    摘要： A system and method for monitoring respiration including sensing a signal that varies with respiration, deriving a respiration parameter, applying criteria for detecting a respiration disturbance and determining one or more respiratory disturbance metrics. The system preferably includes an implantable sensor with an associated implantable medical device such that chronic respiration monitoring is possible. The implantable medical device may execute methods for detecting and measuring respiratory disturbances or may store data to be transferred to an external device for detecting and measuring respiratory disturbances. Respiratory disturbance detection may trigger a responsive action such as physiological data storage, a change in therapy delivery, or a clinician warning. Assessment of cardiac function may be made based on metrics of respiratory disturbances or a measure of circulatory delay time following detection of a respiratory disturbance.

    摘要： An atrial based pacing protocol promotes intrinsic conduction. An entire cardiac cycle is monitored for ventricular activity and permitted to lapse with ventricular activity. Ventricular pacing is available in a cardiac cycle immediately subsequent to such a skipped beat. When monitoring for intrinsic ventricular events, an event is expected within a given window. If no such event is detected, the cardiac cycle in truncated, leading to a shorter cycle that is devoid of ventricular activity. The subsequent cycle has a high likelihood of a ventricular sensed event and a greater than normal AV interval is provided prior to pacing.

    摘要： Assessing symptomatic and asymptomatic physiologic changes due to chronic heart failure involves apparatus and methods for gauging degradation and possible improvement using automated measurement of inter-ventricular conduction time, both alone and in combination with other automated physiologic tests. Conduction times increase due to the greater distance a wavefront must traverse as a heart enlarges. Analysis of conduction time can be used to verify the occurrence of cardiac remodeling due to heart failure as well as beneficial reverse remodeling due to successful heart failure therapy delivery. Patient activity level(s) and presence/increase in pulmonary fluids can also be used to automatically determine changes in heart failure status and/or predict hospitalization. Conduction time is monitored between electrodes positioned in the left and right ventricles of the heart via endocardial or epicardial electrodes.

    摘要： A medical device and associated method deliver cardiac pacing in a dual chamber pacing mode and schedule an atrial-ventricular (AV) conduction check during the dual chamber pacing mode to detect the presence of AV conduction. If AV conduction is detected during the scheduled AV conduction check, the medical device switches to an atrial pacing mode and switches back to the dual chamber pacing mode in response to an absence of AV conduction during the atrial pacing mode. The detected AV conduction is identified as a false positive detection in response to the pacing mode switch to the dual chamber pacing mode occurring within a predetermined interval of time from detecting the AV conduction.

    摘要： A medical device system determines and displays relative energy expenditure information for programmable parameter values. The system establishes a programmable parameter and multiple values of the parameter to be compared. A module performs a measurements for each of the multiple values and related to energy expenditure of a battery of an implantable medical device when operating according to each of the multiple parameter values. An energy expenditure for each of the values is computed using the measurements, and a graphical user interface is generated for displaying information corresponding to the computed energy expenditure for multiple parameter values.
