Figure 2. (A, B) Continuous recording: The 24-h Holter recording revealed apparently normal atrioventricular 1: 1 conduction before the transient episode of third-degree atrioventricular block, which was triggered by a nonconducted premature atrial contraction and the subsequent P-P pause of 1260 ms, leading to a ventricular asystole of 13.2 s (paper speed 25 mm/s).
