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?
Mitral prolapse is generally a benign condition but one that can lead to an uncomfortable awareness of the heart beat. Beta blockers reduce the hearts response to a Chat Doctor.  However, your heart rate is influenced by several other factors, most notably deconditioning (lying around doing nothing) and medications such as muscle relaxers and pain medicines. You have already identified the next step, increasing physical activity, preferably one that will not aggravate your neck condition. More medicine is not the answer.
