Supraventricular Tachycardia (SVT, PSVT) Symptoms

PSVT can cause a number of symptoms, depending on a person's overall health and how fast their heart is beating. People with heart damage or other coexisting medical problems experience a greater degree of discomfort and complications than those who are healthy. Some people have no symptoms at all.

Symptoms can come on suddenly and may go away by themselves; they can last a few minutes or as long as 1-2 days. The rapid beating of the heart during PSVT can make the heart a less effective pump so that the body organs do not receive enough blood to work normally. The following symptoms are typical with a rapid pulse of 140-250 beats per minute:

In infants and very young children, symptoms are sometimes difficult to discern. However, those infants with irritability, poor feeding, sweating, poor coloration of skin, and who exhibit a pulse rate of 200-250 beats per minute may have PSVT.
