Suspected Brugada Phenocopy Secondary to Coronary Slow Flow

Figure 1

There is the characteristic ST-segment in ≥1 right precordial leads (V₁ to V₃), following an -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 [3]. No high-pass filters were applied to attenuate low-frequency noise [15, 16]. (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).
