“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.
In adults and children over 15, resting heart rate faster than 100 beats per minute is labeled tachycardia. Tachycardia may result in palpitation; however, tachycardia is not necessarily an arrhythmia. Increased heart rate is a normal response to physical exercise or emotional stress.
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 ...

A normal resting heart rate is 60 to 100 beats per minute. A resting heart rate of more than 100 beats per minute is defined as a tachycardia. During an episode of SVT, the heart beats about 150 to 220 times per minute. [9] Specific treatment depends on the type of SVT [5] and can include medications, medical procedures, or surgery. [5]
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.
