I have various heart issues, including AF, PACs, PVCs and sinus tachycardia during panic attacks. However, recently I've experienced the occasional strong, thumping beat (which is lso a tiny bit painful). I've only ever experienced these thumps one at a time - they never manifest as couplets, triplets etc, like the ectopics I'm used to.
Does anyone else experience these slightly painful, hard and very disconcerting thumps?
