In brief: Abnl heart rhythm
Afib is short for atrial fibrillation which is an abnormal heart rhythm where your heart speeds & slows down on its own without any good reason.
It can be confirmed by an ekg/ecg or electrocardiogram where your doctor will tell you that you're missing p waves (the signal from the atria). Afib increases your risk of stroke and may warrant taking blood thinners.
