A Subtle ECG Change Leading to Wolff-Parkinson-White Diagnosis Under General Anesthesia: A Case Report.

Wolff-Parkinson-White (WPW) syndrome is a congenital cardiac preexcitation syndrome that presents with an uninhibited electrical conduction between the atria and ventricles via an accessory pathway that has the potential for life-threatening arrhythmias. This is a case report of an asymptomatic/undiagnosed 43-year-old female with an incidental finding of WPW pattern during hardware removal surgery of the right hip while under general anesthesia. The identification of asymptomatic patients can be difficult because there may be only subtle changes on the electrocardiogram but could still pose as life-threatening in the presence of supraventricular tachycardia. Because of the potential risks, recommendations were given to follow up with the cardiology department to establish an accurate diagnosis. After recognition, the perioperative anesthetic goal was to prepare for any potential arrhythmia, minimize triggers, and provide proper follow-up so that appropriate testing could be conducted to properly diagnose and manage WPW.
