Figure 1.

There is the characteristic ST-segment elevation ≥2 mm in ≥1 right precordial lead (V₁ to V₃), followed by an r'-wave and a straight ST-segment.

Notes: 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, the duration of QRS is longer than in a right bundle branch block and there is a mismatch between V₁ and V₆ (Figure 2)³. No high-pass filters were applied to attenuate low-frequency noise.¹⁴,¹⁵
