electrogram

[e-lek´tro-gram] 1. any record produced by changes in electric potential.2. specifically, a cardiogram taken from the chambers of the heart or from a specific position within the chambers.His bundle electrogram an intracardiac electrogram of potentials in the lower right atrium, atrioventricular node, and His-Purkinje system, obtained by positioning intracardiac electrodes near the tricuspid valve; it is used to pinpoint the site, extent, and mechanisms of arrhythmias and conduction defects.intracardiac electrogram a record of changes in the electric potentials of specific cardiac loci as measured by electrodes placed within the heart via cardiac catheters; it is used for loci that cannot be assessed by body surface electrodes, such as the bundle of His or other regions within the cardiac conducting system.
