Hi, my boyfriend is experiencing a very low pulse rate (44) although he normally has a low pulse, about 50. He has been feeling faint and light headed for two days with a stomach ache, and has been sleeping and drinking fluids to combat this. Do you have any suggestions?
Hello, It's a matter of concern. First we need to find out a cause. Possible reason includes, thyroid problem, potassium abnormalities or sometimes problems in heart pacemaker called sinus node.  He should get one ECG and holder monitoring done. Also, thyroid and kidney function test are needed. If we are able to find some treatable cause then it's fine, otherwise he may need pacemaker depending upon a cause.
