Electrical activity in Koch's triangle.
The authors have conducted several experimental studies of the cellular electrophysiology of the atrioventricular (AV) node employing the Langendorff-blood perfused heart of both dogs and pigs. Two types of experiments are described: experiments showing that cells with electrophysiological characteristics of typical nodal cells can be found outside Koch's triangle; and mapping experiments during the induction of ventricular echo beats in an attempt to delineate the reentrant circuit thought to underlie AV nodal reentry.
