The present invention relates to the field of ambulatory and non-invasive monitoring of a plurality of physiological parameters of a monitored individual. The invention includes a physiological monitoring apparatus with an improved monitoring apparel worn by a monitored individual, the apparel having attached sensors for monitoring parameters reflecting pulmonary function, or parameters reflecting cardiac function, or parameters reflecting the function of other organ systems, and the apparel being designed and tailored to be comfortable during the individual's normal daily activities. The apparel is preferably also suitable for athletic activities. The sensors preferably include one or more ECG leads and one of more inductive plethysmographic sensor with conductive loops positioned closely to the individual to preferably monitor at least basic cardiac parameters, basic pulmonary parameters, or both. The monitoring apparatus also includes a unit for receiving data from the sensors, and for storing the data in a computer-readable medium. The invention also includes systems comprising a central data repository for receiving, storing, and processing data generated by a plurality of physiological monitored apparatus, and for making stored data available to the individual and to health care providers.

A method of analyzing the electrocardiogram ("ECG") using a set of vectors mathematically derived from the heart vector. The entire ECG waveform of one representative heartbeat is analyzed as a time series of vectors taken at selected time intervals. The vector set consists of the heart vector, the vector of deviation, vector of abnormality, delta vector, the delta vector deviation, and the delta vector abnormality. The analysis system can be applied to two or any greater number of ECG leads represented on planar axes, orthogonal spatial axes, or four or more axes in multidimensional space. The normal range of the ECG in this method is delineated by an adaptive multi-dimensional polyhedron in space to which the unknown ECG is compared. This is accomplished by utilizing a computer platform and the software program to support the required mathematical calculations.

ECG electrode includes at least one electrode configured to receive biopotential signals from a patient, a plug connector for connecting said ECG electrode assembly, a web, connected between the at least one electrode and the plug connector and configured to form an electrical connection therebetween. The lead set hub includes at least one receptacle configured to receive the plug connector of the ECG electrode assembly.

A device for epicardial support and / or the assuming of cardiac activity having a double membrane (1) consisting of an elastic inner membrane (2) and a non-expandable outer membrane (3) as well as a closed cavity (4) formed therebetween which can be inflated and deflated by means of a fluid. With the objective of further developing a device of the type as indicated at the outset which provides a simpler possibility of stimulating the heart in the critical post-operative phase, it is provided for at least one probe / electrode unit (7, 8) to be arranged on the inward facing side (6) of the inner membrane (2) to the heart (5) for epicardial ECG leads and / or signal transmission / conversion of an external pacemaker.

The invention is related to a device and method for cordless recording, telecommunication transmission, and processing of three special ECG leads by the means of the mobile device (1) and diagnostic-calibration center (2) where the reconstruction of standard ECG leads is performed. Reconstruction parameters are determined previously by calibration for each patient. In urgent situation, a patient (3) performs recording of three special ECG leads with the mobile device (1), and sends the memorized data to the diagnostic-calibration device (2) via a cellular telephone (4). The patient can trace the process of recording and sending the data with the help of sound and light indicators. Diagnostic-calibration center (2) is equipped with a PC computer (6) connected to a receiving cellular telephone (7) and calibration ECG device (8) with 14 electrodes. Ten electrodes are grouped into a standard 12-channel ECG cable, while the remaining four are used for recording of three special ECG leads and are grouped into a separate box (9) with integrated electrodes arranged identically as the integrated electrodes on the mobile device (1).

A patient monitor for determining a probability that a patient has acute cardiac ischemia including an input device connectable to a patient to acquire electrocardiogram (ECG) signals from the patient, an instrumentation amplifier connected to the input terminal to combine the signals and to generate at least one ECG lead, and an analysis module. The analysis module is operable to continuously read the ECG lead, to analyze a portion of the ECG lead for a period of time, and to calculate a probability that the patient has acute cardiac ischemia based at least in part on the analyzed portion of the ECG lead.

A system for wireless generation of at least one standard ECG lead comprises a plurality of electrodes for application to a subject at separate points thereof and a remote receiver station for generating at least one standard ECG lead from signals detected by a first group of said plurality of electrodes. The system further comprises a wireless sensing unit for generating at least two non-standard ECG signals from bipolar signals detected by a second group of the plurality of electrodes, a processor in the remote receiver station for calculation of a transform synthesizing each generated standard ECG lead from at least two of the non-standard ECG signals, a disconnection unit for disconnection of the first group of electrodes from the subject following the calculation, and a transfer unit for wireless transferring of the non-standard ECG signals to the remote receiver station following the disconnection of the first group of electrodes.

Disclosed is an ECG electrode lead wire connector which provides improved electrical and mechanical coupling of the ECG electrode press stud to the lead wire, provides enhanced ergonomics to the clinician, and may alleviate patient discomfort associated with the attachment and removal of ECG leads. The connector may be engaged and disengaged with little or no force imparted to the patient or the ECG pad, which significantly minimizes the risk of inadvertent dislodgement of the pad. In one embodiment the disclosed connector provides a thumb cam lever which affirmatively engages the press stud to the connector, and provides tactile feedback to the clinician that the connector is properly engaged. In other embodiments, the connector provides a pushbutton to enable the clinician to easily engage and disengage the connector from the ECG stud. The disclosed connectors may also decrease clinician fatigue, and may provide more reliable ECG results.

A medical device, such as an electrocardiogram (ECG) monitoring apparatus, provides galvanic isolation between low voltage electronics and a plurality of externally exposed ECG (patient contact) lead wires and electrodes. The ECG lead wires and / or electrodes can potentially make unwanted contact with sources of high voltage, such as from defibrillation pulses generated by defibrillation devices. The defibrillation pulses can cause damage to the low voltage electronics within the ECG monitoring apparatus. Electrical resistance is provided outside of the ECG lead wires and electrodes and separate from the low voltage electronics to protect against misdirection of a defibrillation pulse towards the low voltage electronics, and to protect against misdirection of a defibrillation pulse away from the patient for which the benefit of the defibrillation pulse is intended.
