title: [Electrophysiological classification of myocardial infarct].
abstract: The paper treats some questions concerning the electrophysiological diagnosis of myocardial infarction. An attempt has been made to work out an electrophysiological classification of myocardial infarction basing on 4 categories: localization, stage, volume, electrical instability. In new concept reversibility of changes at the very early stage of the disease has been developed. Great importance was given to the volume of the lesion, and to electrical instability. Three types of electrical instability were differentiated (the myocardium, automatic centers, atrioventricular system) and the "staircase phenomenon" has been described. All the categories were classified and coded and as a result a formula was proposed to express and asses in terms of codes and mathematical figures all the features of the process. The importance of this formula for the application of computers in electrocardiology was stressed.
