Fig 6.
Obese 30 year old heavy smoker with presumptive sleep apnÅa, asleep in CCU. His 12-lead ECG showed persistent T wave inversion in the anterolateral leads, but the coronary angiogram was normal. The strip shown below prompted a request for polysomnography which stated that the 2o AV block may have been caused by a spell of apnÅa. What do you think of this?
