My heart doctor has documented that the ventricles of my heart are stiff. I have a problem with my heart misfiring, I think he said it was pvc tachycardia. He has me on a drug called verapimil, to lower my blood pressure, but I already have low blood pressure, have had all my life. I am wondering what other kinds of treatment options I have and if cardio work outs are okay for me. I do have asthma and a rapid heart rate normally, around 90 beats per minutes. It is coming down, but I still get a pounding heart, especially after eating. Could you give me more detail about this pvc proble
