Erroneous placement of fly leads inside an ECG machine caused diffuse Q-wave and T-wave inversion changes, leading to an inappropriate diagnosis of ischaemic heart disease in a young woman.
Case Report (n=1)
Clinicians should be aware that incorrectly aligned fly leads inside an ECG machine can cause artifactual ischemic changes, leading to misdiagnosis and unnecessary investigations.
We describe a case in which a young woman was inappropriately diagnosed as having ischaemic heart disease after presenting with exertional neck pain and an abnormal ECG. Diffuse Q-wave and T-wave inversion changes were later attributed to erroneous placement of fly leads inside the ECG machine at a recent service. Clinicians should be aware of this uncommon cause of incorrect lead connections, which can result in unnecessary investigations and treatment.
Butler et al. (Wed,) conducted a case report in Ischaemic heart disease (misdiagnosed) (n=1). Incorrectly aligned fly leads inside the ECG machine was evaluated on Diffuse Q-wave and T-wave inversion changes. Erroneous placement of fly leads inside an ECG machine caused diffuse Q-wave and T-wave inversion changes, leading to an inappropriate diagnosis of ischaemic heart disease in a young woman.
