case_images: At admission, a 12-lead electrocardiogram (ECG) revealed a third degree sino-atrial block with bradycardia at 27 beats/min, enlargement of QRS with QT prolongation; ST segment and J point elevation in almost all leads: ST segment changes were convex upwards, camel saddle appearance evocative of Osborn waves (Figure 1).
