Left bundle branch pacing
"LBBP is defined if fulfilling criterion 1 and at least one in criteria 2:~1. Paced morphology of RBBD in surface lead V1 (QR, Qr, rSr', rSR' or Qrs);~2. One of the following should be met:~ 1. Selective LBBP with an iso-electrical window between the pacing spike and QRS onset;~ 2. If using dual-lead method with one at His-bundle and the other at LBB region, a retrograde His-bundle potential is recorded from His-bundle lead during LBBP;~ 3. LVATs at lead tip pacing of 1.5V/0.5ms and 10V/0.5ms are ≤ 80ms and the difference is \< 10ms;~ 4. A discrete LBB potential is recorded from lead tip and LVAT at tip pacing of 3V/0.5ms is ≤ 80ms19.~If criterion 1 is fulfilled but none in criteria 2 is met, the procedure is considered to be left ventricular septal pacing (LVSP)."
Right ventricular pacing
Implantation of a RV pacing lead is attempted using the standard-of-care technique first.
