You won't see me: can pacing correlation maps be used to assess scar location?

In ventricular tachycardia (VT) ablation, substrate-based approaches have emerged as an alternative approach to activation-based VT ablation, which is often limited when clinical arrhythmias are non-inducible, non-sustained, and/or hemodynamically compromising. Traditionally, substrate mapping is performed in sinus or paced rhythm, and comprises of annotation of abnormal electrograms, including low voltage, fractionated, and late potentials This article is protected by copyright.
