Histopathological findings in three children with His bundle tachycardia occurring subsequent to cardiac surgery

Eur Heart J. 1992 May;13(5):709-12. doi: 10.1093/oxfordjournals.eurheartj.a060239.

Abstract

This report concerns three children with His bundle tachycardia who died following cardiac surgery. At autopsy the conduction system was examined in detail. In all three, the sinus node was intact and supplied by a well-formed artery. Haemorrhagic tracks were identified invading the penetrating atrioventricular bundle. The tracks originated from stitches placed close to the conduction tissue. The hypothesis that disruption of the conduction tissue results in an arrhythmogenic focus is discussed.
