“…The resting electrocardiogram showed sinus rhythm, suspected ST segment elevation ≤0.05 mv in leads Ⅱ and aVF, frequent premature ventricular contractions, and negative troponin, myoglobin, and creatine kinase isoenzyme. On April 13, the patient's electrocardiogram showed: average heart rate: 79 beats/min, sinus rhythm, occasional atrial premature beats, frequent ventricular premature beats, ventricular premature beats: 10,229 beats, ST-T alteration, heart rate variability analysis: heart rate variability indices SDNN (50), SDANN (47), RMSSD (10), PNN50 (0) decreased (Figure 2). On April 14, liraglutide was stopped and insulin glulisine was given subcutaneously 6 U in the morning, 4 U in the evening and 4 U before meals.…”
