Method And Apparatus For Frank Lead Reconstruction From Derived Chest Leads

US Patent:
6804550, Oct 12, 2004
Filed:
Sep 27, 2000
Appl. No.:
09/671532
Inventors:
William J. Murray - Wakefield MA
Assignee:
Draeger Medical Systems, Inc. - Danvers MA
International Classification:
A61B 504
US Classification:
600509, 600512
Abstract:
In an ECG monitoring and analyzing system of the type where electrodes are placed on a subject for detecting electrical activity of a heart, and where the electrode placement is such that Frank Leads X, Y and Z can be constructed from the detected electrical activity, an ECG signal transformation network for providing Frank X, Y and Z leads, comprises an input, responsive to a set of input signals corresponding to no more than derived chest leads dV , dV , dV , dV , dV and dV , a memory for storing coefficients of a transformation matrix, and an output, for providing transformation matrix output signals corresponding to application of said transformation matrix coefficients to said input signals, said output signals corresponding to said Frank X, Y and Z leads. The invention reduces bandwidth requirements in an ECG signal communication network, as well as the complexity of the processing required for constructing the Frank Leads.
