    摘要: An implantable pacing device for delivering ventricular pacing may be configured to intermittently reduce the AVD interval for beneficial effect in patients with compromised ventricular function (e.g., HF patients and post-MI patients). The AVD interval may be reduced in an AVD reduction mode, by shortening the AVD in an atrial triggered ventricular pacing mode or by switching to a non-atrial triggered ventricular pacing mode (e.g., VVI) and delivering paces at a rate above the intrinsic rate. The physiological effects of AVD reduction may be either positive or negative on cardiac output, depending upon the individual patient.

    摘要: Electrodes of a subcutaneous monitoring system receive body electrical signals that indicate both cardiac and non-cardiac muscle activity. In general, non-cardiac muscle activity is often correlated with physical activity, and physical activity is typically a strong indicator of patient health. Exemplary systems and methods that detect non-cardiac muscle activity information in sensed body electrical waveforms may provide a diagnostic tool for monitoring physical activity level over time in patients that have subcutaneous monitoring systems. In an illustrative embodiment, systems and methods for presenting patient activity information in a graphical format over intervals of time include processing ECG waveform information to identify and to accumulate non-cardiac muscular activity information during each of the intervals of time. In various implementations, number, intensity, and/or duration of the events that are identified during a time interval may be accumulated and stored for subsequent recall.

    摘要: A system is provided for obtaining and analyzing biological data of a subject. The system includes a biological data recording device that can sense biological signals of a subject over time and record the sensed biological signals as biological data. The system also includes an event time recording device that is physically separate from, and does not communicate with, the biological data recording device. The event time recording device includes a user actuatable component, and also includes a recording component that records user actuation data, which includes a time stamp indication as to when any instances of user actuation occurred. The system also includes equipment that can periodically receive the recorded biological data from the biological data recording device and the user actuation data from the event time recording device, and can correlate the biological data and the user actuation data to generate correlated biological data.

    摘要: An implantable medical device includes a voltage measurement circuit to measure a potential difference between implanted electrodes in a thorax of a living being, the potential difference resulting from an electrical P-wave cardiac signal. The implantable medical device also includes a processing unit to calculate a vector corresponding to the P-wave cardiac signal, the vector comprising a magnitude and a direction, and derived from measured potential differences and orientations defined by locations of the implanted electrodes. The implantable medical device further includes a monitoring unit to track a rotation of the vector corresponding to the P-wave cardiac signal. In various implementations, the monitoring unit may use the rotation to detect an inter-atrial block condition.

    摘要: A sensor is located within the body of a subject, such as for capturing pacing pulses transmitted as part of cardiac therapy from an implanted cardiac function management device. Counted pulses may be used to derive the onset of pulmonary edema within the body through pulse characteristics such as frequency and amplitude. The sensor may be anchored within mediastinal pleura or the airway of the body with the ability to communicate wirelessly to one or more other medical devices, such as an implanted cardiac function management device. It may also adjust transmission of the communication to discriminate among multiple sensors. Methods of use are also described.

    摘要: An amount of fluid in a thoracic or other region of a subject may be monitored by internally injecting an electrical energy stimulus (e.g., constant voltage source) through the region, detecting voltage resulting from the electrical energy stimulus, and calculating a fluid volume indicative signal. The injected energy stimulus creates a first lead field. The responsive voltage is detected using an electrode configuration that defines a second lead field, which is arranged in a negative sensitivity configuration with respect to the first lead field at the region being monitored.

    摘要: This patent document describes, among other things, systems and methods for monitoring lung fluid status, such as monitoring the presence or absence of pulmonary edema, in a subject using information about the cardiac impedance-indicating component of a measured impedance-indicating signal. In various examples, an amplitude or contribution change over multiple cardiac cycles of the cardiac impedance-indicating component is used to compute and provide a lung status indication. In various examples, a decreasing amplitude or contribution trend of the cardiac impedance-indicating component signifies an increasing amount of fluid in the subject's lungs, as a greater portion of an injected thoracic impedance measurement current formerly traversing the heart is rerouted through the lung due to the less resistance path created by the fluid accumulation therein. In another example, measurements of the impedance-indicating signal, and thus the cardiac impedance-indicating component, are taken at one or a combination of end-inspiration or end-expiration.
