What is the fastest that a human heart can beat before it explodes?

Question

I know that it won't actually explode. I just meant that it will give out, explode just sounded better.

Answer 1

It doesn't explode per se. I guess I've seen it at 220 beat per minute. That is almost 4 beats per second. It is called superventricular tachycardia. Broken down: the bottom part of the heart moving swiftly. The heart will just stop beating or beat irregularly fast until it does stop.

The heart never seems to not amaze me, when you think about it the heart is a 'beast' literally. Its a pump that never stops, and it is so strong you can feel the force of the heart pumping when you feel the pulses. This may seem silly, but to me it is amazing how our bodies work. With that being said your heart needs to be able to pump blood and be able to 'pump a certain amount' of blood each time it beats. When your heart is not pumping enough blood each time it beats, your heart will compensate and 'speed up' so it can make up for the inadequate supply of blood not being pumped. Even though the heart can speed up to make up for this, it can only withstand this for so long. Your heart won't actually 'explode' from pumping to fast it will just 'tire out'. The fastest heart rate i have ever seen on a adult was between 198-212, and this person was in critical condition. Needless to say I don't wait around to see how long the heart will last before 'it tires out'.

Answer 4

I am an ultra marathoner, ironman and endurance mountain biker with an ICD (defibrillator). I was out riding on a training ride and had a ventricular tachycardia occur and the defibrillator went off 8 second from the onset. I was still riding during and shortly after. My heart rate was beating at 315 for those eight seconds and I was still peddling. I definitely felt it and slowed down before the defib happened. During my initial onset and hospitalization I was beating at 220 to 240 for 2 hours and 15 minutes before the ER meds converted the rhythm. During that initial onset I rode about 7 miles back to my house where I put on a heart rate monitor and the first rate I saw was 240.

So to answer your question technically, the heart can beat 315bpm for at least 8 seconds. I was flown out to a cardiology conference to speak about the experience and none of the cardiologist, except my EP doctor, could believe anyone could be conscience at that rate.

Answer 5

It won't explode at any possible rate. But at a certain point it beats so hard that it becomes totally inefficient. The fastest heart rate I have ever heard of has been 300. Mine got up to 240 once when I had a reaction to something the dentist injected me with and I didn't die.

Answer 6

I think an answer would vary depending on the health of the particular heart. I remember years ago when I used to be a very avid bicycle rider/racer, my wife got concerned one night as she slept with her head upon my chest, that my heart beat only 3 beats on the 4 beat cycle, and, her being in the medical profession, asked my doctor the next day when she was at work whether I was "at risk" of some heart problem because of that. My doctor's response to her was, "Your husband's heart is so healthy that it takes only 3 beats to do what everyone else's heart takes 4 beats to do." Yes, I was proud of that since I knew my doctor was attentive to my very good health as a result of my bicycle riding/racing, and as I watch the Tour de France bicycle race in France each summer, I'm awed at what I know to be their exceptionally healthy hearts. I know that there must be a rate at which the human heart must seize while in the human body due to over exertion, but, I think that has to do with the particular person's health. And I guess there is a laboratory test result somewhere that gives a statistical norm which would be excellent for your question. I'm just not privy to that information, and since I divorced that wife (or, she divorced me), I guess that shuts out my being privy to medical sources right now that would answer your question. Sorry. God Bless you.

Answer 7

Highest Heart Rate Ever

Answer 8

There is no definitive answer for this, the heart is a wonderful and amazing thing. If you are unwell, then the heart can beat up to 200 per minute, but again it all depends on the person etc etc.

Answer 9

I've recorded my own heart rate at up to 300 BPM during heavy exercise. There was a time in my life when my resting heart rate sat around 120 BPM. I need to start working out more.

Answer 10

its not going to explode but mine was sustained at between 300 and 400 bpm for over an hour. As soon as the Dr.s find out about something like that you are immediately cardioverted and your heart never works the same. (at least in my experience.) So I would assume that it doesn t go much higher than that.
