I've had a few scary episodes, normally around 2 am, when I wake up and my heart rate is around 98 bpm. I've had an ecg and an echo test and this picked up a very small hole in my heart. My consultant said it wasn't anything that needs attention but I'm wondering if this is causing the rapid beat. I also get ectopic beats, again apparently harmless (although very disconcerting). Any tips for managing this? Getting increasingly anxious !
