Successfully achieved His-bundle pacing without a His-bundle potential
recorded: A case report
Abstract
A 75-year-old man with atrial fibrillation and III atrioventricular
block (AVB) with a slow escape rhythm and right bundle branch block
(RBBB) underwent His-bundle pacing (HBP). The procedure was guided by
the tricuspid valve annulus (TVA) visualisation technical without
His-bundle (HB) potentials recorded and got a low HB capture threshold.
The transition from non-selective (NS) -HBP to selective (S) -HBP can be
seen during the threshold test. It is possible to achieve HBP without HB
potentials recorded in the whole procedure.
