Patent ID: 8473038

Claim:
A mobile and web-based management information system for processing clinical 12-lead electrocardiogram (ECG), comprising: (a) a clinical device for automatically extracting an XML-ECG file and processing signals; (b) an ECG database for saving web-based data exported from the clinical device, and a mobile device client database which is synchronized with the ECG database; and (c) an interactive electric document for annotating 12-lead ECG with clinical diagnosis codes, wherein the device for automatically extracting the XML-ECG file and processing signals comprises: (a1) a device for reading and decoding content of report information (reportinfo tag), data acquisition information (measurements tag), patients' information (patient tag), interpretation information (interpretations tag) and waveforms information (waveforms tag); and (b1) a means for processing noise, wherein the means for processing noise filters out interference due to baseline drift or high frequency noise via stationary wavelet transform comprising a formula: ECG ⁡ ( t ) = ∑ k ⁢ a k ⁢ ϕ ⁡ ( t - k ) + ∑ k ⁢ ∑ j ⁢ d j , k ⁢ Ψ ⁡ ( 2 j ⁢ t - k ) where ECG(t) means a time sequence of ECG signals; ψ means a generating function; φ means a scaling function; a k means an approximate coefficient of stationary wavelet decomposition at j-level; d j , k means a detail coefficient of stationary wavelet decomposition at j-level, and expressed as: d jk = median ⁡ ( d j , k ) 0.6725 ⁢ 2 ⁢ ⁢ ln ⁢ ⁢ N * f , where f = j + 1 if ⁢ ⁢ j = 1 ⁢ ⁢ or ⁢ ⁢ 2 f = 1 j + 1 if ⁢ ⁢ j > 2 ; j ⁢ ⁢ means ⁢ ⁢ a ⁢ ⁢ decomposition ⁢ ⁢ order ; k ⁢ ⁢ means ⁢ ⁢ a ⁢ ⁢ discrete ⁢ - ⁢ time ⁢ ⁢ transfer ; and f ⁢ ⁢ means ⁢ ⁢ a ⁢ ⁢ revised ⁢ ⁢ parameter ⁢ ⁢ of ⁢ ⁢ threshold .
