| Popis: | BackgroundAlthough powerful defibrillation devices are available in clinical practice, risk stratification is important in asymptomatic Brugada syndrome. In this study, vector-projected 187-channel electrocardiogram (VP-ECG) was used to calculate the ST-elevation score in Brugada-type ECG and test its usefulness in risk stratification.Methods and resultsVP-ECG was recorded in 108 patients with Brugada-type ECG having ventricular fibrillation (VF) episodes (±; n=13/95). The ST morphologies were evaluated in 80/187 precordial leads. The coved- and saddleback types (4–6 vs. 1–3 points) of ST-elevation scores in 332 recordings were 58±57 points, which were calculated using virtual ECG leads. Compared with types 1–3 ECG patterns, the scores were significantly different among the groups (107±65, 62±45, and 14±22, respectively; p |
