Preston, I aint no doctor or pharmacist, so I may not spell these things the way JAMA or the PDR does. My father had a tacacardia for years. He took Verapamil for years as well to stop to tacacardia. The Verapamil has some undesirable side effects that he got tired of dealing with, so he went to Emory Crawford Long earllier this year and had the tacacardia fixed. I understand the problem to be an electrical one, so his cardiologist fixed it by running a tube through the femoral artery all the way to his heart, zapped the shorted area of his heart, and Dad hasn't had the problem since.........and he flushed the Verapamil. I know that is sort of a layman's explanation, but you get the picture. So, other than his Parkinson's Disease, Dad is doing very well. I wish you the very best success during your treatment.
