摘要： In general, the disclosure describes techniques for detecting lead related conditions, such as lead fractures or other lead integrity issues. As described herein, delivering an electrical signal through selected electrodes may result in, reveal, or amplify noise if a lead related condition is present. A processor may detect electrical noise indicative of the lead related condition subsequent to the delivery of the electrical signal, and identify a lead related condition in response to detecting the noise.

摘要： Techniques for diagnosing lead fractures and lead connection problems are described. One or more medical leads may be coupled to an implantable medical device (IMD) to position electrodes or other sensors at different locations within a patient than the IMD. The IMD may include a lead diagnostic module configured to diagnose problems with a coupled lead and automatically select between a lead fracture problem and a lead connection problem based on the diagnosis. The diagnosis of either lead fracture problems or lead connection problems may be based on a timing of an increased impedance value with respect to connection of the lead to the IMD, a return to baseline impedance values after the increased impedance value, an abrupt rise of the increased impedance value, maximum impedance values, or oversensing. An external device may present the diagnosis to a user to facilitate appropriate corrective action.
摘要翻译：描述了用于诊断铅骨折和铅连接问题的技术。可以将一个或多个医疗引线耦合到可植入医疗装置（IMD）以将电极或其他传感器定位在患者内的不同于IMD的位置。 IMD可以包括引导诊断模块，其被配置为诊断耦合引线的问题，并且基于诊断自动选择引线断裂问题和引线连接问题。铅断裂问题或引线连接问题的诊断可能是基于相对于引线与IMD的连接的增加的阻抗值的时序，在增加的阻抗值之后返回到基线阻抗值，突然上升增加的阻抗值，最大阻抗值或过强。外部设备可以向用户呈现诊断以促进适当的校正动作。

摘要： Implantable medical device for determination of timing for electrical shocks to the heart to determine shock strength necessary to defibrillate a fibrillating heart. The timing corresponds the window of most vulnerability in the heart, which occurs during the T-wave of a heartbeat. Using a derivatized T-wave representation, the timing of most vulnerability is determined by a center of the area method, peak amplitude method, width method, or other similar methods.

摘要： A method and apparatus for validating cardiac pacing pulse train preceding a T- shock. Validation of the pacing pulse train includes verifying capture of at least the last pacing pulse of the pulse train and verifying that intrinsic ventricular events are not sensed during a pacing train interval that includes at least the interval between the last pacing pulse and a scheduled T-shock delivery. Capture verification may include sensing an event during an ER (evoced response) sensing window, morphological analysis of a sensed event, and analysis of the temporal relationship between sensed events occurring on different EGM sources. The scheduled T-shock is delivered in response to a valid pacing pulse train. A response to an invalid pacing pulse train may include any of an invalid pacing train notification, withholding a scheduled T-shock, extension of the pacing train, repeating the pacing train, or adjusting the pacing pulse train parameters.
