The paced QRS duration and the stimulus to left ventricular activation time were 106.8 \u00b1\u20096.8 ms and 65.5 \u00b1\u20095.4 ms, respectively. Left bundle branch (LBB) potential was recorded in 61.1% (11\/18) patients who succeeded in LBBP. During the procedure, the mean unipolar myocardium capture threshold was 0.51\u2009\u00b1\u20090.15\u2009V@0.4 ms while the unipolar bundle capture threshold was 0.84\u2009\u00b1\u20090.51\u2009V@0.4 ms. The mean fluoroscopic exposure time and the radiation dose were 13.0 \u00b1\u20099.2\u2009min and 81.7 \u00b1\u20098.3 mGy, respectively. The average follow\u2010up period was 10.4 \u00b1\u20095.9 months (range 3\u201023\u2009months).
