    • The invention provides methods and apparatus for determining in a non-tracking pacing mode (e.g., DDI/R, VVI/R) whether a ventricular pacing stimulus is capturing a paced ventricle, including some or all of the following aspects. For example, increasing a ventricular pacing rate a nominal amount to an overdrive pacing rate higher than a most recent heart rate and evaluating a conduction interval from a first pacing ventricle to a second sensing ventricle and then continuing to monitor the underlying rate to ensure that a threshold testing pacing rate will not exceed a predetermined minimum interval and providing pacing stimulation to the first ventricle and sensing the second ventricle to determine whether the pacing stimulation to the first ventricle was one of sub-threshold and supra-threshold. The methods and apparatus are especially useful in conjunction with ensuring actual delivery of a ventricular pacing regime (e.g., cardiac resynchronization therapy or "CRT").

    • According to some methods, for example, preprogrammed in a microprocessor element of an implantable cardiac pacing system, at least one of a number of periodic pacing threshold searches includes steps to reduce an evoked response amplitude threshold for evoked response signal detection. The reduction may be to a minimum value measurable above zero, for example, as determined by establishing a 'noise floor'. Alternately, amplitudes of test pacing pulses and corresponding post pulse signals are collected and reviewed to search for a break, to determine a lower value to which the evoked response threshold may be adjusted without detecting noise. Subsequent to reducing the threshold, if no evoked response signal is detected for a test pulse applied at or above a predetermined maximum desirable pulse energy, an operational pacing pulse energy is set to greater than or equal to the maximum desirable in conjunction with a reduction in pacing rate.
    • 根据一些方法,例如,在可植入心脏起搏系统的微处理器元件中预编程,多个周期性起搏阈值搜索中的至少一个包括减少诱发响应信号检测的诱发响应振幅阈值的步骤。 该减小可以是在零以上可测量的最小值,例如通过建立“本底噪声”确定的最小值。 或者,收集和检查测试起搏脉冲和对应的后脉冲信号的振幅以搜索中断,以确定可以在不检测噪声的情况下调整诱发响应阈值的较低值。 在降低阈值之后,如果对于在预定的最大期望脉冲能量之上或之上施加的测试脉冲没有检测到诱发响应信号,则可以将运行起搏脉冲能量设置为大于或等于期望的最大值, 起搏率

    • An implantable pacing system with single, double and triple chamber pacing capabilities, provided individually or in concert on a conditional or continuous basis depending upon ongoing analyses of atrial rhythm status, atrioventricular conduction status and ventricular rate. A mode is selected to reduce the occurrence of any ventricular pacing in favor of intrinsic atrioventricular and ventricular conduction. If excessively long PR intervals are occurring too frequently or atrioventricular conduction is unreliable or absent, the implantable pulse generator is operated in a conditional triple chamber pacing mode that provides atrial-synchronous biventricular pacing in every cardiac cycle for a period of time as necessary to restore and maintain AV synchrony, while minimizing ventricular asynchrony otherwise associated with monochamber RV pacing as in conventional dual chamber pacing systems. Similarly, biventricular pacing is provided in every cardiac cycle when ventricular rates are undesirably slow during atrial fibrillation, where AV synchronization is excluded.
    • 根据对心房心律状态,房室传导状态和心室率的持续分析,有条件或连续地单独或一起提供具有单室,双室和三室起搏能力的可植入起搏系统。 选择一种模式以减少任何心室起搏的发生,有利于固有的房室传导和心室传导。 如果过长的PR间期过于频繁地发生或者房室传导不可靠或不存在,则植入式脉冲发生器以有条件的三腔起搏模式运行,该模式在每个心动周期中提供心房同步双心室起搏一段时间以恢复所需的时间 并保持AV同步,同时最大限度地减少与单室RV起搏相关的心室不同步,正如常规双腔起搏系统一样。 类似地,当心室颤动期间心室率不合需要地缓慢时,在每个心动周期中提供双心室起搏,其中AV同步被排除。
