Rate?: Count the rate. Pay attention to whether it's regular or irregular. (at your wrist, neck, chest, or arm). If it's 100 while you are resting, see if your doctor can order a 24 hour (holter) heart recording to determine what rhythm your heart is in. Most likely, you've simply become aware of your heart - felt best when lying left side down.
