Left bundle branch pacing was achieved by penetrating the interventricular septum (IVS) into the left side sub-endocardium with the pacing lead. His-bundle pacing (HBP) was successfully performed in another 29 patients, 19 of whom had right ventricular septal pacing (RVSP) for backup pacing. The QRS duration, left ventricular (LV) activation time (LVAT), and mechanical synchrony using phase analysis of gated SPECT myocardial perfusion imaging were evaluated. Paced QRS duration in LBBP group was significantly shorter than that in RVSP group (117.8\u2009\u00b1\u200911.0\u2009ms vs. 158.1\u2009\u00b1\u200911.1\u2009ms, P\u2009&lt;\u20090.0001) and wider than that in HBP group (99.7\u2009\u00b1\u200915.6\u2009ms, P\u2009&lt;\u20090.0001). Left bundle branch potential was recorded during procedure in 37 patients (67.3%). Left bundle branch pacing patients with potential had shorter LVAT than those without potential (73.1\u2009\u00b1\u200911.3\u2009ms vs. 83.2\u2009\u00b1\u200916.8\u2009ms, P\u2009=\u20090.03). Left bundle branch pacing patients with potential had similar LV mechanical synchrony to those in HBP group. R-wave amplitude and capture threshold of LBBP were 17.0\u2009\u00b1\u20096.7\u2009mV and 0.5\u2009\u00b1\u20090.1\u2009V, respectively at implant and remained stable during a mean follow-up of 4.5\u2009months without lead-related complications.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Permanent LBBP through IVS is safe and feasible in bradycardia patients.
