  • Abstract
  • Look Inside

A 59-year-old man with obesity was admitted with nocturnal dyspnea and nocturnal precordial oppression. Catheter data disclosed no cardiac failure. Polysomno-graphy was performed for a total of 3 nights. The diagnosis of obstructive sleep apnea syndrome was made because apnea index was 50 times/hour in aver-age, the max apnea time was about 80 seconds anddisappearance of airflow during decrease of endoeso-phageal pressure was observed. At the max apnea time, ST-T change in leads V2-5 was observed with severe desaturation (arterial oxygen saturation: 49%).
