Patient
23-year-old man hospitalized for syncope with history of familial sudden death;
Trace
Tracing evocative of Brugada syndrome with coved ST elevation in V1, V2, V3 with negative T-wave and absence of reciprocity;
Patient
57-year-old man with multiple factors hospitalized for typical chest pain;
Trace
Elevation in the inferior leads (Pardee wave), convex upwards, > 5 mm, encompassing the T-wave; the elevation generally reaches its maximal amplitude within a few hours; reciprocal depression in V2 and in leads I, aVL; minimal q waves in the inferior leads; coronary angiography revealed right coronary thrombosis;
Exergue
In the presence of chest pain and a ST segment elevation, certain signs are suggestive of an ischemic origin: convex upward elevation, broad, corresponding to a defined coronary territory, with negative T-wave and necrosis q wave, evolving over a period of a few hours.
Except for the early repolarization pattern, the normality criterion for ST segment elevation is that the ST segment must not deviate more than 1 mm above the isoelectric line.
