Supraventricular Tachycardia

If supraventricular tachycardia occurs in someone who has significant Reference coronary artery disease Opens New Window, the heart may not receive enough blood to keep up with the demands of the increased heart rate. If this occurs, the heart may not get enough oxygen, potentially causing chest pain (Reference angina Opens New Window) or a Reference heart attack Opens New Window.

Mild supraventricular tachycardia, with short episodes that don't happen often, doesn't typically weaken the heart or lead to Reference heart failure Opens New Window. But some people have a higher risk of getting heart failure, such as those who have a heart valve disease. If tachycardia is left untreated, repeated and long episodes of tachycardia can lead to heart failure (known as a tachycardia-mediated cardiomyopathy). But this heart failure might be stopped, or reversed, if the supraventricular tachycardia is stopped with treatment.
