Change in echocardiographic and electrocardiographic parameters post-cardiac resynchronization therapy (CRT). (A) Mean change in left ventricular ejection fraction (LVEF) at 6 (3.7 ± 9.1%) and 24 months from baseline (4.3 ± 12.0%). (B) Mean change in left ventricular end-diastolic dimension (LVEDD) at 6 (−1.5 ± 4.8 mm) and 24 months from baseline (−1.6 ± 4.2 mm). (C) Mean change in QRS duration at 6 months (−13.6 ± 30.2 ms). Six-month data depicted in blue, 24-month data in orange. Whiskers represent minimum and maximum values, horizontal line is median, box represents interquartile range and x is the mean change from baseline (average of patient-level change).
