A sign that you might have a heart condition called Atrial fibrillation (AFib) - if your ticker races rather than beats and the feeling lasts for a few minutes. It’s a common heart condition and it doesn’t so much have types as it has durations. Healthcare providers classify it by how long it lasts, or what causes it- treatment depends on this. Faulty electrical signals make your heart flutter or beat too fast when you have this condition. This abnormal rhythm stops the ticker from pumping as efficiently as it should which can slow down flow of blood, slow enough to pool and form clots. Atrial fibrillation raises your chances for a stroke and other heart complications. Some of these symptoms, such as shortness of breath or chest pain, can imitate those of a heart attack.
