Syncope refers to a sudden and transient loss of consciousness with postural failure due to the cerebral hypoperfusion. Transient loss of consciousness is a term used when the cause is not related to or unknown to the cerebral hypoperfusion. A 72-year-old female patient with hypertension was admitted for coronary artery bypass surgery. When the patient entered the operating room, the patient's blood pressure was 165/84 mmHg, Blood oxygen saturation (SpO2) was 97%, and the heart rate was 68 beats/min. While attaching the electrocardiogram, the patient complained of dizziness and then loss of consciousness all at once. The blood oxygen saturation reduced to 60%, and the bispectral index (BIS) was 40. At this time, the blood pressure was increased to 206/98 mmHg and the heart rate was 76 beats/min. Intubation was performed and neurologist was called up. After about 30 minutes, the consciousness was improved. Neurological examination showed no focal neurological signs. After a week, the patient finished the operation without any complications. In most cases, syncope is accompanied by hypotension and bradycardia. In this case, atypical forms of loss of consciousness that is slightly different from the typical type of syncope were observed.
