Why does my heart always beat faster and skip when im lying on my right side? when i turn over on my left side is calms down?

Your question suggests that this happens each time you lie on your right side. Sometimes the effort involved in rolling over may transiently increase your heart rate. Observe your heart when you roll over to your left. Also observe whether any activity tends to do the same. If you are otherwise healthy, this is unlikely to be of concern. I would urge you to see your doctor for further guidance..
