I had an abnormal ekg from trazadone. Of course was taken off that. Ekg returned to normal. After a month I think of taking seroquel was having some chest pains so I asked for another ekg but that one did come back normal. Dr said if I still continued having pains they would do a stress test but I didn't want one and the pains have disappeared too. I had no symptoms with the trazadone but the pdoc wanted to check an ekg anyway and I am glad it was done.
