July 9th, 2007, had a triple bypass, (80% blockage of left main); currently, resting hrt is 65 and BP is 120/70ish; 40 year type 1 diabetic with exceptioanl control; on 25mg of metoporlol (12/5 twice a day) and aspirin; hike 3-5 miles a day on a hill rail with ski ooles, etc....my problem is a racing heart rate that happens only at night, where the hrt gets to 110-120 BPM; I went to the emergency with it and my BP was 128/72!! no one can tell me what's going on...huge waiting list to see my cardio (the beauty of publicly fnded health care in Canada!!) I also have some minor aching type pain around the left mammary, which i attribute to the harvesting of the artery in that location...my ekg was normal each time I had the racing heart incident...can anyone shed some light on this? thanks
