Permanent Bi-Bundle Pacing in a Patient With Heart Failure and Left Bundle Branch Block

Left bundle branch pacing (LBBP) is effective in patients with heart failure, left ventricular ejection fraction (LVEF) of ≤35%, and a widened QRS complex. LBBP leads to iatrogenic incomplete right bundle branch block (iRBBB). Bi-bundle pacing can resolve iRBBB, further narrowing the QRS duration, a...

Sumario:Left bundle branch pacing (LBBP) is effective in patients with heart failure, left ventricular ejection fraction (LVEF) of ≤35%, and a widened QRS complex. LBBP leads to iatrogenic incomplete right bundle branch block (iRBBB). Bi-bundle pacing can resolve iRBBB, further narrowing the QRS duration, and may improve LVEF. (Level of Difficulty: Advanced.)
