When at rest, the heart of a healthy adult beats steadily at a rhythmic rate of approximately 60 to 100 beats every minute. Heart rate is lower in very fit individuals and elite athletes. The heart rate can be checked or measured by taking a pulse manually or using a specially designed device. Ventricular tachycardia is a cardiac disorder or arrhythmia triggered by abnormal electrical signals in the ventricles found in the lower chambers of the heart.
Tachycardia is a cardiac disorder where the heart is unexpectedly beating too fast or faster than what is usual for that person in that particular situation. Exercise, fear, or stress naturally elevate heart rate. Doctors usually diagnose problematic tachycardia when the heart rate is measured and found to be higher than 100 beats per minute when these factors are not present.
