摘要： An implantable medical device applies an electric signal over two electrodes and measures the resulting electric signal over a candidate pair of neighboring electrodes on a lead for a first heart ventricle or over a candidate electrode of the lead and a case electrode. An impedance signal is determined for each candidate pair or electrode based on the applied signal and the measured resulting signal. A time difference between start of contraction in a second ventricle and the timing of local myocardial contraction as identified from the impedance signal at the site of the candidate pair or electrode is determined for each candidate pair or electrode. An optimal pacing electrode is selected to correspond to one of the electrodes of the candidate pair having the largest time difference or the candidate electrode having largest time difference.

摘要： A first ventricle is stimulated at a stimulation site, a point of time for arrival at the AV node for at least one depolarization wave resulting from the stimulation is estimated and a first activation time interval substantially corresponding to the time interval required for at least one depolarization wave to travel from the stimulation site in the first ventricle to the AV node is computed. A similar process is used to compute a second activation time interval for the other ventricle. Based on these activation time intervals and a difference between the intervals, a pacing therapy can be determined.

摘要： CRT settings for an implantable medical device are determined by applying pacing pulses to heart chambers of a scheme of different combinations of interchamber delays. A respective width parameter value representing an R or P wave width is determined for each such delay combination based on an ECG representing signal and the width parameter values are employed to estimate a parametric model defining the width parameter as a function of interchamber delays. Candidate interchamber delays that minimize the width parameter are determined from the parametric model and employed to determine optimal CRT settings. The technique provides an efficient way of finding optimal CRT settings when multiple pacing sites are available in a heart chamber.
摘要翻译：用于可植入医疗装置的CRT设置通过将不同组合的车间延迟的方案应用于心室来进行起搏脉冲来确定。基于ECG表示信号为每个这样的延迟组合确定表示R或P波宽的相应宽度参数值，并且使用宽度参数值来估计定义作为间歇延迟的函数的宽度参数的参数模型。从参数模型中确定最小化宽度参数的候选车间延迟，并用于确定最佳CRT设置。该技术提供了一种在心室中可用多个起搏部位时可以找到最佳CRT设置的有效方式。

摘要： An ischemia monitoring system has detectors for detecting the onset of an ischemic event of a tissue in subject, the end of the ischemic event and the end of a following recovery from the ischemic event, respectively. A time processor determines the duration of the ischemic event and the recovery period based on the detected onset and end times. A status processor co-processes the two determined time durations for the purpose of monitoring the ischemic status of the subject and detecting any deterioration in ischemic status for the latest ischemic event as compared to previous ischemic events that have occurred in the subject's tissue.

摘要： A biventricular cardiac stimulation device has a pulse generator for delivering stimulation pulses at least to the ventricles of a patient's heart. An evoked response detector has independent first and second ventricular sensing channels for ventricular evoked response detection in the ventricles. The pulse generator is controlled to deliver stimulation pulses to the second ventricle with a VV time delay after delivery of a stimulation pulse to the first-stimulated ventricle, the VV time delay being shorter than an evoked response detection time window that follows delivery of the stimulation pulse to the first-stimulated ventricle. An evoked response detector closes the evoked response detection window, or discards detections therein, in response to the emission of a stimulation pulse to the second-stimulated ventricle during the evoked response detection time window of the first-stimulated ventricle.
