His bundle electrogram
Also found in: Dictionary, Acronyms, Encyclopedia.
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.
His bun·dle e·lec·tro·gram (HBE),(hiz),
an electrogram recorded from the His bundle, either in the experimental animal or in humans during electrophysiologic cardiac catheterization.
His bundle electrogram (HBE)
Etymology: Wilhelm His, Jr., German physician, 1863-1934
a direct recording of the electrical activity in the atrioventricular bundle (bundle of His).
His bun·dle e·lec·tro·gram(HBE) (hiz bŭn'dĕl ĕ-lek'trō-gram)
