摘要： Tools and methods are particularly suited for certain cardiac conditions involving use of a catheter for pacing of the right and left ventricles from a lead in the right ventricle, e.g., to facilitate mechanically and/or electrically synchronous contractions for resynchronization. Certain aspects involve pacing and/or mapping by generating pulses for delivery to a cardiac site useful for improving heart function as measured, e.g., by QRS width, fractionation, late LV activation timing, mechanical synchronicity of free wall and septal wall, effective throughput/pressure, or a combination thereof. In one embodiment, an implantable pulse generator includes circuitry for generating pacing profiles, with signals of opposite polarities, specifically selected for delivery on electrodes at a site near the septal wall of a right ventricle of the heart.

摘要： A cardiac rhythm management system provides for ambulatory monitoring of hemodynamic performance based on quantitative measurements of heart sound related parameters for diagnostic and therapeutic purposes. Monitoring of such heart sound related parameters allows the cardiac rhythm management system to determine a need for delivering a therapy and/or therapy parameter adjustments based on conditions of a heart. This monitoring also allows a physician to observe or assess the hemodynamic performance for diagnosing and making therapeutic decisions. Because the conditions of the heart may fluctuate and may deteriorate significantly between physician visits, the ambulatory monitoring, performed on a continuous or periodic basis, ensures a prompt response by the cardiac rhythm management system that may save a life, prevent hospitalization, or prevent further deterioration of the heart.

摘要： Tools and methods are particularly suited for certain cardiac conditions involving use of a catheter for pacing of the right and left ventricles from a lead in the right ventricle, e.g., to facilitate mechanically and/or electrically synchronous contractions for resynchronization. Certain aspects involve pacing and/or mapping by delivering pulses to a cardiac site useful for improving heart function as measured, e.g., by QRS width, fractionation, late LV activation timing, mechanical synchronicity of free wall and septal wall, effective throughput/pressure, or a combination thereof. In one embodiment, a catheter arrangement includes a fixation mechanism to attach the catheter arrangement to heart tissue, individually-addressable electrodes for providing pacing signals to the heart tissue, and an elongated structure that supports the fixation mechanism and the electrodes. The elongated structure is used to direct an end thereof to the target region in the right ventricle, and deliver an electrical pacing signal to different portions within the target region of the heart when the fixation mechanism is operative to attach to heart tissue and also when the fixation mechanism is not attaching the catheter arrangement to heart tissue.

摘要： Various systems, methods and arrangements are implemented in connection with ventricular pacing. One such method relates to a method for use in connection with ventricular pacing of a left ventricle of a heart from a pacing lead located in the right ventricle. Ventricular function of the heart is sensed. The sensed ventricular function is used to determine whether a conduction abnormality exists. The ventricular pacing is provided in response to determining a conduction abnormality exists and the ventricular pacing is inhibited in response to determining a conduction abnormality does not exist.

摘要： Various systems, methods, devices and arrangements are implemented for use in pacing of the heart. One implementation is directed to methods and systems for determining a pacing location in the right ventricle of a heart and near the His bundle. A pacing signal is delivered to the location in the right ventricle. The pacing signal produces a capture of a left ventricle. Properties of the capture are monitored. Results of the monitored capture are used to assess the effectiveness of the delivered pacing signal as a function of heart function. The heart function can be, for example, at least one of a QRS width, fractionation and a timing of electrical stimulation of a late activation site of a left ventricle relative to the QRS.
