts x Amps x Time), that's why you don't die by static shocks like when you touch a Van der Graaf generator

[@kuessebrama]

Yeah very high frequencies are going to act like DC and the normal house frequencie so 50/60 hertz, depends on where you life will be more dangerous for the heart.

[@DulcetCatharsis]

A fun little note I learned from my welding safety classes, it's specifically AC current that makes your muscles contract uncontrollably. It's because of the rapidly oscillating current that confuses your muscles. Direct current, while still dangerous, doesn't cause your muscles to contract (or at least not as bad, never say never and all that)

[@pierreuntel1970]

What? No it's the complete reverse, the DC will make your muscle clamp so hard that you will not be able to release it, the AC however, since it has to cross a 0V somewhere and go negative, it will make your muscle short of a "vibrating" feel and theoretically is easier to release

[@DulcetCatharsis]

@@pierreuntel1970 I wasn't trying to say that DC can't cause your muscles to contract at all, if that's what you thought. It's just that usually a DC shock yields one large muscle contraction, often times away from the source. AC shocks, on the other hand, cause multiple smaller contractions, that create muscles spasms that make it harder to control the muscles

Whoever told you that DC doesn't cause contractions is dead wrong and giving you very dangerous "advice".

I went and asked ChatGPT (4o model) for terms relating to this phenomenon, as I experience the same thing very often, and have always been curious about this.

Hematophobia (or Blood-Injury Phobia) 7. Visceral Reactions In my opinion none of these describe this exact feeling/phenomenon... And it also seems that this topic just hasen't been studied, like, at all... But one more term that's useful here is "health anxiety". Anxiety about your own health could be triggered by watching content about medical topics. If these feelings start to bother you, I would recommend trying to consciously relax your body while watching medical videos, and to repeat in your mind, that you are fine, and that it is normal to feel what you feel, and that it will go away slowly. I hope you can still feed your curiosities about medicine, because it's a very interesting and useful topic!

I was actually born with WPW Syndrome but it didn't become an issue until I was 2 month old in 1982. As a baby my heart rate could reach 300BPM and as I got older it could reach 200BPM. I had it corrected in 1997 when a new much simpler method became a thing that involved a 6-8 surgery of 4 catheters which were cameras and a 5th one that basically burned the extra path causing the problem. While that pretty much solved my problem, I still have an elevated heart rate of usually somewhere between 85-100BPM even resting and occasionally I experience sudden Tachycardia where my heart rate will go to over 100BPM. The worst thing about having WPW Syndrome is theres still a possibility it can return at a later age even after being corrected and ones who have the extra pathway on the left side are at a higher risk of complications during corrective surgery and a higher risk of it returning and lucky for me my problem was on the left side. Nowadays technology has advaced greatly and correcting it is not nearly as invasive as it was in the 1990's.

I have a weird not yet identified condition where my normal resting heart rate is 110-120 which is tachycardia. Sometimes it may be at around 90 which is considered normal. Now the weird part is that, sometimes it decides to drop drastically, reaching at it's lowest 42 BPM (Has reached 30 during sleep, though). It's most common during emotional stressors but may also occur for no reason. I usually begin to feel a sudden sense of calm and comfort and becoming insanely sleepy, and I often enter some weird stage between conscious and unconscious. A few times I've completely blacked out, other times I retain the ability to hear but become unable to move, sometimes I enter a hypnagogic stage where I retain awareness of my surroundings but have dreams that somehow occurs simultaneously, and sometimes I will in some weird way be able to remember and understand what people say after I've "woken up" despite not understanding my surroundings at the time. Even if there is a strong correlation between my heart rate and this weird sleepiness, my heart rate weirdly enough doesn't always seem to slow down during these things. A couple of times I have retained a heart rate of 110 BPM despite being so sleepy I had to rest my head on the table. I underwent a cardiac ultra sound recently as my doctors were alarmed by the symptoms, and weirdly enough no abnormalities of the heart muscle were detected. Interestingly though, the cardiologist noted that my heart seems to be abnormally reactive to signals from the nervous system, noting how I apparently went from lying down with a heart rate of 90 BPM to entering tachycardia at 130 BPM simply by him entering the room, and it's not like I was scared or startled or anything, I just felt a little bit nervous.

Was so happy to see a video that goes into A&P and not just some comedic video that may just lightly gloss over the heart chambers or muscles

[@HeartTribe]

One time I pushed myself to the absolute limit running, and ran at 190. Above my theoretical limit. It was intense. Haha.

[@Horticarter41]

The scene from Home Alone 2 you showed still makes me laugh hysterically at 42 as it did when I was 10. I don't know why, I just love the gags in the 2nd one more.

[@julesjackson4855]

Fun fact, when Neil Armstrong touched down on the Moon, his heart rate read approximately 156.

[@dominikjurkovic5540]

Last year i messured 220 bpm by running for an entry in crime analitics facult. I was 20 and it was 30 plus celsius outside. Nailed the entry tho. Havent even worked out for it.

[@kalanpagnucco1148]

I’ve been maxed out at 202bpm during an intense workout on my bike. I was insanely exhausted

[@martinschirmmann9551]

Same, I am 20 and my peak bpm recorded by my Apple Watch while boxing or my late (intense) stage of warm-up before boxing is about 202/203. During sleep it drops down to 55-48 bpm.

After having gone through three cancer episodes, the first one in 2012, I stopped doing my three mile "run" three times per week at age 63. I'm 74 now and thinking about trying to get back to doing thee miles a couple times per week. Going to start tomorrow gradually working my way up. I worried about my heart, but a stress test a few months ago showed I'm just fine. With a maximum heart rate of 136 (210-74), I'm certainly not going to break any records.

[@Glowingenergy]

At 2:10 is that a real heart?

Thank-you heart, you've done a lot for us

[@tomasstell-ortiz9974]

I have a three heart conditions, SVT, AFIB, and Tachycardia. One time my heart rate got to just over 200. I’m now know as “the kid with the heart problem” on westpoint because the whole staff was called in incase I had a heart attack!

[@Nick550]

I have SVT and my highest recorded heart rate was 194bpm. This was when I was 29

[@mousermind]

My highest recorded BPM since I started wearing a smart watch was 189, well over my theoretical limit.

[@Freya_games_and_music]

When I was 16 I overdosed on caffeine pills because my friend and I made a bet that I couldn't stay awake for 7 days straight. Well on the third day I was popping caffeine pills every 30 to 45 minutes. Halfway through the school day I kept feeling tightness in my chest and was having trouble breathing. I could feel my heart was racing and I was feeling like total shit. I finally went to the school nurse and told her I was sick and needed to go home. She took my temperature and it was normal, but she saw that I was sweating like crazy so she checked my pulse and almost immediately pulled her hand back and yelled for someone to call an ambulance. I got the the hospital and they put me on the heart rate monitor and my heart was beating between 230-280, it wouldn't stay at a set rate, just jumped up and down but never went below 230. I told them the truth that I had been taking caffeine pills to stay awake. They ended up giving me activated charcoal and some IV meds to lower my heart rate. And I was released the next day only to be told that I was grounded for a month for my stupidity.

[@constantineshaman3336]

I'm 22 but my boy beats around 220 during cardio training, running or cycling for example. Sometimes higher, absolute max after intense sprinting for 10 minutes was 232. It felt ok, absolutely to problem. I was just hearing air in my ears like i'm yawning every breath for couple minutes, and was ready for another intense sprint just in 1 minute.

[@Byeiquit-v9p]

My fastest was 211 bpm and I was doing about 15 mph to 20 mph

[@javanmyna]

Woah, didn't even think that fast heart beat is even possible. Interesting vid

[@redbeebreadsYT]

quick question what does "Must be this tall to ride"? 0:20

[@PhillipH-san]

I'm assuming this is a question of English. It's a joke. At amusement parks there are signs that say guests must be "this tall to ride" a given ride. For safety reasons, people below a certain height can not ride some rides (like roller coasters) if they are too short because the saftey devices on the ride are not designed for someone of that height. I honestly don't know what the joke is. I guess because they said that the heart has its "shortcomings".

[@martinramos1737]

I’m 22 and love running. When I was in shape at 16 running around 40-50 miles a week for two years straight my heart rate couldn’t go above 180 now at 22 out of shape I measure my hr on my Apple Watch and a treadmill bpm counter to hit 210 but I can’t hold it for more than a minute I talked to my doctor and have had multiple heart studies and everything is healthy. They say that the max numbers are theoretical and vary amongst people. If I can get it to 210 during exercise then that’s fine just be careful staying up there for too long.

[@scarlettsteele7999]

My max heart rate is apparently 185 which is scary because I’ve had a heart rate of 190 bpm in the hospital. I forget what exactly was wrong with me but I manage it with medication now.

I have adhd and took Adderall in highschool. I had pretty intense pe classes and my heart would get get to 204/205 bmp. That’s my highest recorded heart rate.

I am a amateur cyclist and tested my maxHR multiple times. I am 19 and currently it is 206 bpm. So, the rule of thumb doesn't allways apply.

@Anitamil Anitami bruh

[@kittycatcaoimhe]

It's possible that there was artifacting due to the actual tremors I was dealing with, but I have POTS (a type of tachycardia), was experiencing chronic tachycardia, then on top of that was having very frequent seizures that put me in the ER, and the HR monitor was reading over 180 for a while, shot up above 210 (I forget if it was 216 or 226, because I was bordering on unconscious), then read "++" before falling back down into the 170-190 range (this part I have only somewhat lucid memory of, but it was corroborated by the people who went with me to the ER). I passed out right about then, so I wouldn't doubt that a brief spike into the 220+ range could have caused that. That being said, even 170+ makes me feel like absolute shit, so even if the heart can *mechanically* beat over 200 bpm in a young adult, I wouldn't say it can *functionally* beat that high, especially not for very long. I've slowly worked my resting HR down from ~110 a few years ago to ~88 now, so even in my tachycardia episodes, I'm typically "only" in the high 160s/low 170s nowadays.

I had WPW syndrome and my maximum heartrate was 237bpm. Had an ablation and I'm fine now

[@Ryno_YT]

Yooo, same here. Never actually seen/spoke to anyone that also had WPW. Happy to see all went well. Sometimes I panic about it ever returning whenever I get palpitations, but I have to keep in mind that it's most probably anxiety/stress/panic-attack induced, especially since I went through the operation while I was still young.

[@ShrihariV6105]

@@Ryno_YT Eyy nice to meet you!! Dw man I had the procedure when I was 11, and I'm going to turn 18 this year and I'm doing well, so I assure you won't have any problems!!!! I also have Ebstein anomaly, and with that I play football(or soccer if you're american lol) regularly. Don't think about it too much just enjoy your life like any other person would. Wish you a Happy and healthy life mate!!!

[@Kronnikk]

Suffered AVNRT, a form of SVT. Heart rate would go from resting 70bpm to 200bpm in a single beat. Drs brushed it off as panic attacks for a decade before one realized & rushed me in for an ablation

[@Jayderzomb]

I love the example with your wife haha

[@alexthebudgie9071]

Back when I had cancer when I was 12, about a year into treatment o was in hospital with an infection and I was hooked up to a machine during a routine check. At one point the monitor started screaming at my nurse and she decided to take my pulse manually. I saw this nurse who’d I’d seen many times over the past year and a bit have her colour drain from her face, my heart rate was In the low 300s. She sat there for a second and decided to take my heart rate again on the machine. It started dropping down to the 240s. She called in the doctors (but later told me if it didn’t drop so much in that couple minutes she’d have had to press the emergency alarm that alarms the entire ward and other doctors I’m the hospital). The next couple of days it stayed at 190 ish beats, whilst I spent the whole night in bed. She told me she didn’t believe it which is why she did it twice and took it manually on my pulse or something. I had to have ECGs, wires connected to my whole body for ages. Literally like the next day too I started having spasms in my muscle tissue all over my body and was in agony. I also ended up having mucousitis so that was fun. I’m glad I didn’t need the emergency button pushed because I already have diagnosed PTSD from everything, although now when I have PTSD reliving and flashbacks and memories, and my anxiety starts up- I can always feel my heart rate and I worry it’s happening again.

[@TheToxicity862]

Can you source where you got 210 minus age? I've always been taught 220 minus age in all my cardiology training

[@chrisspinks7718]

I believe you are right.

[@Salim_Habib]

It's different in each country..

[@thurbine2411]

[@seagie382]

210 minus age, but I was able to comfortably hit 220 doing cardio at age 16

[@ratintosh]

probably depends on more factors like weight, height, etc.

[@assetaden6662]

That's a general thing. You can go above 220 or your max could be 150.

[@WeAreASecret]

OMG I think you just helped solve a mystery of what happened to me one time. When you were going through the case of Jack Searle, I could have sworn you were talking about me a bit over a year ago. The heart racing faster than i could count, exhaustion, grey skin... That 300bpm heart rate example sounded wayyy too familiar. I don't have an accessory pathway in my heart, but I do have another issue that affects the same part of my heart and can make it go crazy out of nowhere. Sounds like it went EXTRA crazy one day, got damaged some, and that's why I've been having to recover all this past year
