case_images: Twelve-lead electrocardiogram (ECG) reported sinus bradycardia with a rate of 56 beats per minute, normal axis of deviation, PR interval of 128 ms (normal = 120-200 ms), QRS complex duration of 98 ms (normal = 80-100 ms), QTC interval of 370 ms (normal <= 440 ms), and diffuse ST segment elevation throughout (Figure 1).
