Tachycardia can be triggered by:
It is of great concern when the condition is caused by cardiac
arrhythmias, which is a short-circuit in the electrical impulses controlling your heartbeat, resulting in the heart to beat too rapidly.
Other forms of tachycardia are:
Supraventricular tachycardia (SVT)
This is a prevalent
arrhythmia in young adults. This is experienced as a sudden burst of rapid heartbeats that begin and end abruptly, lasting for seconds or hours. SVT is usually not life-threatening.
Ventricular tachycardia (VT)
Ventricular tachycardia is a very rapid, but regular heartbeat of 100 beats or more a minute occurring in the lower chambers (ventricles) of the heart.
Sustained heart palpitations lasting more than 30 seconds are considered a medical emergency. They could indicate pre-existing heart diseases such as coronary artery disease or heart valve disorders.
