    摘要: Systems and methods provide for pacing a heart to improve pumping efficiency of the heart, such as by producing a cardiac fusion response for patient's subject to cardiac resynchronization therapy. A pacing parameter, such as an A-V delay, V-V delay, lead/electrode configuration or vector, is adjusted and a cardiac signal vector representative of all or a portion of one or more cardiac activation sequences is monitored during pacing parameter adjustment. A change in a characteristic of the cardiac signal vector is detected in response to an adjusted pacing parameter, the change indicative of a cardiac fusion response. A pacing therapy may be delivered to produce the cardiac fusion response using the adjusted pacing parameter.

    摘要: An improved technique is described for dealing with the detection of fusion beats when capture verification is performed by a cardiac pacing device such as during a capture threshold determination procedure. Schemes for classifying heart beats may misclassify beats as fusion beats due to feature/morphology changes in the test electrogram waveform that may occur even when capture is achieved.

    摘要: Cardioprotective pre-excitation pacing may be applied to stress or de-stress a particular myocardial region delivering of pacing pulses in a manner that causes a dyssynchronous contraction. Such dyssynchronous contractions are responsible for the desired cardioprotective effects of pre-excitation pacing but may also be hazardous. Described herein is a method and system that uses measures of a patient's heart rate or exertion level to control the duty cycles of intermittent pre-excitation pacing.

    摘要: In an example of a method, the method includes testing for phrenic nerve stimulation (PS) threshold. If PS beats are detected at the pacing output level, analyzing the detected PS beats using criteria to determine if the pacing output level can be declared to be the PS threshold. If the pacing output level cannot be declared to be the PS threshold based on the analysis of the PS beat at the pacing output level, performing a PS beat confirmation procedure. The PS beat confirmation procedure may include delivering additional cardiac paces at the pacing output level to generate additional PS beats, and analyzing the detected PS beats using other criteria to determine if the pacing output level can be confirmed as the PS threshold.

    摘要: An apparatus comprises an implantable cardiac signal sensing circuit and a controller circuit. The implantable cardiac signal sensing circuit provides a sensed depolarization signal from a ventricle and a sensed depolarization signal from an atrium. The controller circuit includes a one-to-one detector circuit and a tachyarrhythmia discrimination circuit. The one-to-one detector circuit measures cardiac depolarization intervals of the atrium and the ventricle and determines whether a relationship of atrial depolarizations to ventricular depolarizations is substantially one-to-one. The tachyarrhythmia discrimination circuit increments a counter when detecting a shortening or prolonging of a V-V interval that immediately precedes the same shortening or prolonging of an A-A interval, classifies the episode as VT according to the counter, and provides the classification of the tachyarrhythmia episode to a user or process.
