    摘要: Systems and methods using constant false alarm rate techniques for event detection. One example of an event detection method includes collecting a first distribution of measurements for a first physiological parameter. In another example, the first distribution of measurements includes only non-event measurements. One or more values are determined corresponding to at least a first tail area of the first distribution from at least one measurement of the first physiological parameter toward an end point of the distribution. A threshold is established based on a specified false alarm rate. The one or more values are compared to the threshold. The method includes determining if the measurement is representative of a detected event using the comparison.

    摘要: Systems and methods for cardiac contraction detection using information indicative of lead motion are described. In an example, an implantable medical device can include a receiver circuit configured to be electrically coupled to conductor comprising a portion of an implantable lead and be configured to obtain information indicative of a movement of the implantable lead due at least in part to a motion of a heart. The device can include a processor circuit configured to determine whether a cardiac mechanical contraction occurred during a specified interval included in the obtained information indicative of the movement of the implantable lead. The processor circuit can be configured to determine information about the cardiac mechanical contraction using the obtained information indicative of the movement of the implantable lead.

    摘要: An implantable device and method for monitoring S1 heart sounds with a remotely located accelerometer. The device includes a transducer that converts heart sounds into an electrical signal. A control circuit is coupled to the transducer. The control circuit is configured to receive the electrical signal, identify an S1 heart sound, and to convert the S1 heart sound into electrical information. The control circuit also generates morphological data from the electrical information. The morphological data relates to a hemodynamic metric, such as left ventricular contractility. A housing may enclose the control circuit. The housing defines a volume coextensive with an outer surface of the housing. The transducer is in or on the volume defined by the housing.

    摘要: A system and method provide heart sound tracking, including an input circuit, configured to receive heart sound information, and a heart sound recognition circuit. The heart sound recognition circuit can be coupled to the input circuit and can be configured to recognize, within a particular heart sound of a particular heart sound waveform, a first intra heart sound energy indication and a corresponding first intra heart sound time indication using the heart sound information from the particular heart sound waveform and the heart sound information from at least one other heart sound waveform. The particular heart sound can include at least a portion of one of S1, S2, S3, and S4. Further, the first intra heart sound energy indication and the corresponding first intra heart sound time indication can correspond to the at least a portion of one of S1, S2, S3, and S4, respectively.

    摘要: An embodiment uses an accelerometer to sense heart sounds, and determines heart rate info nation using the sensed heart sounds. An embodiment uses an accelerometer to sense respiratory activity. An embodiment delivers a programmed neural stimulation therapy with a programmed duty cycle, where the programmed duty cycle includes a stimulation ON portion followed by a stimulation OFF portion. An electrode electrically connected to the implanted neural stimulation device is used to remotely detect cardiac activity. The remotely detected cardiac activity is used to detect heart rate information during the stimulation ON portion and to detect heart rate information during the stimulation OFF portion. The detected heart rate information and/or the detected respiration information are used to control a neural stimulation therapy performed by the neural stimulator device and/or are used to provide diagnostic information for the patient's condition.
