Figure 5 (A) Focal firing is shown in a voltage-activation map during a rapid triggered rhythm during acetylcholine + norepinephrine. The focal firing originates within the pulmonary vein (PV) sleeve. Asterisks mark the advancing concentric circular wavefront. The origin marked by the circle is shown in (B), voltage recording from the earliest site of activation after a pacing-pause stimulation sequence. Arrow = 0 ms.
