Figure 2 Standard electrocardiogram (ECG) leads V1 to V3 of a typical intermittent course taken from a subject with a Brugada-type ECG. From 1965, we observed the Brugada-type ECG with "coved"-type ST segment elevation in lead V1 and "saddle-shaped"-type ST segment elevation in leads V2 and V3. Transient normalization was observed in 1977, but the ECG reverted to the Brugada type in 1979. Maximal ST segment elevation in leads V1 to V3 developed in 1981.
