Patients with MVP often have an increased sensitivity to pain and palpitations that may be mediated by an abnormality in the neural connection between the brain and the heart. The atenolol was started to limit your symptoms, but you were unable to tolerate it due to its side effects. Since alcohol, tobacco, and caffeine can all precipitate palpitations, I suggest that you avoid those substances. I don't know why you have intermittent episodes of palpitations, followed by prolonged periods without palpitations, but you should speak with your own physician regarding this question. I hope you find this information useful.
