I am 8+1 and in 2009 had an ablation for tachycardia. Since then, I have experienced ectopic heartbeats that my GP says are harmless. Nonetheless, before I got pregnant I cut out caffeine and cut way back on alcohol, which has helped. Stress seems to make it worse, though. Does anyone else suffer from irregular heartbeats? Will it likely affect my fitness to give birth? I will ask my MW but first appt isn't till 17 July.
