Awareness of the problem of false electrocardiographic diagnosis of septal infarction due to cranially misplaced precordial leads V1 and V2, a common technical error, is important because this pseudo-pathologic finding can trigger unnecessary medical procedures and have other adverse sequelae. The non-trivial nature of this problem is emphasized by the case of a patient in whom the misdiagnosis caused loss of an employment opportunity. We demonstrate how P wave morphology in lead V2 can aid the clinician in suspecting erroneous right precordial lead placement in cases of apparent septal infarction. Ultimately, improved education of health care personnel regarding accurate precordial lead positioning technique is needed to minimize the occurrence of this electrocardiographic misdiagnosis.
由于颅顶导联 V1 和 V2 导致的室间隔梗死的心电图假阳性诊断问题，即一种常见的技术错误，应引起重视，因为这种假性病理发现可能会引发不必要的医疗程序和其他不良后果。由于一名患者因误诊而失去工作机会，这个问题的重要性就凸显出来了。我们展示了在疑似室间隔梗死的情况下，V2 导联的 P 波形态如何帮助临床医生怀疑错误的右胸导联放置。最终，需要通过提高医护人员对准确胸导联定位技术的认识，以尽量减少这种心电图误诊的发生。
