If you have ventricular tachycardia, your doctor may give you medicine to slow your heart rate down. You might also need a catheter ablation. In this procedure, a doctor threads a thin tube through an ...

Despite advances in defibrillation technology, shock-refractory ventricular fibrillation remains common during out-of-hospital cardiac arrest. Double sequential external defibrillation (DSED; rapid ...

Monomorphic ventricular tachycardia is an irregular heartbeat where the bottom chambers of your heart beat quicker than usual. It can cause symptoms such as shortness of breath, dizziness, or fatigue.

Ventricular tachycardia (V-tach or VT) is when the lower chamber of the heart beats too fast to pump efficiently. This ...
