electrogram

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.
