The mean seizure threshold was stable and unchanged postoperatively at the 1, 3, 6, 12 and 24\u2010month follow\u2010up. The paced QRS duration of the LBBP was 119.72\u2009\u00b1\u20092.53\u2009ms and &lt;130\u2009ms in all patients. Unipolar impedance during the procedure was higher than 500\u2009\u03a9 (662.00\u2009\u00b1\u2009181.50\u2009\u03a9). No ventricular septal perforation occurred at the end of the procedure. At the 1\u2010month follow\u2010up, two patients reported transthoracic echocardiography, with CT revealing septal lead perforation. Through CT, two other patients were found to have septal lead perforation, and echocardiography indicated that the pacing lead had penetrated the interventricular septum and entered the left subendocardium. At the 1, 3, 6, 12 and 24\u2010month follow\u2010up, these four patients exhibited no significant increase in pacing threshold or impedance (<jats:italic>p<\/jats:italic>\u2009&gt;\u2009.05).
