Supraventricular Tachycardia - Ongoing Concerns

If supraventricular tachycardia occurs in someone who has significant coronary artery disease, 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 (angina) or a heart attack.

Mild supraventricular tachycardia, with short episodes that don't happen often, doesn't typically weaken the heart or lead to heart failure. 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.

The Facts About Cardioversion

If you have an irregular heartbeat (called an arrhythmia), your doctor might suggest a treatment called cardioversion to help get your heart back into a normal rhythm. If your heart beats too fast or unevenly, it can be dangerous. Your heart may not be pumping enough blood to meet your body's needs. An irregular heartbeat also can lead to a stroke or a heart attack.
