3.2 Distribution position of the pacing electrodes in the nine
partition method
As shown in Figure 3, at RAO 30°, the red dots represent the
two-dimensional distribution of the tips of the LBBAP electrodes in 50
patients. Among these, 28 pacing electrodes were in the PM position, 14
in the M position, 5 in the PI position, and 3 in the MI position. All
pacing electrodes were located in the PM, M, PI and MI positions or in
the junction area. Overall, 84% of the electrodes were located in the
PM and M positions, and the pacing electrodes were densely distributed
in the PM position.
