ABSTRACT:
A system for identifying artifact in automatic blood pressure measuring system. The system determines whether a single blood pressure signal, such as an oscillometric pulse or Korotkoff sound, occurs for each QRS complex of an ECG waveform in order to verify that the blood pressure signal is valid. In the event that multiple blood pressure signals occur between successive QRS complexes, at least some of the blood pressure signals are determined to be induced by artifact.
