Congenital Long QT Syndrome (LQTS) — Key References for the QSP Model

Curated bibliography supporting the mechanistic map, mrgsolve ODE model, and Shiny dashboard. References were selected from well-established, widely-cited LQTS/CiPA literature. Where the exact PMID could not be confirmed with full confidence, a PubMed search URL is given instead of a guessed numeric ID. Grouped by topic; an asterisk (★) marks primary parameter/calibration anchors for the model.
