I am 55 years, from past 30 days i get sudden palpitations. my heart beats increase and suddely it lowers. That is it beats faster for 5 times and lowers suddenly 3 times. This goes on repeatedly. Mostly I get these palpitations while I lie down. Three years ago I was diagonised that I have Mitrial Vavle prolapse. I have not consulted any doctor for the palpitation. Do I need to consult any doc for this? What could be the possible reasons?
