My resting heart rate(i.e when lying Or sitting) is always between 50-60, sometimes even 48-50 bpm..But whenever I stand up or does work it returns to normal. Did ecg, echo and
thyroid profile. Ecg shows low heart rate, but echo test and thyroid profile was fine. My doctor told me not to worry about it. Is it normal or what should I do? I have no other problems except acid reflux
