Wavefront‐Like <scp>LAM</scp> Method: A Case Report of Residual Potential Identification Using Local Voltage Derived From Late Annotation Mapping

The Wavefront-like LAM method preserves wavefront-based timing consistency while enabling quantitative local voltage evaluation. This method improves differentiation between low-voltage and no-voltage regions and suggests that residual potentials appearing isolated on conventional voltage mapping can be identified.
