- 1. Any record on paper or film made by an electrical event. 2. In electrophysiology, a recording taken directly from the surface by unipolar or bipolar leads.- His bundle e. (HBE) an e. recorded from the His bundle, either in the experimental animal or in humans during electrophysiologic cardiac catheterization.
* * *elec·tro·gram i-'lek-trə-.gram n a tracing of the electrical potentials of a tissue (as the brain or heart) made by means of electrodes placed directly in the tissue instead of on the surface of the body
* * *elec·tro·gram (e-lekґtro-gram) [electro- + -gram] any record produced by changes in electric potential, such as an electrocardiogram or electroencephalogram.
