What Hacienda says. Really worth watching your HR recover after an effort - e.g. clibing a hill to a junction, lights on red - how quick does the heart rate come down ?
Mine is about 50 ish - It was 55 when having blood pressure taken ready for steroid injections, so that ain't bad under 'stress'.
It was 32 on the operating table when I had my shoulder done - took a good note of the readings afterwards - 32 for ages and ages, then went to 44, and eventually back to normal as I came round.
