Resetting and entrainment are pacing techniques that were essential in determining the reentrant nature of ventricular tachycardia (VT) complicating healed infarction and most other forms of structural heart disease. In addition, entrainment mapping is a powerful strategy for mapping well-tolerated monomorphic VT. However, given the incredible power of three-dimensional mapping systems and the rise of substrate based VT ablation, questions arise about the relevance of these classical electrophysiologic techniques. This chapter will discuss the continued importance of these techniques, highlighting in particular their use in clarifying VT mechanism and in verifying the data obtained from activation mapping.
