Pseudo‐2:1 bundle branch block. “Fusion causes confusion”

The fusion of narrow‐QRS sinus‐generated beats with end‐diastolic ventricular extrasystoles occurring in bigeminy can produce an electrocardiographic pattern difficult to differentiate from parasystole. Such an ECG should not be interpreted as 2:1 RBBB because of the variability of the PR intervals....
