Doctors call this type of heartbeat supraventricular tachycardia, or SVT. SVT happens when electrical signals in your heart’s atria get out of sync.

How is the heart rate regulated in ventricular tachycardia?
Ventricular tachycardia heartbeat. Your heart rate is regulated by electrical signals sent across heart tissues. A healthy heart normally beats about 60 to 100 times a minute when at rest and is defined by signals that originate in the upper chambers of the heart (atria). In ventricular tachycardia (V-tach or VT),…
