I have had a stress test(walking machine pointed uphill) and passed with flying colours. I do not want to be paranoid and start going to specialists when I don't need to. I note all your comments and think that a heart monitor would be an improvement over a timex watch with a pulse readout.
I just find it alarming when hiking in the mountains with a 30lb backpack and I come to a hill and have to stop every 20yards after I get a pulse warning. The warning continues until I reach level ground. Maybe at the age of 66 this is normal and means I should walk slower, have a lighter backpack(ie. do dayhikes !!!!) I don't know what
is normal for my age. I walk about an hour a day at 3mph no problem. Blood pressure is normal when I am seated when I get back. Just the high pulse is alarming when I really exert myself. All your comments are appreciated
