RT Journal Article SR Electronic T1 An unusual case of misdiagnosed ventricular tachycardia JF Emergency Medicine Journal JO Emerg Med J FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 173 OP 174 DO 10.1136/emj.2007.050849 VO 25 IS 3 A1 C J Boos A1 M Y Khan A1 S Thorne YR 2008 UL http://emj.bmj.com/content/25/3/173.abstract AB We present the case of a 71-year-old man, with known Parkinson’s disease and previous coronary artery bypass surgery, who presented with acute chest pain. His initial 12 lead electrocardiogram (ECG) was unremarkable; however, a repeat 12 lead ECG during further chest pain suggested a ventricular tachycardia (VT) for which he was commenced on an intravenous amiodarone infusion. However, later analysis of his ECGs revealed that the apparent VT was, in fact, an artefact related to his parkinsonian tremor.
