Letter to the editor
Substrate mapping during sinus rhythm aids VT characterization; leaves open prospective validation of high-density algorithms.
We read with great interest the article by Vlachos et al.1 Because of the high incidence of nonhemodynamically tolerated ventricular arrhythmias, the recent paradigm shift has led to the development of mapping strategies during sinus rhythm. This article provided an excellent review of various high-density signal processing algorithms and mapping techniques for substrate characterization.
