摘要： The present invention is a device localization system that uses one or more ultrasound reference catheters to establish a fixed three-dimensional coordinate system within a patient's heart using principles of triangulation. The coordinate system is represented graphically in three-dimensions on a video monitor and aids the clinician in guiding other medical devices, which are provided with ultrasound transducers, through the body to locations at which they are needed to perform clinical procedures. In one embodiment of a system according to the present invention, the system is used in the heart to help the physician guide mapping catheters for measuring electrical activity, and ablation catheters for ablating selected regions of cardiac tissue, to desired locations within the heart.

摘要： Endocardial system and method in which noise and artifacts introduced by a simulator are decoupled from a recorder by connecting the stimulator to the electrodes used for pacing and recording only when it is necessary to do so. At other times, the stimulator is disconnected, and low level signals are recorded without interference from the stimulator. In one embodiment, the stimulator is connected only during the time the pacing pulse is being delivered. In another, a stimulator which delivers pacing pulses in response to intrinsic activation of tissue at the pacing site is connected during delivery of a pacing pulse, disconnected during the measurement period which follows, and then reconnected so that it can sense further intrinsic activity and deliver another pacing pulse.
