When I go into AF I feel im about to burst my abdomen swells 4 inches. Is it because I increase my drug Bisopronol from 2 to 5mg, this has plagued me for years!! and no doctor can answer it. 17 cardioversions, I now try to get rate down with drug, takes 2-3 wks but sometimes works. Had 2 EE ONAblations but still go ino AF. IS this problem from AF or increase in drugs, I can hardly walk for wks, and still have to walk....help!!
