3.3 Vertical distance from the tip of the pacing electrode to
the coronary artery
Tables 2.1 and 2.2 show the vertical distances from the end-systolic
LBBAP pacing electrode to the branches of the coronary artery. The
average distance from the tip of the pacing electrode to the anterior
descending branch was shorter than that to the posterior descending
branch (19.69 ± 8.72 mm) vs (26. 09 8 ± 02mm). The mean distance from
the electrode tip to the left ventricular posterior branch of the right
coronary artery (21.11 ± 7.86 mm) was similar to the average distance to
the anterior descending branch. This suggests a higher risk of damage to
the anterior descending branches and a lower risk of damage to the
posterior descending branches. In addition, the minimum distances from
the tip of the electrode to the anterior descending branch, posterior
descending branch and left ventricular posterior branches were 5.28 mm,
9.51 mm and 8.69 mm, respectively, and the maximum distances were 43.07
mm, 44.11 mm and 42.50 mm, respectively. The ranges of the distance were
37.79 mm, 34.60 mm and 33.81 mm, respectively.
