“Untreated, if there is too much tachycardia for too long, it can put excess strain on the heart muscle by overworking it and it can cause abnormal heart enlargement and weakening of the heart ...
The fastest human ventricular conduction rate recorded to this day is a conducted tachyarrhythmia with ventricular rate of 600 beats per minute, [32] which is comparable to the heart rate of a mouse. For general purposes, a number of formulas are used to estimate HR max .
Think of your resting heart rate like the check engine light on your car dashboard; it can alert you to an underlying health issue of which you may otherwise be unaware.
Arrhythmias, also known as cardiac arrhythmias, are irregularities in the heartbeat, including when it is too fast or too slow. [2] A resting heart rate that is too fast – above 100 beats per minute in adults – is called tachycardia, and a resting heart rate that is too slow – below 60 beats per minute – is called bradycardia. [2]
It may be difficult to determine the rhythm's regularity when the rate exceeds 150 beats per minute. Depending on the patient's health and other variables such as medications taken for rate control, atrial fibrillation may cause heart rates that span from 50 to 250 beats per minute (or even higher if an accessory pathway is present). However ...

The adult heart beats at a resting rate close to 72 beats per minute. [10] Exercise temporarily increases the rate, but lowers it in the long term, and is good for heart health. [11] Cardiovascular diseases are the most common cause of death globally as of 2008, accounting for 30% of all human deaths.
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
