[Altered electrocardiogram during general anesthesia in a patient with intermittent Wolff-Parkinson-White conduction].
A delta wave, which had not been detected in the preoperative electrocardiogram (ECG), was observed just before induction of anesthesia in a 53-year-old male scheduled for partial pancreatectomy. His ECG, diagnosed as intermittent Wolff-Parkinson-White (WPW) conduction, varied markedly displaying different wide QRS complexes with a short PR interval, and then returned abruptly to normal during anesthesia. WPW syndrome belongs to the category of pre-excitation syndromes, which is characterized by the accelerated abnormal conduction to the ventricle and paroxysmal tachyarrhythmias caused by an accessory pathway. We should consider the influence of anesthesia-related agents on atrioventricular conduction, and aim at preventing and managing tachyarrhythmias caused by this syndrome.
