There is the characteristic ST-segment elevation >= 2 mm in >=1 right precordial leads (V1 to V3), following an r'-wave and a straight ST-segment. Additionally, the descending ST-segment crosses the isoelectric line and is followed by a negative and symmetric T wave. At 40 ms of high takeoff, the decrease in amplitude of ST is <=4 mm and the duration of QRS is longer than that in a right bundle branch block. No high-pass filters were applied to attenuate low-frequency noise. (a) Admission ECG leads V1 and V2 upon presentation, showing coved ST-segment elevation (black arrows) with elevated J points, suggestive of a Brugada type 1 pattern. (b) Subsequent ECG showing resolution of the Brugada type 1 pattern (black arrows).

ST-segment elevation in V1 and V2 suggestive of a Brugada type 1 pattern (Figure 1(a)). She was treated with aspirin, ticagrelor, intravenous heparin and nitroglycerin infusions, high-intensity statin, beta-adrenergic and calcium channel blockade, angiotensin-converting enzyme inhibition, and mineralocorticoid receptor antagonist pharmacotherapy. Subsequent ECGs done when pain-free revealed normalization of the Brugada pattern (Figure 1(b)).
