Firstly what a great Forum. Very reassuring. Thanks to all contributors. 2 years ago I went to the supermarket and woke up in an ambulance very scary. From this diagnosed with af and an irregular heartbeat although no reason for the collapse found. Since then I've had 3 visits to A and E with rapid and irregular heartbeat and each time I convinced myself that this was the end and I'm not being melodramatic. I am now on bisoprol 7.5 and apixiban as well as blood pressure and cholesterol medication. This is the best I felt for over 2 years but the thought that something serious could happen any time really scares me. I'm just wondering if anyone out there has collapsed and been told it was a result of af? Also any advice on alcohol consumption and exercise. I am a 60 years old male. Thanks in anticipation and good health to all.
