摘要： A method for diagnosing an implantable cardiac device including a plurality of implanted leads may include: monitoring a plurality of parameters associated with the plurality of implanted leads; detecting a change in one of the parameters; evaluating at least one of the other parameters upon detection of the change; and diagnosing a problem with the implantable cardiac device based on the detected change and the evaluation. A system for diagnosing an implantable cardiac device including a plurality of implanted leads may include an implantable pacing device and a processor. The processor may be configured to: monitor a plurality of parameters associated with the plurality of implanted leads; detect a change in one of the parameters; evaluating at least one of the other parameters upon detection of the change; and diagnose a problem with the implantable cardiac device based on the detected change and the evaluation.

摘要： An implantable medical device includes leads having electrodes that are positioned within a heart. The electrodes sense signals derived from the heart that include waveform segments. The device includes a timing module that determines when the waveform segments cross a threshold and measures time intervals between at least two threshold crossings by the waveform segments. The device also includes event identification module that compares the time intervals to a predetermined pattern associated with a cardiac event. The event identification module identifies the cardiac event based on the time intervals and the predetermined pattern.

摘要： Techniques are described for discriminating ventricular tachycardia (VT) from supraventricular tachycardia (SVT) using an implantable medical device capable of multi-site ventricular sensing. In one example, ventricular depolarization events are detected within a patient by the implantable device during a tachyarrhythmia, at both a left ventricular sensing site and a right ventricular sensing site. Ventricular event timing differences are then ascertained. The device compares the ventricular event timing differences detected during the tachyarrhythmia with predetermined supraventricular event timing differences for the patient, such as event timing differences previously detected within the patient during sinus rhythm or extrapolated from sinus rhythm values. The device then distinguishes VT from SVT based on the comparison of the event timing differences detected during the tachyarrhythmia with the predetermined supraventricular event timing differences. Morphological waveform analysis can also be performed, when needed, to further distinguish VT from SVT.
摘要翻译：描述了使用能够进行多部位心室感测的可植入医疗装置来区分室上性心动过速（VT）与室上性心动过速（SVT）的技术。在一个示例中，在左心室感觉部位和右心室感测部位的快速性心律失常期间，可植入装置在患者体内检测心室去极化事件。然后确定心室事件时间差异。该装置将在快速性心律失常期间检测到的心室事件时间差与患者的预定的室上事件时间差相比较，例如在窦性心律期间先前在患者内检测到的事件时间差异或从窦性心律值外推。然后，该设备基于在快速性心律失常期间检测到的事件时间差与预定的室上事件时间差异的比较来区分VT与SVT。当需要时也可以进行形态波形分析，以进一步区分VT与SVT。
