Figure 2.

The impact of new PPI when depth of implant relative to MS length is considered. The rate of new PPI was numerically higher overall and in all MS length groups when NCC implant depth was greater than or equal to MS length. Grey = Overall new PPI rate in subgroup. Blue = New PPI rate in subgroup when NCC implant depth is less than MS length. Red = New PPI rate in subgroup when NCC implant depth is greater than or equal to MS length.

Abbreviations: MS, membranous septum; NCC, noncoronary cusp; PPI, permanent pacemaker implantation.
