Thanks every one
I am back home recovering now , the surgery went well but no driving for a month ,& nothing heavy for 2-3 months. I ask the doctor about detecting and explained what was involved in the hobby. Unless winter holds off i am probably finished for the season. On the bright side the heart feels stronger , and we are considering a vacation in the Philippines next year. Better to loose a little time this year,and feel top of my game next year. Please don't ignore those chest pains if i had waited longer i might not have been around to detect.
