I have been having heart palpitation since the last 2-3 months , they generally happen when I am lying down. I generally feel it like a lump in throat. I had a ecg done and it came out normal and my lipid , kft and lft reports were also normal. I was given nebicard 2.5mg for my palpitations and asked to take it for 2 months. Should I get any other test done to rule out if this is not related to CAD. Please advice.
