An ECG monitoring system for ambulatory patients includes a small multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. The processor also analyzes the received ECG signals for predefined arrhythmia. If an arrhythmia is detected, a wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a cellphone handset. The cellphone handset automatically relays the event information and ECG strip to a monitoring center for further diagnosis and necessary intervention.

Continuous outpatient ECG monitoring system

An ECG monitoring system for ambulatory patients includes a disposable multi-electrode patch that adhesively attaches to the chest of a patient. A reusable battery-powered ECG monitor clips onto the patch and receives patient electrical signals from the electrodes of the patch. A processor continuously processes received ECG signals and stores the signals in memory in the monitor. The processor also analyzes the received ECG signals for predefined arrhythmia. If an arrhythmia is detected, a bi-directional wireless transceiver in the ECG monitor transmits the event information and an ECG strip to a cellphone handset. The cellphone handset automatically relays the event information and ECG strip to a monitoring center for further diagnosis and necessary intervention.

A method for using a defibrillator is described which executes a resuscitation protocol having a CPR pause period. The defibrillator prompts a rescuer to perform CPR during a CPR pause period. The CPR pause period may be interrupted for the acquisition of ECG signal data which is not contaminated by chest compression artifacts. Following the acquisition of ECG signal data, the CPR period resumes and continues for its full period. The ECG signal data acquired during the interruption of the CPR period is analyzed and, if a shockable rhythm is identified, a shock sequence is initiated immediately upon conclusion of the CPR period.

A biomedical electrode patch having improved resistance to capacitive coupling to extraneous electric fields. The patch includes a conductive shield and a contact portion formed on an upper surface thereof. The contact portion extends through the film layer and contacts an electrode formed of a material suitable for conducting electrical signals from a patient. Conductive traces formed on the lower surface of the tab extend to contact pads. A nonconductive layer is printed over the traces and can have a shield formed thereon.

Shielded biomedical electrode patch

An ECG monitoring device comprises an integral handheld device including a ECG electronic module and an electrode patch having a plurality of electrodes which contact a subject by conductive hydrogel. A release liner covers and protects the hydrogel prior to use and is removed to expose the hydrogel. A second release liner is removed to expose a pressure sensitive adhesive by means of which the device is attached to a subject. The first and second release liners may be parts of a single release liner layer. After use the electrode patch is disposable and the ECG electronic module is detached from the patch for reuse.

Handheld, repositionable ECG detector

A training apparatus () for use with an external defibrillator is provided, the external defibrillator being responsive to a first electrode and a second electrode, including: a transparent layer having a first electrode attachment region defining an opening sized to receive the first electrode; a signal conductor disposed proximate the first electrode attachment region, the signal conductor having a transfer path, the transfer path operable to provide communication between the first electrode and the second electrode, when the first electrode and the second electrode are disposed on the training apparatus; and a two-dimensional representation of an anterior portion of a defibribation subject, identificable through the transparent layer, having the first electrode attachment region arranged thereon in a manner that defines a preferred plancement area of the first electrode on the defibrillation subject.

External defibrillator training apparatus and method

A method for operating an automatic external defibrillator (AED) prompts an operator about proper operation of the automatic external defibrillator and placement of the electrodes to ensure rapid and proper operation. Depending upon a state of a pad storage compartment, upon activation the AED issues an initial prompt, pauses after the initial prompt and then issues a second prompt. The AED also determines whether the pads have been removed from a liner and if so, issues a pad application prompt. The AED next determines whether both pads have been placed and if so, analyzes an impedance signal and if the impedance signal is erratic, issues a pad correction prompt. The AED also issues the pad correction prompt if the pads are removed from the liner but never go on the patient.

An electrode includes a conductive adhesive layer and a conductive foil layer having a void therein. One such electrode may be mounted in conjunction with another electrode upon a release liner having one or more openings therein to facilitate electrical signal exchange between electrodes. A release liner may include a moisture permeable and/or moisture absorbent membrane. A release liner may alternatively include a conductive backing layer. A release liner may also include an insulating swatch covering an opening. A release liner may be implemented as a foldable sheet, such that multiple electrodes may be mounted upon the same side of the foldable sheet. A medical device to which the mounted electrodes are coupled may characterize the electrical path between the electrodes. The medical device may perform a variety of electrical measurements, including real and/or complex impedance measurements. Based upon one or more measurements, the medical device may provide an indication of electrode condition, fitness for use, and/or an estimated remaining lifetime. An electrode condition indicator, which may form a portion of the medical device, may generate, present, or display electrode condition and/or estimated remaining lifetime information via a visual metaphor, such as a fuel gauge.

Method and apparatus for communicating the existence of an emergency situation without uniquely identifying the source of the communication

Handling or removal of a pair of pre-connected defibrillator electrode pads from their package, or a compartment in the defibrillator, is detected in order to effectively time the issuance of prompts to guide the user. Detection occurs when an impedance level between the electrode pads varies sufficiently over time to indicate occurrence of the handling or removal event. The pads are preferably configured to leverage variability in the impedance that results from bending of pads during handling or removal.
