    摘要: Provided herein are implantable systems, and methods for use therewith, for monitoring a patient's pre-ejection interval (PEI). A signal indicative of cardiac electrical activity and a signal indicative of changes in arterial blood volume are obtained. One or more predetermined features of the signal indicative of cardiac electrical activity and the signal indicative of changes in arterial blood volume are detected. The patient's PEI is determined by determining an interval between the predetermined feature of the signal indicative of cardiac electrical activity and the predetermined feature of the signal indicative of changes in arterial blood volume.

    摘要: Implanted systems and methods for monitoring a patient's arterial stiffness are provided. An implanted sensor is used to produce a signal indicative of changes in arterial blood volume for a plurality of beats of the patient's heart. A pulse duration metric is determined for each of a plurality of pulses of the signal, wherein each pulse of the signal corresponds to a beat of the patient's heart. Arterial stiffness is monitored based on the determined pulse duration metric for the plurality of pulses of the signal. This can include monitoring arterial stiffness based on a dispersion of the pulse duration metric and/or an average of the pulse duration metric.

    摘要: Techniques are provided for detecting stroke within a patient using an implantable medical device. In one example, various electrocardiac and physiological signals are sensed within the patient by the implantable device. The device derives a set of indices from the sensed signals based on parameters affected by stroke. Stroke is then detected within the patient based on an examination of the set of indices. Warnings can then be generated, neurostimulation delivered, pacing therapy adjusted, medications dispensed, etc., in response to the stroke. In one particular example, the set of indices includes: a heart rate variability index; a heart rate turbulence index; a baroreflex index; a QT index; a respiration index; and a circadian variability index, from which a composite stroke index is derived. Time delta indices may also be generated for each individual index, which are exploited in generating the composite stroke index.

    摘要: In a system and method for controlling an implantable stimulator capable of producing pacing pulses to be delivered to cardiac tissue, as well as vagal stimulation pulses to be delivered to vagus nerve sites, upon detection of a premature cardiac event, such as a premature ventricular or atrial contraction, a simulated heart rate turbulence (HRT) procedure is applied if the intrinsic heart rate turbulence is weakened or absent. The simulated HRT includes a first phase in which the heart rate is increased, from the existing level, for a number of heart beats, a second phase in which the heart rate is decreased for a number of heart beats, and an optional third phase in which the heart rate is returned to said existing level.
