Question

Explain in simpler terms " Ventricular tachycardia. VT arises from a single, rapidly firing ventricular ectopic focus, typically located at the border of an old infarction. The focus drives the ventricles at a rate of 150 to 250 beats per minute. Because the ventricles cannot pump effectively at these rates, immediate intervention is required. Cardioversion is the treatment of choice. If cardioversion fails to normalize rhythm, intravenous amiodarone should be administered; lidocaine and procainamide are alternatives. For long-term management, drugs (e.g., sotalol, amiodarone) or an ICD may be employed."
