His initial electrocardiogram revealed P waves in lead V<jats:sub>1<\/jats:sub> that led to a diagnosis of supraventricular tachycardia. Subsequently, during an electrophysiology study, the tachycardia was reproduced and documented to be ventricular in origin. The P waves seen were actually part of the QRS complex and therefore pseudo P waves. The correct diagnosis of the arrhythmia allowed for more appropriate therapy for the patient. This case illustrates that pseudo P waves may be present on the surface electrocardiogram and confuse the diagnosis of wide QRS tachycardia.<\/jats:p>","DOI":"10.1002\/clc.4960090107","type":"journal-article","created":{"date-parts":[[2009,2,7]],"date-time":"2009-02-07T02:09:15Z","timestamp":1233972555000},"page":"30-32","source":"Crossref","is-referenced-by-count":3,"title":["Pseudo P waves: A cause of diagnostic confusion in wide QRS tachycardia"],"prefix":"10.1002","volume":"9","author":[{"given":"P.
