    ECG: Atrial Fibrillation

    An ECG strip shows the presence of atrial fibrillation, which involves rapid, uncoordinated electrical activity in the atria. Atrial fibrillation is indicated by an erratic rhythm. The ventricular (QRS) rate here is normal (but can be very rapid). A normal ECG strip is shown at the bottom for comparison.
