Abstract

High Resolution Electrocardiography is a very specialized type of surface ECG which involves computerized analysis of small segments of a standard ECG in order to detect abnormalities, termed Ventricular Late Potentials (VLP) that would be otherwise obscured by skeletal muscle and electrical noise. There are various types of these low amplitude signals which can be detected by High Resolution Electrocardiography but the most important are Ventricular Late Potentials and the main clinical use of High Resolution Electrocardiography is to detect these VLPs. Ventricular Late Potentials are present in terminal part of QRS complex and these may extend into ST segment as well; hence the name “late potentials†because they arise late in ventricular activation process.
