摘要： In bi-ventricular pacing devices (including CRT devices) analysis of myocardial electrogram signals in one ventricle (e.g., a left ventricle, or “LV”) can same ventricle, on a continuous (every pacing cycle), triggered, aperiodic and/or periodic basis. Rather than using an evoked-response principle as has been the basis of capture detection in prior art and other systems, a principle employed via the present invention uses evidence of inter-ventricular conduction (i.e., from the opposite chamber) and/or atrio-ventricular conduction as evidence of LOC, since a non-capturing pacing stimulus provided to a first chamber will allow the myocardial tissue of the first chamber to remain non-refractory and thus inter-ventricular and atrio-ventricular wavefront propagation and conduction can commence and be detected thereby revealing whether LOC has occurred.
摘要翻译：在双心室起搏装置（包括CRT装置）中，在一个心室（例如，左心室或“LV”）的心肌电图信号的分析可以在连续的（每个起搏周期）上相同的心室触发，非周期性和/或定期的基础。而不是使用诱发反应原理作为现有技术和其他系统中的捕获检测的基础，通过本发明采用的原理使用心室间传导（即，从相对的室）和/或心室传导的证据，心室传导作为LOC的证据，因为提供给第一腔室的非捕获起搏刺激将允许第一腔室的心肌组织保持不耐受，因此可以开始心室间和心室内波前传播和传导检测出来是否显示LOC是否发生。

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.
摘要翻译：评估因慢性心力衰竭引起的症状和无症状的生理变化涉及用于测量降解的设备和方法，并且可以通过自动测量心室间传导时间来单独测量并与其他自动化生理测试结合使用。由于随着心脏的扩大，波前必须穿越的距离越大，传导时间就会增加。传导时间分析可以用于验证由于心力衰竭导致的心脏重构的发生以及由于成功的心力衰竭治疗递送而导致的有益的反向重建。患者活动水平和肺流体的存在/增加也可以用于自动确定心力衰竭状态的变化和/或预测住院治疗。通过心内膜或心外膜电极监测位于心脏左心室和右心室的电极之间的传导时间。

The parameters are used in conjunction with protocol for minimizing or reducing ventricular pacing, wherein ignoring intrinsic ventricular events during the blanking period might otherwise affect the performance of the protocol.

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.
摘要翻译：医疗设备和相关方法在双室起搏模式下提供心脏起搏，并且在双室起搏模式期间安排心房（AV）导通检查以检测AV传导的存在。如果在预定的AV导通检查期间检测到AV传导，则医疗设备切换到心房起搏模式并且响应于在心房起搏模式期间不存在AV传导而切换回双室起搏模式。检测到的AV导通被识别为响应于从检测AV传导而在预定时间间隔内发生的双室起搏模式的起搏模式切换的假阳性检测。
