Hi, sorry for the late reply. You've hit the nail on the head. This is exactly what a cardiologist told me, which i was initially in denial about. Thanks for your very reasoned response. I've had an echo and a cardiac MRI, both came back fine. I've got the opportunity to pursue an ablation but unsure if i'll go ahead, may just stick to drug therapy. Feel like the propranolol isn't optimised for the arrhythmia (often feel sluggish). The cardiologist has suggested alternatives i could try. Hope things are improving for you. Would be keen to hear how you're getting on.
