[Comparison of corrected orthogonal leads with standard ones using the Minnesota code criteria].
Three corrected orthogonal leads are compared with 12 standard ECG leads. The method of restoration of the leads was used by means of which 12 standard leads are first restored from 3 corrected leads after which a diagnosis is made separately from the natural and the restored leads. To reduce the effect of subjectivism to the minimum, the Minnesota code criteria was used in the diagnosis. The ECG of 153 patients with ischemic heart disease and post-infarction cardiosclerosis and the ECG of 50 practically healthy individuals were anlayzed. The analysis showed that the diagnosis of cicatricial changes consequent upon infarction of the anterior myocardial wall according to restored leads was inferior by 6.6% to the diagnosis made from the 12 natural leads; the diagnosis of infarction of the posterior wall of the left ventricular myocardium as well as of infarction of anteroposterior localization may be made with the same precision as when made from 12 standard leads.
