摘要： A method comprising sensing a blood pressure signal, deriving a hemodynamic measure from the sensed blood pressure signal, adjusting an extra systolic stimulation control parameter in response to the hemodynamic measure, and delivering extra systolic stimulation pulses according to the adjusted control parameter. The sensed blood pressure signal may be a ventricular or arterial blood pressure signal from which an estimated cardiac output, end diastolic pressure, mean pressure or any other hemodynamic measure is derived. Adjusting the extra systolic stimulation control parameter may include adjusting a pacing rate, a pacing interval, an extra systolic stimulation ratio, an extra systolic stimulation interval or enabling or terminating the extra systolic stimulation.

摘要： Techniques for estimating the temporal refractory period of a heart, for adjusting a parameter for delivery of extra-systolic stimulation (ESS) therapy and for detecting an arrhythmia during delivery of ESS therapy are disclosed. In some embodiments, probe pulses are periodically delivered to estimate the location of the end boundary of the refractory period, and accordingly estimate its length. In some embodiments, the parameter is adjusted based on estimated length of the refractory period. For example, an extra-systolic interval (ESI) for delivery of ESS is adjusted to be a fixed interval longer than estimated lengths of the refractory period. In other embodiments, the parameter is adjusted based on a measured delay (or latency) between delivery of an ESS pulse and detection of an evoked response resulting from the pulse. In some embodiments, delays between delivery of an ESS pulse and detection of a subsequent depolarization are monitored to detect an arrhythmia.
摘要翻译：公开了用于估计心脏的时间不应期的技术，用于调整用于递送收缩期刺激（ESS）治疗的参数和用于在递送ESS治疗期间检测心律失常的技术。在一些实施例中，周期性地递送探针脉冲以估计不应期的末端边界的位置，并因此估计其长度。在一些实施例中，基于估计的不应期的长度来调整参数。例如，用于递送ESS的收缩期间期（ESI）被调整为比不应期的估计长度更长的固定间隔。在其他实施例中，基于在递送ESS脉冲和从脉冲产生的诱发响应的检测之间的测量延迟（或等待时间）来调整参数。在一些实施例中，监测递送ESS脉冲和随后去极化的检测之间的延迟以检测心律失常。

摘要： An extra-systolic stimulation (ESS) therapy addresses cardiac dysfunction including heart failure. ESS therapy employs atrial and/or ventricular extra-systoles via pacing-level stimulation to a heart. These extra-systoles must be timed correctly to achieve beneficial effects on myocardial mechanics (efficacy) while maintaining an extremely low level of risk of arrhythmia induction and excellent ICD-like arrhythmia sensing and detection (security). The present invention relates to therapy delivery guidance and options for improved ESS therapy delivery. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.

摘要： The present invention provides an apparatus and method for monitoring muscle function based on an index derived from a pressure or force signal. The muscle function index is derived from an instantaneous muscle stiffness ratio computed as the ratio of the first time derivative of the pressure or force waveform to the corresponding instantaneous pressure or force. The instantaneous stiffness ratio, {dot over (E)}/E(t), is in units of 1/sec and relates to the rate of strong bond formation and will be influenced by calcium handling properties of the muscle fibers and the intracellular calcium concentration. As such, an index derived from {dot over (E)}/E(t) provides a measure of the inotropic status of the muscle.

摘要： The present invention relates to the secure delivery of an extra-systolic stimulation (ESS) therapy to treat cardiac dysfunction that employs atrial and/or ventricular extra-systoles via pacing-like stimulation of the heart. These extra-systoles must be timed correctly to achieve beneficial effects on myocardial mechanics (benefit) while maintaining an extremely low level of risk of arrhythmia induction and excellent ICD-like arrhythmia sensing and detection (security). Further experience with ESS has led to improved implementation methods that depend on better blanking, ESS stimulation timing (of an “extra-systolic interval” or ESI), and ESS therapy delivery options and guidance. These methods may be employed individually or in combinations in an external or implantable ESS therapy delivery device.
