摘要:
A method and device for delivering ventricular resynchronization pacing therapy in conjunction with electrical stimulation of nerves which alter the activity of the autonomic nervous system is disclosed. Such therapies may be delivered by an implantable device and are useful in preventing the deleterious ventricular remodeling which occurs as a result of a heart attack or heart failure. The device may perform an assessment of cardiac function in order to individually modulate the delivery of the two types of therapy.

摘要:
Methods and devices for delivering cardiac therapy to a patient are provided. Various implantable device embodiments comprise a plurality of leads and a controller. The leads include at least one lead to be positioned within a lead path to deliver ventricular pacing pulses and to deliver neural stimulation at a site proximate to the heart to inhibit sympathetic nerve activity. The controller controls delivery of the ventricular pacing pulses in accordance with a programmed pacing mode and controls delivery of the neural stimulation. The controller is programmed to deliver remodeling control therapy (RCT) by delivering ventricular pacing to pre-excite a ventricular myocardium region to mechanically unload that region during systole, and further is programmed to deliver anti-remodeling therapy (ART) by delivering neural stimulation to inhibit sympathetic nerve activity in conjunction with RCT. Other embodiments are provided herein.

摘要:
An adherent patient device is configured to adhere to the skin of the patient and measure electrocardiogram data, impedance data, accelerometer data, blood oxygen data and temperature data. The adherent device can communicate wirelessly with gateways and a local processor system, such that the patient can wander about the hospital and update the monitoring station with the patient data when the patient is ambulatory. The local processor system can be configured to customize alerts for the patient, for example to notify automatically a specialist in response to a special condition of the patient. The adherent device may comprise a unique adherent device identifier such that the customized alert can be sent based on the unique device identifier. Each of the gateways can be carried and may comprise a unique gateway identifier, such that the unique device identifier and the unique gateway identifier can be used to locate the ambulatory patient.
摘要:
Systems and methods of detecting an impending cardiac decompensation of a patient measure an electrocardiogram signal of the patient. An incidence of cardiac arrhythmias is determined from the electrocardiogram signal. A risk of impending decompensation is determined in response to the incidence of cardiac arrhythmias. In many embodiments, the impending decompensation can be detected early enough to avoid, or at least delay, the impending decompensation, such that patient trauma and/or expensive ICU care can be avoided. Although embodiments make specific reference to monitoring electrocardiogram and other physiological signals with an adherent patch, the system methods and devices are applicable to many applications in which physiological monitoring is used, for example wireless physiological monitoring with implanted sensors for extended periods.
摘要:
An adherent device is configured to adhere to the skin of the patient with an adherent patch, for example breathable tape, coupled to at least four electrodes. The device comprises impedance circuitry coupled to the at least four electrodes and configured to measure respiration of the patient to detect sleep apnea and/or hypopnea. The impedance circuitry may be used to measure hydration of the patient. An accelerometer can be mechanically coupled to the adherent patch such that the accelerometer can be coupled to and move with the skin of the patient. Electrocardiogram circuitry to generate an electrocardiogram signal may be coupled to at least two of the at least four electrodes to detect the sleep apnea and/or hypopnea.
