We'll finally got some answers to what the GP was happy to pass off as ectopic beats...results from echiocardiagram were clear but 24hr monitor showed paroxysmal AF. saw cardiologist yesterday and she has prescribed 1.25mg of beta blockers...first time ever taking anything for the palpitations and I'm scared. I'm only 38 but want to star5 to feel normal again. she said the results had shown 2 instances of heart rate at 200+ BPM!!
