An electrocardiogram sensor (400) is provided, comprising an electrode array (100), comprising a substrate (102) interconnecting three or more spaced apart electrodes (101a-c); and a flexible sheet (200) having a greater areal extent than that of the electrode array (100). The flexible sheet (200) is configured to secure the electrodes (101a-c) to the body of a subject.

The present system allows for the physician to change the relative height of the signal to allow for examination of details of the signals, while maintaining an ability to interpret signal voltage levels absolutely based on color or other secondary mechanism beyond signal height. The disclosed system and method provide for faster and more accurate analysis based upon the color of the signal. The signal height may change, such as to view, display, or examine details of the signal, while the colors of the display do not. The color scale of the signal provides an absolute scaling of the signal regardless of the displayed height.

The invention provides a body-worn monitor that measures a patient's vital signs (e.g. blood pressure, SpO2, heart rate, respiratory rate, and temperature) while simultaneously characterizing their activity state (e.g. resting, walking, convulsing, falling). The body-worn monitor processes this information to minimize corruption of the vital signs by motion-related artifacts. A software framework generates alarms/alerts based on threshold values that are either preset or determined in real time. The framework additionally includes a series of heuristic rules that take the patient's activity state and motion into account, and process the vital signs accordingly. These rules, for example, indicate that a walking patient is likely breathing and has a regular heart rate, even if their motion-corrupted vital signs suggest otherwise.

A method including obtaining a first electrocardiography [ECG] reading from a test subject when the test subject is believed to not suffer from blood volume loss and obtaining a second ECG reading from the test subject when the test subject is in an unknown condition regarding blood volume loss. The first ECG reading and the second ECG reading are obtained using the same electrode positions on the test subject and include sets of ECG signals which, based on experimental data, respond to small decrease in blood volume by a statistically significant strength decrease. If the second ECG reading exhibits a statistically significant strength decrease compared with the first ECG reading, an alert condition is raised, which indicates potential small decrease in blood volume. The method can be embodied as a stand-alone ECG apparatus or as an add-on unit to an ECG apparatus.

A wearable device and respiration sensing module are provided. The wearable device includes a first respiration sensing module and a second respiration sensing module. The first respiration sensing module is configured to sensing respiration of a user to obtain a first respiration information. The second respiration sensing module is configured to sensing respiration of the user to obtain a second respiration information. The second respiration sensing module includes a substrate, a first electrode, a second electrode and a stretchable conductive element. The first electrode and the second electrode are disposed on a first surface of the substrate. The stretchable conductive element is physically and electrically connected between the first electrode and the second electrode. The respiration of the user is judged according to the first respiration information and the second respiration information.

An electrocardiogram (ECG) measurement device for a vehicle is provided. The ECG measurement device includes an impedance compensator that corresponds to an electrode in contact with a body of a driver and configured to compensate an impedance of each of electrode signals received from the electrode. An electrode selector sequentially selects the electrode signals in response to receiving the electrode signals from the electrode. A differential amplifier differentially amplifies the electrode signals. In particular, each electrode signal has the compensated impedance. Additionally, a signal quality evaluator evaluates quality of an ECG signal output from the differential amplifier and a compensation controller then adjusts an impedance compensation value of each of the impedance compensators as a result of evaluating the quality of the ECG signal.
