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.
