Abstract
Cardiac pacing is the only effective therapy for patients with
symptomatic brady-arrhythmia. Traditional right ventricular apical
pacing causes electrical and mechanical dyssynchrony resulting in left
ventricular dysfunction, recurrent heart failure and atrial arrhythmias.
Physiological pacing activates the normal cardiac conduction thereby
providing synchronized contraction of ventricles. Though His bundle
pacing (HBP) acts as an ideal physiological pacing modality, it is
technically challenging and associated with troubleshooting issues
during follow up. Left bundle branch pacing (LBBP) has been suggested as
an effective alternative to overcome the limitations of HBP as it
provides low and stable pacing threshold, lead stability and correction
of distal conduction system disease. This paper will focus on the
implantation technique, troubleshooting, clinical implications and a
review of published literature of LBBP
