Breast Implants (BIs) in women are associated with several Electrocardiogram (ECG) modifications. However, the association between BIs and low-voltage ECG has not been reported yet. A 44-year-old woman with a history of breast implant surgery visited our outpatient cardiology clinic complaining of atypical chest pain. A standard ECG showed low voltage in all precordial and most of the limb leads. Physical examination and echocardiography showed no pathology. Nothing other than BIs was found as a cause of low-voltage ECG in the woman. Breast implant-induced ECG modification can mislead clinicians resulting in diagnostic challenges and unnecessary tests. Low-voltage ECG is one of the modifications associated with BIs, which has not been reported before. A large prospective study is required to investigate the impacts of BIs on ECG thoroughly.
