question

A 52-year-old man comes to the physician with his wife because of a 1-year history of excessive daytime sleepiness. He does not think the symptoms are problematic, but his wife is concerned because he sometimes falls asleep on the sofa early in the evening when guests are present. He also once fell asleep while driving at night and drove off the road, narrowly avoiding injury. His wife says that he has always snored loudly, and over the past year, he has had episodes of choking or gasping for breath while sleeping. He is 178 cm (5 ft 10 in) tall and weighs 105 kg (231 lb); BMI is 33 kg/m2 . His pulse is 76/min, respirations are 14/min, and blood pressure is 150/76 mm Hg. Physical and neurologic examinations show no other abnormalities. Which of the following is most likely to confirm the diagnosis?

choices

  1. 24-Hour ambulatory ECG monitoring
  2. Multiple sleep latency test
  3. Polysomnography
  4. CT scan of the head
