An apparatus detects corruption of an event signal by two or more non-event artifacts by using multivariable artifact assessment. The apparatus comprises: 1) a sensor for providing an input signal comprising an event signal coexisting with two or more non-event signals, 2) a measurement system including a receiver for receiving the input signal from the sensor and separating the received input signal into its constituent parts, 3) detectors for detecting both the event signal and non-event signals from the received input signal, and 4) an inference processor for analyzing the correlation signals to produce an indication of signal corruption. In a second embodiment, the apparatus comprises: 1) a plurality of sensors for providing additional non-event input signals, 2) a corresponding measurement system having a plurality of receivers for receiving the additional input signals, 3) detectors for detecting the non-event signals from the received additional input signals, 4) correlators for comparing the detected event signal with each of the detected non-event signals to produce respective correlation signals, and 5) an inference processor for analyzing the correlation signals to produce an indication of signal corruption. The apparatus may be a patient monitoring system or a defibrillator. Methods of operating the apparatus are also described.

[ What is claimed:] [1.]1. An apparatus for detecting corruption of an event signal with artifact in an environment where the potentially corrupted event signal coexists with two or more non-event signals which may be related to the artifact, the apparatus comprising:a sensor for providing an input signal, wherein the input signal comprises an event signal coexisting with two or more non-event signals;a measurement system for receiving the input signal from the sensor and separating the received input signal into its constituent parts, wherein the measurement system comprises a receiver for receiving the input signal, a detector for detecting the event signal from the received input signal, and detectors for detecting the non-event signals from the received input signal;correlators for comparing the detected event signal with each of the detected non-event signals to produce respective correlation signals; andan inference processor for analyzing the correlation signals to produce an indication of signal corruption.
