Figure 1. Flow diagram of selection process for articles
included in the meta-analysis.
Figure 2. Forest plot for the meta-analysis comparing impact of
LBBAP on QRS duration and LVEF. A. Changes in QRS duration before and
after LBBAP. B. Changes in LVEF before and after LBBAP.
Plot demonstrating significant reduction in QRS duration and significant
improvement in LVEF.
Square data markers represent mean diference of QRS duration (A) and
LVEF (B) between pre implantation and post implantation, and horizontal
lines represent 95% CIs.
LBBAP, left bundle branch area pacing; LVEF, left ventricular ejection
fraction; SD, standard deviation; CI, confdent interval.
