CONTACTLESS ELECTRIC CARDIOGRAM SYSTEM

A system for providing a standard electrocardiogram (ECG) signal for a human body using contactless ECG sensors for outputting to exiting medical equipment or for storage or viewing on a remote device. The system comprises a digital processing module (DPM) adapted to connect to an array of contactless ECG sensors provided in a fabric or the like. A selection mechanism is embedded into the DPM which allows the DPM to identify body parts using the ECG signals of the different ECG sensors and select for each body part the best sensor lead. The DPM may then produce the standard ECG signal using the selected ECG signals for the different body parts detected. The system is adapted to continuously re-examine the selection to ensure that the best leads are selected for a given body part following a movement of the body part, thereby, allowing for continuous and un-interrupted ECG monitoring of the patient.

11172819 · 2021-11-16 · ·

Multiple wireless sensor assemblies are individually attached to standard biopotential electrodes, which are placeable on a subject's body at locations for biopotential signal recording. The sensor assemblies, which are electrically isolated, simultaneously measure potential voltages from the body sites in accordance with a synchronization. The measured signals are amplified, digitized, and filtered, and then sent wirelessly to a monitoring system. The monitoring system receives multiple sensor signals and constructs biopotential vectors depending on the placement and number of the sensors. The sensor signals are referenced to a common virtual center bias to synthesize a common mode rejection.
