I am a 59 year old woman who weighs 273 pounds and who has lost over 3 stone in the last five months from healthy eating and a challenging exercise programme. My resting heart rate was 60-65 when I started but as I became fitter it gradually fell further so that now shortly after rising in the morning it well below 50 beats a minute. Is this OK or should I be worried? My blood pressure has also gone down quite a lot through exercise - from on average 105/72 to on average 99/66.
HI Susieq: A resting rate of below 50 is a little unusual, but not dangerous. Are you on medications that could be lowering the heart rate? Beta blockers, Alpha blockers, even some calcium channel blockers?
If you have no symptoms of lightheadedness, weakness, fatigue, fainting- then it's probably OK.
Best to check with your doctor.
I hope this helps,
Dr. Kirk Laman
