This tracing initially presents Q waves indicative of an inferior, posterior, and lateral myocardial infarction (MI). However, further analysis reveals that the Q waves are not due to actual infarction but rather a manifestation of Wolff-Parkinson-White (WPW) syndrome. The computer's ability to identify the activation pattern associated with WPW highlights the importance of understanding arrhythmias and their potential to mimic true myocardial damage on an electrocardiogram.

At first glance, this tracing shows Q waves of an inferior, posterior and lateral M.I. Happily, the computer recognized that the “infarcts” were due to WPW activation.
