Overview

Historical Perspective

  • In 1894, Dr. Engelmann described a phenomenon of AV interval lengthening. Dr. Engelmann described a stimulus that is applied to the atrium followed by elongation of the AV interval.[1]
  • In 1925, Dr. Ashmar further studied this blocked impulses and their impact on the conduction in the muscle of the heart.
  • Dr. Ashmar stated the early blocked beats that follow a normal impulses have less effect on the conduction system.
