    Abstract: A system for determining T wave bifurcation that includes three or more ECG leads configured to receive an ECG signal and a first computing device including a processor coupled to a memory, the processor and the memory configured to perform operations including: generating at least two orthogonal ECG vectors based on the ECG signal of a patient, processing the at least two orthogonal ECG vectors to determine a loop trajectory of at least a portion of the ECG signal, identifying a trajectory bifurcation by comparing the loop trajectory to a control loop trajectory for a plurality of cardiac cycles, and determining an indicator of a cardiac event based on the trajectory bifurcation.

    Abstract: An electrode assembly includes a first surface to be placed adjacent a person's skin and a second surface including a plurality of reservoirs of conductive gel. The plurality of reservoirs of conductive gel are disposed on sections of the electrode assembly that are at least partially physically separated and may move at least partially independently of one another to conform to contours of a body of a patient. The electrode assembly is configured to dispense an amount of the electrically conductive gel onto the first surface in response to an activation signal and to provide for a defibrillating shock to be applied to the patient through the amount of the electrically conductive gel.

    Abstract: An apparatus is described that includes a medical device including an output device, a memory, and a processor, electrodes configured to provide an electrical impedance signal to the processor, wherein the impedance signal corresponds to an impedance measured at a patient's chest, and sensors configured to provide a motion signal to the processor, wherein the motion signal is indicative of chest compressions performed during a cardiopulmonary resuscitation (CPR) treatment of the patient, wherein the processor is configured to receive the impedance signal and the motion signal and to execute instructions to determine threshold values of a signal processing algorithm for the impedance signal, adaptively modify the threshold values in response to motion signal changes, apply the modified threshold values to the impedance signal to identify airflow activities represented in the signal, calculate characteristics of the airflow activities, and provide an output indicative of the characteristics of the airflow activities.

    Abstract: An electrode for use with a therapeutic current delivery system can include a flexible, water vapor-permeable, conductive adhesive material; a current dispersing element in contact with the conductive adhesive material; and a non-conductive, flexible, water vapor-permeable, electrically-insulating top layer provided in contact with the current dispersing element. The current dispersing element can be conductive at least laterally along a plane of the electrode. The conductive adhesive material can be conductive in a direction substantially orthogonal to the plane of the electrode and semi-conductive in a direction substantially lateral to the plane of the electrode.
