Wedge, that is exactly my attitude. Most pacemakers are there to improve the quality of life. I could live without mine, but there would be issues, i.e. slow heart beat when I am asleep. I feel really good all most all of the time and am very thankful for the doctors, nurses, and engineers, etc. who make this medical technlogy possible. I told this to my caridac doctor and he said you will live longer if you live to the fullest. Please contact you pacer company (like you stated). Yours has defib and is more critical than mine.
