Monitoring and diagnostic instruments often utilize electrocardiographic R‐wave detection for measuring hearl rate or for timing of measurement processes. During cardiac pacing stimulus artifacts commonly interfere with the operation of such instruments because they are misinterpreted as R‐waves. This phenomenon creates problems in assessing the hernodynamics during gated blood‐pool scans, coronary care monitoring, and intra‐aorlic balloon pumping. A straightforward solution is found in the nature of the electrical signals involved in which the stimulus artifacts are detected independently and are removed from the signal fed to the R‐wave detector.
