Let me clarify A heart attack in the near future was a certainty. The irregular and sipping beats brought on the blackout. Had I recovered from the blackout and just sent right back into the cruel world without finding out what caused it, my heart was just a ticking bomb. Fortunately the doctors pressed on to find the cause. Consequently they found blocked arteries, really had no symptoms, blood pressure was normal and cholesterol was within limits. Looking back there were some other dots I should have connected but thought they were just from job stress and advancing years. the doctors and hospitals I was at were terrific.
