The median age at implant was 17 years (IQR 13, 40). Among the patients with successful BBAP, the median QRSd was 128\u2009ms (IQR 120, 132), and the median V6\u2010RWPT was 72\u2009ms (IQR 58, 80). In the subgroup of patients who underwent successful BBAP for improved synchrony, there was a significant reduction in the QRSd (167\u2009ms [IQR 147\u2009186] vs. 132\u2009ms [IQR 127\u2009135];\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.01). Electrical parameters remained stable over 4\u20136 months of follow\u2010up apart from threshold, which had a statistically significant but clinically irrelevant rise; this was followed by stabilization (threshold at last follow\u2010up was 0.75\u2009V at 0.4\u2009ms [IQR 0.7\u2009V, 1\u2009V]). Before\u2010 and after\u2010pacing ejection fraction (EF) was unchanged in systemic left ventricle (LV) group (LVEF 58% [IQR 48%, 62%] vs. 60% [IQR 54%, 64%];\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.44).
