My husband is a 52 year old man in excellent health. Works out, eats well, doesn t smoke or drink. For the last two weeks he said he has felt his heart pounding when he exerts himself. He said it is minimal exertion and yet he can feel his heart pounding. It eventually stops. And doesn t happen all the time. But it is concerning. He will make an appointment to see his physician. Until then, any advice as to what this could be? Should he be going to emerge and not waiting to see the doctor? THanks.
