Shanghai Score (Brugada Diagnosis) Calculator

  • Spontaneous Type 1 ECG (Yes = 1, No = 0)
  • Fever-Induced Type 1 ECG (Yes = 1, No = 0)
  • Provocative Drug Test Positive (Yes = 1, No = 0)
  • Documented Ventricular Fibrillation / Polymorphic VT (Yes = 1, No = 0)
  • Family History of SCD < 45 years (Yes = 1, No = 0)
  • Probable Pathogenic SCN5A Mutation (Yes = 1, No = 0)
  • Shanghai Score for Brugada Syndrome: Explanation and Clinical Context
    The Shanghai Score is a diagnostic scoring system developed to assess the likelihood of Brugada Syndrome based on clinical, electrocardiographic, familial, and genetic criteria.
    It assigns weighted points to spontaneous Type 1 ECG, fever-induced or drug-provoked Type 1 ECG, documented ventricular arrhythmias, family history of sudden cardiac death, and presence of pathogenic SCN5A mutations.
    Scores >3.5 indicate a likely diagnosis, scores 2–3.5 suggest possible Brugada Syndrome requiring further evaluation, and scores <2 make the diagnosis unlikely.
    This tool helps clinicians in standardized diagnosis, risk stratification, and management planning for patients suspected of Brugada Syndrome.
