Good combination - bovine valve and pacer. I've had both of mine for almost 2 years now and they play well together. After things heal some more, be sure you have a good chat with your electrophysiologist about your life style, in order to ensure that they set your pacemaker properly for you. Post back or PM me when you want to discuss what that means. If you already know what I mean, you're ahead of most new pacer patients.
