I have suffered from palpitations for years which was treated only sometimes successfully with Atenolol. Last year I also noticed that my heartbeat began to beat very strongly and surge from my chest through my ears and head. This is very disturbing. Everything disappeared after I had cardiac catheter ablation in May but after three weeks the strong, heavy heartbeat has returned (not the palpitations). They are worse than ever and I have to take Ambien to get to sleep. I am trying acupuncture, hypnotherapy, yoga but am getting no relief. I get chest pain and pain in arms but doc says all tests are ok. I have tried calcium, magnesium, hawthorn extract, CoQ10 also. I have been on paxil, lexapro, effexor, they do nothing for me. I am about to try homeopathy. Does anyone have a similar condition or have any advice for me? I am not able to get through my day and have dreadful difficulty trying to sleep - I use soothing music etc but as soon as I wake in the morning the pounding is there and lasts all day. I get no relief. I would appreciate any help/advice you can give.
