  • Title: [Pseudo Q waves in myocardial necrosis: a pitfall with a Wolff-Parkinson-White appearance].
    Author: Perrenoud JJ, Adamec R, Righetti A.
    Journal: Arch Mal Coeur Vaiss; 1980 Nov; 73(11):1279-86. PubMed ID: 6778423.
    Abstract:
    The diagnosis of inferior myocardial infarction was wrongly made in a patient with a history of chest pain and Q waves in Leads 3 and aVF. Despite a normal PR interval, ventricular preexcitation was suspected on the deformation of the upstroke of the QRS complex, suggestive of a delta wave. Ventricular and coronary angiography and exercise Thallium 201 myocardial scintigraphy allowed the diagnosis of myocardial infarction to be eliminated. Endocavitary electrophysiological recordings confirmed the presence of an accessory atrioventricular conduction pathway (Kent bundle) and explained the intermittent appearances of the WPW syndrome on ECG. The patient was investigated after the acute episode, and the absence of cardiac enzyme estimations at that time made the rectification of the diagnosis more difficult.
