“…We shall describe the results of using this method on a publicly available database [5] to detect artifacts in arterial blood pressure (ABP) signals by exploiting correlations with ECG signals. Numerous systems have been developed for automatically analyzing patient monitoring signals, and these have employed various methods ranging from traditional signal processing techniques such as frequency analysis, timefrequency analysis, and wavelet analysis [3], [7], [8], [9], [11] to techniques developed by Artificial Intelligence (AI) researchers such as neural networks (NN) [4], [6], [12], [15] and fuzzy logic [1], [10], [16]. The majority of these systems have focused on ECG signals and most of the systems have used a single-signal model, or when they do look at multi-channels, they are of the same type of signal -ECG signals from multiple leads.…”
