    摘要: A filter system for detecting and removing small amplitude, high frequency signals such as muscle artifact signals is provided. One form of the system includes a baseline wander filter, high and low pass filters, an adaptive line noise canceler and various noise detectors to identify, signal and remove muscle artifact or loose electrode signal contamination from an ECG signal wherein the ECG signal is conditioned to remove various portions of the ECG signal, such as the QRS portion of the ECG signal, prior to processing in various noise detectors while minimizing the signal conditioning effect of the filters on the ECG signal and while further providing the operator with the ability to manually or automatically activate the filters and to indicate the status of the filters on a printout or display.

    摘要: A method and apparatus for retaining a catheter tip in a fixed position within a blood flow and preventing it from contacting a blood vessel wall. The apparatus includes a tip retainer at the distal end of the catheter that stabilizes the tip of the catheter relative to the blood vessel. The catheter tip is retained within the blood vessel spaced from the wall to ensure that it does not contact the wall of the blood vessel. This reduces damage to the blood vessel caused by chronic movement and contact between the catheter tip and the wall of the blood vessel. In one embodiment, the tip retainer includes a prong that penetrates the wall of the blood vessel, thus preventing the catheter tip from moving longitudinally within the blood vessel. In alternative embodiments, the tip retainer contacts the wall but does not penetrate the wall.
