Supraventricular Tachychardia

Friday, March 18, 2011

The term tachycardia refers to a rapid heartbeat of more than 100 beats per minute. Supraventricular tachycardia is a rapid rhythm of the heart that begins in the upper chambers. Dr. Edward Hill gets us up to speed on SVT in todays 60 Second Housecall.

Dr. Hill:

The term supraventricular tachycardia, or SVT, describes several types of fast heart rates that usually arent dangerous, but can cause troubling symptoms.

These symptoms include a fast heart rate, tiredness, shortness of breath, dizziness or feeling like youre going to faint. The fast heart rate usually starts and ends suddenly and can last for minutes to hours.

Treatment is needed when you have serious symptoms, such as dizziness, chest pain or fainting. Treatment also is needed when SVT could weaken your heart or increase your chances of dying.

Your doctor may treat you with medication or a catheter ablation procedure. If the medicine doesnt work or isnt needed, a catheter ablation procedure can be done in a hospital. Your doctor will thread a wire to your heart through a vein in your leg. This wire delivers cold or hot energy to your heart to destroy the abnormal tissue that is causing the fast heart rate. This is usually a small amount of tissue.
