    摘要: The implantable medical device (IMD) system disclosed here utilizes one or more cardiac sensors that measure mechanical characteristics of the heart, such as left ventricular acceleration or right ventricular pressure. The raw sensor data is collected and processed by the IMD, which derives one or more mechanical event marker signals from features, traits, and characteristics of the sensor data waveforms. The mechanical event marker signals are wirelessly transmitted to an external monitor device for display.

    摘要: A medical device system and method for delivering mechanically fused left ventricular cardiac stimulation. A sensor monitors left ventricular acceleration while left ventricular cardiac stimulation is provided at an AV interval. The left ventricular acceleration is used to calculate a mechanical response interval and the mechanical response interval is compared to a desired mechanical response interval. The AV interval is adjusted until the mechanical response interval is equal to the desired mechanical response interval.

    摘要: A method for determining an optimal pacing timing control parameter setting is provided for use in an implantable medical device programmed to deliver a pacing pulse in response to the timing control parameter. The method includes storing a user-selected optimization metric, iteratively adjusting the timing control parameter setting, sensing a first signal that varies in response to left ventricular wall acceleration, measuring the user-selected optimization metric in response to the sensed first signal, and determining an optimal timing control parameter value in response to the measured user-selected optimization metric.
