question: I have mitral valve prolapse which drstically increased my heart rate and has been controlled for several years by a bet blocker. recently i have developed herniated discs in my neck and have been in a lot of pain, have been laying around a lot and not watching my diet. Since this started I noticed my heartrate has increased again even though I am taking the beta blocker. other than getting more exercise once I can and watching my diet again is there anything else you would suggest to get my heart rate back down?
