Fig. 2 — Parental ECG changes in case 1 on flecainide challenge tests. A: baseline ECG record of the father in case 1. No definite abnormality, but suspicious ST elevation is observed. B: ECG of the father in case 1 obtained after flecainide challenge. Equivocal coved ST-segment elevation followed by T wave inversion (type 1 Brugada pattern) is observed (arrow). C: baseline ECG record of the mother in case 1. Normal sinus rhythm without ST-segment elevation is observed. D: ECG of the mother in case 1 obtained after flecainide challenge. Considerable QRS widening with coved ST-segment elevation followed by T wave inversion (type 1 Brugada pattern) is observed in V1 and V2 leads (arrows). ECG: electrocardiogram.
