case_images: The next day, electrocardiogram (ECG) detection showed tachycardia and second-degree atrioventricular block type I with an average heart rate of 93 beats/min, but with no sinus bradycardia event (Figure 2A). On day 87, the patient developed a substantial proportion of bradycardia below the focused level (heart rate <60 beats/min) and sinus arrest, with second-degree type II sinus atrial block with an average heart rate of 53 beats/min by the second ECG detection (Figure 2B). The next day, we rechecked the ECG and it showed continued sinus arrest with first-degree atrioventricular block with an average heart rate of 67 beats/min (Figure 2C). On day 106, sinus bradycardia disappeared but the atrioventricular conduction remained, showing prolonged PR and second-degree Mobitz type I blockage (Figure 2D). On day 175, the duration of sinus bradycardia was 17.1% of the total monitoring times, accompanied by intermittent first-degree atrioventricular block by dynamic ECG monitoring (Figure 2E). One week after escitalopram discontinuation, the last ECG showed the sinus rhythm with an average heart rate of 60 beats/min and first-degree atrioventricular block (Figure 2F).
