Figure 1 Sample Holter monitor tracings recorded from one patient during the onset and termination of atrial fibrillation (AF). In each figure the top tracing is a bipolar recording from the right atrial epicardial wires, and the bottom tracing is a recording from surface lead I. In A, the second atrial premature beat (arrow) initiates a rapid atrial rhythm of varying morphology which can easily be identified by the atrial electrograms. On the surface electrocardiogram this rhythm appeared to be AF. B demonstrates the spontaneous conversion of AF to sinus rhythm in the same patient.
