  Figure 1. Premature Ventricular Complex Initiating Atrial Fibrillation Premature ventricular complexes initiating atrial fibrillation are denoted by the red arrow. Preceding sinus beats with P-waves are denoted by blue arrows.

  Figure 2. Frequent Left Bundle, Inferior Axis Premature Ventricular Complexes (A) Frequent left bundle, inferior axis premature ventricular complexes noted during the patient’s ablation procedure. (B) Representative premature ventricular complex with retrograde conduction with a VA interval of 161 ms. Baseline PR interval of 176 ms.

  Figure 3. Strips of Overnight Telemetry Monitoring Showing Salvos of Self-Limited Atrial Fibrillation (A) Strips of overnight telemetry monitoring showed salvos of self-limited atrial fibrillation initiated by premature ventricular complexes denoted by the red arrows. (B) Post-procedural ambulatory rhythm monitor showed episodes of atrial fibrillation initiated by a premature ventricular complex denoted by the red arrow.
