There can be three possible reasons for your low heart rate
. One, you have always had a low heart rate and it is normal for you. Secondly, you are on some medications like beta blockers (propranolol
, atenolol etc) which reduce heart rate. Thirdly, you may be suffering from hypothyroidism
in which weight gain and low heart rate are common. You should also get an ECG done to rule out any arrythmia. Please consult a cardiologist
so that your concerns can be assessed and a proper evaluation done.
