Ventricular Tachycardia – Mechanism

Transcript

Your ventricles are responsible for pumping blood to your body and the lungs. With healthy hearts, there is a consistent electrical stimulus provided by the natural pacemaker within the right atrium. This sinus node stimulates your heart’s electrical activity. When you are in ventricular tachycardia, this electrical activity is compromised because the ventricles are firing abnormally, which interferes with your heart’s natural pacemaker. The result is faster than normal heart rates, which prevents the heart from filling between contractions. This reduces blood flow to the rest of the body.
