    摘要： An isolated heart preparation in which essentially normal pumping activity of all four chambers of the heart is preserved, allowing for the use of the preparation in conjunction with investigations of electrode leads, catheters, cardiac implants and other medical devices intended to be used in or on a beating heart. The preparation may also be employed to investigate heart functions, in the presence or absence of such medical devices. In order to allow for visualization of heart structures and devices located within the chambers of the heart, a clear perfusate such as a modified Krebs buffer solution with oxygenation is circulated through all four chambers of the heart and the coronary vasculature. The preparation and recordings of the preparation may be used in conjunction with the design, development and evaluation of devices for use in or on the heart, as well as for use as an investigational and teaching aid to assist physicians and students in understanding the operation of the heart.

    摘要： A method for delivering physiological pacing includes selecting an electrode implant site for sensing cardiac signals, which is in proximity to the heart's intrinsic conduction system, where pacing stimulation results in a rhythm breaking out at an intrinsic location, and selected in response to a ratio of sensed P-wave amplitude to sensed R-wave amplitude.

    摘要： A method for delivering physiological pacing includes selecting an electrode implant site within an interventricular septal zone, which is in proximity to the bundle of His where pacing stimulation results in a rhythm breaking out at an intrinsic location, and wherein a ratio of sensed P-wave amplitude to sensed R-wave amplitude is less than approximately 0.5 and a pacing threshold is less than or equal to approximately 1.5 volts.

    摘要： An improved system for monitoring the status of an IMD such as a medical electrical lead during an implant procedure is provided. The system includes a signal generator for supplying a first signal such as a constant current or voltage to the IMD. A resulting voltage or current signal is generated, respectively, and may be sensed as an indication of the impedance of a portion of the body that is proximal to one or more electrodes carried by the lead. This impedance indication is converted to an audible signal having a frequency that is proportional to the amplitude of the impedance indication. The pitch of the audible signal therefore rises when measured impedance increases, and drops as the impedance decreases. These pitch changes allow a user to determine positional information associated with the IMD, including the degree of lead tissue contact and extent of fixation of a device to tissue.
