Waking up with heart palpations serveral times a night. i have had anxiety issues in past. had a normal holter monitor and ekg 6 months ago. is it safe to say this is just anxiety and not a heart issue? no other symptoms except occasional ear ringing?

While anxiety is definitely contributing once awake, medical clearance would be recommended. Specifically sleep related disorders will have to be considered as potentially causing such symptoms, usually sleep studies may help clarify. Start with an evaluation with your primary care doc who should be able to further coordinate locally.

It is not feasible to provide an opinion without additional history, physical examination may be some tests. It would be prudent to see your doctor to see if you may be depressed. Depression is treatable. Counter-intuitive as it may seem, exercise may help. Start with low intensity exercise such as walking and gradually increase the intensity as tolerated. Drink more water. Wish you good health!
