Hi, I m a 43 year old female, with 110/68 blood pressure, 164 total cholesterol , all normal bloodwork, 75 glucose , work out with weights and play tennis at least 5 times a week. I m about 15 lbs overweight .. I get constant palpatations, especially when I start my workout and my heart rate increases. I can just be relaxing and get them. I had an EKG in the past, all normal. My resting heart rate is like 78. It happens just about everyday, I heard about an electrolyte imbalance or hormones..just curious to also know if I can tell if it s valve related. Thanks
