late potentialCardiology A high-frequency, low-amplitude signal at the tail of a QRS complex, which is attributed to fragmented and delayed electrical conduction through the borders of a myocardial scar; delayed conduction of LPs allows reentry of electrical impulses and ↑ susceptibility to ventricular arrhythmias
Deflections found on signal-averaged electrocardiograms that follow the QRS complex and point to an increased likelihood of ventricular dysrhythmias. These deflections represent delays in electrical conduction through the ventricles.
