Question: I have a resting heart rate that goes into the 50 ' s mostly at night. If I go to watch TV in the evening and sit on the couch my heart rate slows down to the low to mid 50 ' s . I have lost a lot of weight over the past 10 months from 295 LBS down to 220 Lbs. However I do not exercise very much. Is this normal. I'm worried because it feels so slow. Sometimes when I get up from the couch I'll feel 5 or 6 slow hard heart beats until it speeds up during movement. Usually with any movement my heart rate speeds up accordingly.

Hi Doctor. I have had a whole cardiac work up including holter monitors, echo, ECG, and stress test. All were normal. The holter showed sinus rythm with rare PACS. it showed my average heart rate was 71 and went as low as 41 bpm during sleep. My cardiologist says my heart is structurally normal and that I have a healthy heart. I have had all blood work done as well and results were normal. The weight loss was due to a big change in diet. I switched to eating plenty of raw fruits and vegetables, quinoa and chicken and fish. I made a dramatic dietary change over the last 10 months. I just get worried because my resting heart rate gets into the low 50 ' s when I lay on the couch. Doctor says it's my heart relaxing from working harder during the day. Does this sound right. I've seen 2 cardiologists
