This sophisticated module provides significant training and practice opportunities in three electrode leads placement (LV, RV and RA). The simulation, designed to help develop competence in electrophysiology interventions, includes real life sensing and pacing measurements, and enables clinicians to cope with procedural arrhythmia complications. The CRM module provides a variety of realistic anatomies including variations in the CS ostium (e.g. Thebesian valve) and coronary sinus vasculature.
