A system and method for monitoring vital signs and capturing data from a patient remotely using radiotelemetry techniques. The system is characterized by a cordless, disposable sensor band with sensors form measuring full waveform ECG, full waveform respiration, skin temperature, and motion, and transmission circuitry for the detection and transmission of vital signs data of the patient. A small signal transfer unit that can either be worn by the patient, e.g., on his or her belt, or positioned nearby receives data from the sensor band, which it then forwards by e.g., radio transmission to a base station that can be located up to 60 meters away. The base station receives data transmissions from the signal transfer unit and is designed to connect to conventional phone lines for transferring the collected data to a remote monitoring station. The base station may also capture additional clinical data, such as blood pressure data, and to perform data checks. Patient safety is enhanced by the ability of the base station to compare clinical data, e.g., ECG, against given profiles and to mark events when appropriate or when the base station is programmed to do so. Such events are indicated to the physician and could be indicated to the patient by reverse transmission to the signal transfer unit. A remote monitoring station allows the presentation and review of data (including events) forwarded by the sensor band. ECG analysis software and a user-friendly graphical user interface are provided to remotely analyze the transmitted data and to permit system maintenance and upkeep. The system of the invention has useful application to the collection of patient clinical data during drug trials and medical testing for regulatory approvals as well as management of patients with chronic diseases.

A system and method for monitoring health parameters and capturing data from a subject.
