In this video, Dr. K K Aggarwal, President Heart Care Foundation of India and Group Editor in Chief MEDtalks, will explain why miss beats are a cause of concern. These are premature contractions or extra beats. One of the beat might be of lower strength and the next beat will be of higher strength and it feels as if a miss beat. He further tells that if any miss beat comes with exertion then it might be a sign of underlying heart disease. Miss beats which comes on rest and disappears on exercise are to be ignored.
