Heart Rates

[ardx74]

Dear Doctor,

Stats: 29/M/190LBS General Good health (PVC's/PAC's once every few days or so) My question is again related to heart rates.  In a visit to a Cardio about 4 years ago, my resting heart rate was 58BPM.  The last four months I've been on a work-out regime of 40 minutes of weigh training and 20 minutes of running (5K in 22 minutes) 4-5 per week while maintaing a well balanced diet and sheding about 15LBS.  I've noticed that my resting heart rate is now between 42-46BPM. 1. I've never felth dizzy, short of breath or have felt any symptoms as a result - should I be concerned? 2. Furthermore I can only a achieve a maximum rate of 176BPM as monitored by my watch, about 20 short in theory - is normal considering my lower resting HR?

Thank you for your response and this wonderful forum.

i recently experienced what my local docs thought was a heart a ttack. i went in the e.r. with chest pain and tightness in the chest and pain radiating down my arm. was on a nitro drip and transported to a cardiology critical care unit at a university hosp. they monitored my heart rate and did a heart cath. while with them at the university i had another attack and since my family history says death from heart problems they are concerned. at the hosp. a couple of times my heart rate dropped into the middle twenties and my blood preasure has been flux  from high to low. any reason why?
