Abstract
An electrocardiogram detection device whose housing may be made of a conductive material, and the electrocardiogram detection device may include a voltage holder circuit configured to provide a target potential for the housing. A potential difference between the target potential provided by the voltage holder circuit and a reference potential provided by an electrocardiogram detection circuit for a third electrode is small. Therefore, in an ECG detection process, even if a user accidentally touches the housing and causes the housing to be conducted to the third electrode, no leakage current is generated between the housing and the third electrode, or a small leakage current is generated between the housing and the third electrode. This can effectively reduce interference to an ECG signal and ensure accuracy of ECG detection.
