Atrial flutter symptoms can come and go, with fast heart beat episodes lasting from some hours or days. In some cases, atrial flutter happens all the time. With proper treatment, atrial flutter is rarely life threatening. Complications of atrial flutter can be serious, but they can usually be prevented with treatment.
With atrial fibrillation , your heartbeat loses its rhythm and causes a quiver or fluttering in your chest. It can last for a few seconds or a few days, and it can raise your risk of stroke, blood clots, and other heart problems. A pulse of electricity tells the four chambers in your heart when to squeeze to send the blood through.
