BACKGROUND We evaluated brain tissue oxygen pressure (PO2), carbon dioxide pressure (PCO2) and pH during ischemia with brain temperature at 35 degrees and 18 degrees C in the same patient. METHODS Surgery was performed in a 60-year-old woman to clip a large aneurysm in the left internal carotid artery (ICA). A Paratrend 7 probe measuring PO2, PCO2, and pH(More)

A case is presented in which left anterior hemiblock obscured totally the diagnosis of right bundle branch block by abolishing the S wave in leads 1 and aVL, and terminal R wave in leads V1 and V2. The presence of right bundle branch block was confirmed by recording high V1 and V2 leads. Subsequently, the ECG revealed how a greater degree of conduction(More)
