question: I am 48, 1.6 meters and weight 51 kg. I just had my 24 hour holter. The report showed basic sinus rhythm with heart rate between 47 to 116 bpm. Total 302 premature ventricular beats and 3200 premature supraventricular beats seen. longest Rr interval 1.816 sec. What does it mean? Does it cause danger? Thank your for your answer.
