摘要： Systems and methods for detecting and measuring cardiac contractile function of a heart using an acceleration sensor unit inserted within the heart, such as within a vein of the cardiac wall are disclosed. The systems and methods involve detecting the occurrence of electrical events within the patient's heart by inserting and positioning an implantable lead having an electrode near a cardiac wall as well as detecting mechanical events within the patient's heart by then inserting and positioning a cardiac motion sensor unit through the inner lumen of the implantable lead. Furthermore, the systems and methods do not require dedicated leads and may be used with preexisting implantable leads.

The implantable system includes a sensor for generating sensed signals representing detected heart sounds, an interface circuit and a control circuit for receiving the sensed signals, generating data representing the heart sounds therefrom, and transmitting the data to the external system via the interface circuit. The external system includes an interface circuit for communicating with the implantable system, and a control circuit for receiving the data representing the heart sounds and for generating control signals that cause an output device to generate outputs representing the sounds. The implantable system may also include a sensor(s) for detecting cardiac electrical signals. In this case, outputs representing the cardiac electrical signals are also output.

摘要： A system, method, or device classifies an arrhythmia according to the temporal order in which a depolarization wave associated with a particular heart contraction is received at a plurality of electrodes. One or more antiarrhythmia therapies is mapped to each arrhythmia classification. When a particularly classified arrhythmia is detected, the correspondingly mapped therapy list is selected and an appropriate antiarrhythmia therapy delivered. In one example, the particular therapy delivered in response to an arrhythmia depends at least in part on its historical success in treating arrhythmias of that classification.

摘要： An implantable cardiac rhythm management device capable of automatically detecting intrinsic and evoked response of a patient's heart and suitable for use during capture verification. The device of the present invention may operate in an automatic capture verification mode, wherein an electrocardiogram signal of a patient's heart is received and used by the device to determine whether a stimulation pulse evokes a response by the patient's heart. The device suspends the automatic capture verification mode and/or adjust the detection threshold dependent upon detected and/or measured noise, a determined amplitude of evoked response, a determined modulation in the evoked response, or detected and/or measured artifact. Further, the sensing circuit of the rhythm management device of the present invention reduces afterpotentials that result due to delivery of the stimulation pulses.

摘要： A method for reducing the affects of intrinsic detection latency in a cardiac rhythm management device, wherein said method is initiated immediately prior to delivering a stimulation pulse to the heart tissue. A coincidence of intrinsic and cardiac rhythm management initiated stimulus or the delivery of a stimulation pulse proximate the time of an intrinsic event due to intrinsic detection latency may results in delivery of unnecessary backup stimulus and/or imprecise determination of a pacing threshold. When stimulating the heart, the timing sequence for delivering a stimulation pulse typically depends upon the timing of a previous intrinsic or device initiated event. Further, the method of the present invention reduces the affects of intrinsic detection latency thereby facilitating improved detection of capture and determination of capture threshold for minimizing power consumption while assuring therapeutic efficacy.
摘要翻译：一种减轻心律管理装置中内在检测延迟的影响的方法，其中所述方法在将刺激脉冲传递到心脏组织之前立即开始。由于内在的检测潜伏期，固有和心律管理发起的刺激或接近内在事件时间的刺激脉冲的传递的巧合可能导致递送不必要的备份刺激和/或不精确地确定起搏阈值。当刺激心脏时，用于递送刺激脉冲的定时序列通常取决于先前的固有或设备启动事件的时序。此外，本发明的方法减少了内在检测潜能的影响，从而有助于提高捕获捕获阈值的检测和捕获阈值的确定，以最大限度地降低功耗，同时确保治疗效果。
