Overview
First-degree AV block was first described by Dr. Engelmann in 1984. Dr. Ashmar further studied the blocked impulses and their impact on the conduction in the myocardium.
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 these blocked impulses and their impact on the conduction in the muscle of the heart.
- Dr. Ashmar stated the early blocked beats that follow normal impulses have less effect on the conduction system.
