My heart rate races when i lay down almost every night, it wakes me up. is this dangerous?

Heart rate: See your doctor to be checked out, lots of possible reasons from abnormal structure and function to anxiety.

Usually benign: Get checked though for thyroid disorder, arrythmia (svt, pvc) etc. Or could just be anxiety/panic attack. Have u had holter monitoring done? Cut down on caffeine, soda, energy drinks and alcohol. Go see your dr for a repeat ekg. May need a beta blocker. If stress echo is normal, it means your heart is structurally sound. You are still young to have serious heart ailment.Give us some feedback!
