I have high pulse during the day 95-105 but normal in the morning. and mild chest pain in ribs and sternum. in the last two days I stayed the night in hospital, Had numerous blood tests, Stress Tests, EKGs,.. My heart seems to be fine and undamaged. I take Candesartan and metropolol. What should I do now to find out the cause of the Heart rate issue and this annoying chest pain. Cardiologist says, don t worry lose 20lbs and exercise. Im 42yr, male, non-smoker, 5 -9 204lbs.
