I notice that almost everyone indicates that they are aware when an AF episode occurs, and that there has been a lot of advice to call an ambulance when the episode is particularly rough. While only occasionally I've felt what I assume to be AF -- a sort of mild fluttering -- I'm very aware of frequent palpitations and Premature Ventricular Contractions (are there what are called Ectopics in England?) but never certain that they are all a part of AF. Would welcome any comments about that, please!
But back to the ambulance question: Not long after the AF diagnosis, I had a severe and prolonged (two or threel hours) episode of palpitations and PVCs, with heart thumping and racing up to about 170. I eventually took an extra Flecainide and things gradually settled down. When I told the cardiologist about this, adding that I had come close to calling an ambulance, he made this remark: "Why would you call an ambulance? All they would do is an EKG and tell you that you have Atrial Fibrillation. Well, you already know you have AFib. All you need to do is take an extra Flecainide, not call for an ambulance."
