About four years ago, I was diagnosed with ventricular tachicardia. I was given a catheter ablation to treat it, and it corrected an irregular heart beat that I've had since I can remember, but I still experience the rapid heart beats every now and again when Im out running or doing some other strenuous activity. Another thing that I've had since I can remember is excessive sweating, and I mean very excessive. What it takes for a normal person to sweat, it would take A LOT LESS for me. My question is, is the excessive sweating linked to the tachycardia? Of course, tachycardia causes the fast heart beat which in turn causes the sweating, but even when Im not experiencing the rapid irregular heart beats, I still manage to completely soak a t shirt when the guy next to me whose done the same amount of work is completely dry, aside from a few sweat beads on the forehead.
