Been having palpitations for past 30 years visited my go about a year ago and had an e c g and was referred to a cardiologist at local hospital because of fast heart rate but was told e c g itself was fine. Cardiologist then gave me another e c g and did something called a heart scan in darkened room. The only explanation he gave after having this done was I needed to lose wait and that the palpitations were not life threatening but sometimes they scare me so much I am female age 52 overweight and have just started menopause
