A method and system for near real-time analysis and display of electrocardiographic signals

摘要

The multidimensional ECG processing and display system (60) of the present invention may be used with an electrocadiographic (ECG) monitoring system. Input ECG data (61) from multiple, sequential time intervals is collected and formatted into a two-dimensional matrix using the processing function (62). The two-dimensional matrix is decomposed using singular value decomposition (SVD) to obtain its corresponding singular values and singular vectors, a compressed form of the matrix. The singular vectors are analyzed and filtered to identify and enhance signal components of interest using the subspace processing function (63) and the signal processing function (64). Selected singular vectors are transformed into their frequency domain representations by the Fast Fourier Transform (FFT), or related techniques.
