Abstract
A wireless electrocardiogram (ECG) system is disclosed. The wireless ECG provides for recording potentials on the surface of a body. The wireless ECG includes a plurality of electrodes suitable for attachment to the surface of the body, a voltage measuring circuit for detecting a voltage between a reference voltage level and electrodes, an error detecting circuit, and a transmitting circuit for transmitting the detected voltage signal to a receiver. The disclosed system is robust in that it provides the capability of continuous monitoring of a subject while correcting for defects in an electrode, contact, presence of excessive noise or other developments in addition to providing the customary alarms in the event of disruptions.
