摘要： Methods, systems and devices for providing cardiac resynchronization therapy (CRT) to a patient using a leadless cardiac pacemaker (LCP) and an extracardiac device (ED). The LCP is configured to deliver pacing therapy at a pacing interval. Illustratively, the ED may be configured to analyze the cardiac cycle including a portion preceding the pacing therapy delivery for one or several cardiac cycles, and determine whether an interval from the P-wave to the pace therapy in the cardiac cycle(s) is in a desired range. In an example, if the P-wave to pace interval is outside the desired range, the ED communicates to the LCP to adjust the pacing interval.

摘要： In embodiments, a wearable cardiac defibrillator system includes an energy storage module configured to store a charge. Two electrodes can be configured to be applied to respective locations of a patient. One or more reservoirs can store one or more conductive fluids. Respective fluid deploying mechanisms can be configured to cause the fluids to be released from one or more of the reservoirs, which decreases the impedance at the patient location, and decreases discomfort for the patient. In some embodiments an impedance is sensed between the two electrodes, and the stored charge is delivered when the sensed impedance meets a discharge condition. In some embodiments, different fluids are released for different patient treatments. In some embodiments, fluid release is controlled to be in at least two doses, with an intervening pause.

摘要： Embodiments of the invention include systems, protective casings for smartphones, and associated methods to enhance use of an automated external defibrillator (AED) device before arrival of emergency medical personnel. A system can include a smartphone and a protective casing abuttingly contacting one or more side portions of the smartphone and retaining the smartphone positioned therein. The smartphone can include a defibrillation control module to control defibrillation of a victim of sudden cardiac arrest. The protective casing can include sensors, capacitors, and extendable electrode pads. The protective casing further can include a check module to determine whether the victim's heart rhythm requires an electrical shock to reestablish a normal heart rhythm, a space module to measure presence and amount of preselected materials relatively near the system, and a shock module to activate the one or more capacitors and generate an electrical current to deliver an electrical shock to the victim's chest.

摘要： A modular medical system employing a bedside patient monitor (20), a portable patient monitor (40), a monitor docking station (50), a therapy applicator (30) and a therapy docking station (60). In operation, the portable patient monitor (40) is docked to the bedside patient via the monitor docking station (50) whereby the bedside patient monitor (20) and the portable patient monitor (40) measure patient parameters (e.g., ECG, Sp O2, pulse rate, NIBP, Et CO2, etc.) upon the portable patient monitor (40) being coupled to a patient. Alternatively, the portable patient monitor (40) is docked to the therapy applicator (30) via the therapy docking station (60) whereby the therapy applicator (30) conditionally delivers the electrical therapy (e.g., defibrillation shock, synchronized conversion, transcutaneous pacing, etc.) to the patient upon the portable patient monitor (40) being coupled to the patient.

摘要： In some examples, processing circuitry of a medical device system determines, for each of a plurality of periods, a plurality of heart rates of a patient based on a cardiac electrogram signal, and identifies a first subset of the plurality of heart rates as nighttime heart rates and a second subset of the plurality of heart rates as resting heart rates. The processing circuitry determines a representative nighttime heart rate based on the first subset of the plurality of heart rates, determines a representative resting heart rate based on the second subset of the plurality of heart rates, and determines a nocturnal dip base on the representative nighttime heart rate and the representative resting heart rate. The processing circuitry compares at least one of the representative nighttime heart rate, the representative resting heart rate, and the nocturnal dip in heart rate to a respective threshold value, and determines whether to generate an alert indicating a change in the cardiac function of the patient based on the comparison.

摘要： A medical device system, such as an extra-cardiovascular implantable cardioverter defibrillator ICD, senses R-waves from a first cardiac electrical signal by a first sensing channel and stores a time segment of a second cardiac electrical signal in response to each sensed R-wave. The medical device system determines a morphology parameter correlated to signal noise from time segments of the second cardiac electrical signal, detects a noisy signal segment based on the signal morphology parameter; and withholds detection of a tachyarrhythmia episode in response to detecting a threshold number of noisy signal segments.

摘要： A heart monitoring method is disclosed including an electroacoustic transducer such as an earphone coupled to a controller. The method proceeds with positioning a transducer in a person's ear in acoustic communication with the tympanum. Signals from the transducer are processed to determine the presence of pulsatile blood flow. The heart monitor may be incorporated into a portable media playback device alternating between playback and monitoring mode or performing both simultaneously using one earphone for each function. The heart monitor may be incorporated into a defibrillator to sense the presence of blood flow for use in a shock delivery decision.

摘要： An emergency medical device (20) (e.g., an external defibrillator/monitor) employing an emergency medical subsystem (21) for executing an emergency medical procedure (e.g., a monitoring subsystem (21) and a therapy subsystem (21)), and an emergency medical controller (23) for controlling an activation of the emergency medical subsystem (21). The subsystem (21) includes one or more operational components (22). In operation, the controller (23) conditionally actuates a device readiness indicator (24) (e.g., auditory or visual) indicative of an operational readiness of the operational component(s) (22), and conditionally actuates a failure warning indicator (25) (e.g., auditory or visual) indicative of a pending failure of the operational readiness of the operational component(s) (22). The failure warning indicator (25) may be actuated based on a predictive failure analysis of a premature degradation of the operational component(s) (22), a repeated occurrence of error conditions of the operational component(s) (22) (particularly recoverable error conditions), and a shortened reliable life of the operational component(s) (22).
