Another option is to get rid of the spot in the muscle with a procedure called catheter ablation. In this procedure, a thin flexible catheter is floated up from a large vein in the leg all the way up to the inside of your heart. Once inside the heart, the catheter is placed right on top of the problem spot in the muscle, and using the catheter, the tissue is gently heated up to 60-degrees C. This will denature the tissue and a permanent scar will form, curing the problem in over 90 percent of cases.
Ventricular tachycardia comes in many forms. There are types of ventricular tachycardia that can be life-threatening. It does not sound like you have a dangerous type of ventricular tachycardia but it is important that you have your doctor follow this closely. If you haven't seen your doctor recently, I would make an appointment and have your doctor discuss the possibility of either medications or catheter ablation to better control your episodes.
