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.
Discovery
- There is limited information about the historical perspective of third degree AV block.
OR
- Third degree AV block was first discovered by [name of scientist], a [nationality + occupation], in [year]/during/following [event].
- The association between [important risk factor/cause] and third degree AV block was made in/during [year/event].
- In [year], [scientist] was the first to discover the association between [risk factor] and the development of third degree AV block.
- In [year], [gene] mutations were first implicated in the pathogenesis of third degree AV block.
Landmark Events in the Development of Treatment Strategies
The First Implantable Pacemakers. In 1958, Åke Senning, a thoracic surgeon at the Karolinska Hospital in Stockholm, implanted myocardial electrodes and a pulse generator with a rechargeable nickel-cadmium battery in a 40-year-old patient.[2]
