B. Goswami et al., THE POLAR PHASE RESPONSE PROPERTY OF MONOPOLAR ECG VOLTAGES USING A COMPUTER-AIDED-DESIGN AND DRAFTING(CAD)-BASED DATA-ACQUISITION SYSTEM, International journal of bio-medical computing, 33(3-4), 1993, pp. 209-217
The present paper discusses a Computer-Aided Design and Drafting (CAD)
based data acquisition and polar phase response study of the ECG. The
scalar ECG does not show vector properties although such properties a
re embedded in it. In the present paper the polar phase response prope
rty of monopolar chest lead (V1 to V6) ECG voltages has been studied.
A software tool has been used to evaluate the relative phase response
of ECG voltages. The data acquisition of monopolar ECG records of ches
t leads V1 to V6 from the chart recorder has been done with the help o
f the AutoCAD application package. The spin harmonic constituents of E
CG voltages are evaluated at each harmonic plane and the polar phase r
esponses are studied at each plane. Some interesting results have been
observed in some typical cases which are discussed in the paper.
