Fusion beats and Nonconducted PACs
On this page there are a variety of complexes present. The first complex shows a prolonged PR interval. The 2nd and 3rd complexes are PVCs with P waves or fusion complexes. On the 3rd complex there is a dropped P wave. It can be seen in lead aVR and aVL. This is followed by a short pause. The 4th complex shows a prolonged PR interval and it is followed by another nonconducted P wave. A short pause follows the nonconducted P wave, then sinus bradycardia with sinus arrhythmia follows.
