A patient with sinus node dysfunction and left bundle branch block received His bundle pacing. This advanced pacemaker therapy normalized QRS duration, improving cardiac function.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Devices

Background:

  • A 78-year-old male presented with syncope due to intermittent sinus bradycardia and left bundle branch block (LBBB).
  • His baseline ECG showed a QRS width of 160 ms, and echocardiogram revealed a left ventricular ejection fraction of 45%.

Observation:

  • The patient underwent pacemaker insertion due to symptomatic sinus node dysfunction and a diseased left bundle.
  • Electrode placement was confirmed via fluoroscopy.

Findings:

  • Post-pacemaker implantation, the patient's QRS width normalized to 80 ms.
  • Device check confirmed excellent function.

Implications:

  • His bundle pacing effectively corrected the conduction abnormalities.
