Sudden Cardiac Death: The Most Feared but Potentially Preventable Presentation of Wolff-Parkinson-White Syndrome

Figure 3

Twelve-lead electrocardiogram after conversion to sinus rhythm (=baseline electrocardiogram). Shortened PR interval, delta wave, and secondary repolarization abnormalities are seen. This ECG is indicative of WPW syndrome, and a left anterolateral AP is suggested by negative QRS in V1 lead, QS complex in aVL lead, and positive delta wave in V3-V6 leads and inferior leads.
