title: Offset electrocardiographic electrode simulating a pulmonary nodule on radiographs.
abstract: A recently developed type of electrocardiographic (ECG) monitoring electrode may simulate a pulmonary nodule on chest radiographs. The artifact results from the offset design of the electrode, which contrasts with the configuration of conventional electrodes. Awareness of this potential artifact is important to prevent misdiagnosis.
