Diagnostic challenges: pseudo-phenomenon in Wolff-Parkinson-White syndrome

YS Sias, YT Wong, PG Kan

We reported two patients who presented with non-specific chest symptoms with ECG changes mimicking acute myocardial infarction and ventricular hypertrophy. Both of them were finally confirmed to have Wolff-Parkinson-White (WPW) syndrome after spontaneous resolution of the ECG changes. As a matter of fact, other differential diagnosis should be considered with respect to the ST-segment changes. Diagnostic pitfalls can be avoided by detailed analysis of the ECG before commencement of thrombolytic agents. (Hong Kong j.emerg.med. 2004;11:53-59)
