SYSTEM AND METHOD FOR QRS COMPLEX DETECTION IN COMPRESSIVELY SENSED ELECTROCARDIOGRAM DATA

摘要

Electrocardiogram (ECG) data is compressible athigh compression ratios using suitable compressive sensing techniques.Methods of detecting QRS complexes in an ECG signal maycomprise receiving compressively-sensed measurements of an ECGsignal; constructing an estimate of the ECG signal from the receivedcompressively-sensed measurements, and detecting QRS complexesin the estimate of the ECG signal. QRS complexes may be detectedby computing the first-order difference of the estimate of theECG signal and processing the first-order difference of the estimateof the ECG signal to locate one or more significant natural blocks,each indicating a QRS complex in the ECG signal. QRS complexesmay also be detected by using a conventional QRS detection algorithmon the estimate of the ECG signal. Also disclosed are relatedsystems for detecting QRS complexes and for compressively sensingECG signals.
