WS mapping highlighted regions of high CV and conduction heterogeneity, which partially overlapped with PF and ILAM\u2010defined substrate areas. In some cases, WS mapping revealed broader or discordant zones, suggesting it may capture conduction dynamics not identified by conventional markers. Ablation in WS\u2010identified regions resulted in VT termination or noninducibility. Functional validation techniques (e.g., entrainment) were limited by VT noninducibility or hemodynamic instability.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>WS mapping may offer complementary insights into conduction heterogeneity and mismatch within VT substrates.
