    摘要: A cardiac rhythm management system modulates the delivery of pacing and/or autonomic neurostimulation pulses based on heart rate variability (HRV). An HRV parameter being a measure of the HRV is produced to indicate a patient's cardiac condition, based on which the delivery of pacing and/or autonomic neurostimulation pulses is started, stopped, adjusted, or optimized. In one embodiment, the HRV parameter is used as a safety check to stop an electrical therapy when it is believed to be potentially harmful to continue the therapy.

    摘要: A method and system for identifying and assessing inter-atrial conduction delays in patients is disclosed. Patients who are so identified and are also in need of ventricular resynchronization therapy may then be treated with left atrial pacing and ventricular resynchronization pacing. Certain patients may alternatively be treated with ventricular resynchronization therapy delivered with a conservatively selected atrio-ventricular delay interval and without left atrial pacing.

    摘要: A device for measuring a synchronicity of contraction of a heart to determine if an individual would be a responder to cardiac resynchronization therapy. The device may include a first electrode positioned at a first ventricular wall location to measure movement of the first ventricular wall location and generate a first signal, as well as a second electrode positioned at a second ventricular wall location to measure movement of the second ventricular wall location and generate a second signal. A processing module may process the first and second signals, for example, integrate the signals multiple times, and generate an output based on the processed signals. Based on this output, an individual can be labeled a responder or non-responder to cardiac resynchronization therapy. The electrodes may each include an accelerometer to measure acceleration of the heart wall.

    摘要: Methods and devices are disclosed for employing mechanical measurements to synchronize contractions of ventricular wall locations. Accelerometers that may be placed within electrode leads are positioned at ventricular wall locations, such as the left ventricle free wall, right ventricle free wall, and the anterior wall/septum wall. The accelerometers produce signals in response to the motion of the ventricular wall locations. A processor may then compare the signals to determine a difference in the synchronization of the ventricular wall location contractions. The difference in synchronization can be determined in various ways such as computing a phase difference and/or amplitude difference between the accelerometer signals. One or more stimulation pulses may be provided per cardiac cycle to resynchronize the contractions as measured by the accelerometers to thereby constantly and automatically optimize the cardiac resynchronization therapy.

    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: Ectopic cardiac activity can be detected, such as in the absence of a diagnosed tachyarrhythmia episode. In response to the detected ectopic activity, electrostimulation can be provided to a para-Hisian region, such as to activate natural cardiac contraction mechanisms or to interrupt re-entrant cardiac activity. Subsequent ectopic cardiac activity can be detected, and subsequent electrostimulation can be provided to the para-Hisian region, such as according to one or more adjustable electrostimulation parameters.
