I'm a 28-year-old woman and I've noticed something odd with my heart rate. Even though I don't have any family history of heart disease and I'm generally healthy, my heart suddenly races from normal up to 127 to 170 bpm. This happens when I'm just resting or even asleep and can last for 5 to 15 minutes each time. It occurs about 2 to 5 times a day and I've been experiencing this since I was 7 years old. I'm starting to get a bit worried about it. What could be causing this?
u require echo test and a cardiologist opinion
