My husband is 41 yrs old, a smoker, with no significant PMH. He started having heart palpitations a few days ago. He had episodes like this a few years ago and was told it was stress . Now he is saying they bother him most when he lays down and he can t sleep. He has no SOB, CP, dizziness , fatigue or other symptoms. Can we wait and follow up with our PCP or is this something that needs more immediate attention?
