Abstract
Late potentials are low-amplitude, high-frequency signals which are continuous with the QRS complex and last a variable time into the ST segment. These signals are believed to originate in myocardial zones with slow and inhomogeneous activation patterns. In all probability, they are due to the delayed depolarization of relatively normal ventricular tissue within a diseased area [1,2]. Myocardial areas involved in the generation of late potentials may serve as the underlying anatomic substrate for malignant re-entrant ventricular arrhythmias. Hence, late potentials may be considered as hallmarks of life-threatening sustained ventricular tachycardias, and the accurate detection of these signals may be of vital interest to prevent the sudden death of some patients.
