Premature ventricular complex

A ventricular escape beat is an extra beat that originates within the ventricles. The QRS is always wide, because depolarisation does not spread via the normal conduction highways. Unlike a premature beat, an escape beat arrives later than expected.A premature ventricular complex (PVC) is an ectopic beat that originates in the ventricles with a wide QRS complex and no P wave. It may also be called a ventricular ectopic beat (VEB).eg transient PR prolongation after retrograde impulse from PVC, or RP interval with 2 alternative AV nodal pathways…

This ECG is from an elderly woman who presented with chest pain.

This ECG shows ST elevation V2-4 with poor R progression and hyperacute T waves. The cause was an acute LAD occlusion.
