1.
Use of techniques from communication analysis in diagnosis of myocardial infarction from body surface potential maps.
Fischmann, E J; Weinstein, S B.
Adv Cardiol ; 21: 90-5, 1978.
Article in English | MEDLINE | ID: mdl-619577

ABSTRACT

A correlation test was applied to superimposed plots of partial body surface potential maps in order to distinguish between normal subjects and those with independently diagnosed myocardial infarction. The reference waveform is determined by means of a gradient-search algorithm.
