Just been diagnosed with afib. I'm 69 years old and in relatively good health. I'm an avid biker and swimmer. The afib has been causing me lots of problems with swimming. I've had issues on the bike as of late. This seems to be getting worse. I'm currently seeing an electrocardiologist and am wearing a halter monitor.My next visit back to the doctor is the end of November. This condition has turned my life around. They have me on blood thinners. Don't know where this is all heading. I've gone from being really active to waiting for the next shoe to drop. I guess I'm just wanting to know will I be able to lead an active lifestyle after this?
