What Heart Rate From Tachycardia is Deadly?

[Unregistered4351]

The other day i was spazzing out and literally counting my pulse to a stopwatch and googling. I guess over 100 BPM is the definition. Can i live at 140 to 150? What is the exact BPM and time that can kill you???

There isn't one. It depends heavily on your physical condition, age, etc. but even then, there's no magical mechanism that makes you suddenly drop dead if your heart rate is elevated for a time.

I'd say anything over 200 was extremely dangerous. But 300 lethal.

I once spiked at 190 in the hospital for a "panic attack." Most of the time, I was at 165bpm, which was scary, but not life-threatening, said the doctor.
