Dear Dr, I am experiencing palpitations for a month now one or two plap. every now and then (sometimes 3-5 a minute and sometimes 1 every 3-5 hours), I have visited my doctor and he ran some test, like blood tests and told me to do a cat-scan for arteries and everything came back normal, still it didn't stop. I have eliminated my caffeine intake and reduced my smoking to the minimum and i don't drink. but that seems to be not effective. what should i do to stop it, it really bothers me every day.
