case_images: Twelve lead ECG on admission. The ECG displayed a sinus bradycardia with a heart rate of 52 beats per minute. The PR interval was short, measured at 100 milliseconds, accompanied by a delta wave. The QRS complex, with a duration of 126 milliseconds, exhibited a complete right bundle branch block pattern. The R-wave amplitude recorded in lead V5 was 6.62 mV, the Sokolow-Lyon index (S in V1 + R in V5) was also 6.62 mV. T-wave inversion and ST segment depression were noted in leads I, AVL, II, aVF, and V2-V6.
