Conclusions
The site of PES has a marked effect on inducibility of VT in some patients such that PES from the RV apex and outflow regions will fail to expose clinically relevant VTs. The frequency with which this occurs is not certain. Stimulation from alternative sites is a reasonable consideration in selected patients.
