May support bi-septal pacing in refractory LBBB-HF; hypothesis-generating, requires randomized confirmation before practice change.
Leonard M. Rademakers (2019) conducted a case report in Heart failure with complete left bundle branch block (n=1). Left bundle branch area pacing was evaluated on QRS width. Left bundle branch area pacing successfully shortened the QRS width from 180 ms to 95 ms and improved the patient's NYHA class from III to II.
