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： The current invention provides an improved system for monitoring status of an IMD within a body. The system includes a device such as a lead, guidewire, stylet, catheter, or other IMD carrying a device such as a microphone for detecting acoustic signals in the body. The IMD is coupled to an amplifier device which generates an audible signal that may be utilized to determine status associated with the IMD, including location and tissue-contact data. A processing circuit may further be provided to aid in the analysis of the acoustic data.
