Modern QRS detectors in patient monitoring systems must provide accurate results even when interfering noise is present. This task is complicated by the heterogeneous and non-uniform nature of the patient population. Certain beat morphologies demand a significant increase in the complexity of beat detection algorithms. At the same time, it is important to take a system-wide approach to the beat detection...
An algorithm for analyzing changes in ECG morphology based on principal component analysis (PCA) is presented and applied to the derivation of surrogate respiratory signals from single-lead ECGs. The respiratory-induced variability of ECG features, P waves, QRS complexes, and T waves are described by the PCA. We assessed which ECG features and which principal components yielded the best surrogate...
Even though an analogue high-pass single pole filter with 0.05 Hz cut-off has been used for decades to define the low frequency response of electrocardiographs, in recent years the requirements for diagnostic quality ECG recordings have been expressed in terms of the system magnitude characteristic and its response to a rectangular pulse. The objective of this work is to design an analogue high-pass...
A textile-based ECG system for sleeper is presented. The electrode in the system is supported by a foam pad to ensure good contact as well as comfort to the wearer, and a flexible rubber to ensure that the electrode will electrically connect to the wearer only when pressed. Eight electrodes are multiplexed such that exactly two electrodes are pressed to connect the wearer no matter how the wearer...
