The clinical evidence of the two derivation systems is of the same value concerning the recognition of the coronary heart disease. Their information range does not significantly differ from each other statistically, when scale and vectorial parameters of the corrected orthogonal ECG after Frank are taken into consideration. But in individual cases clear differences may be present, such as the insufficient representation of localized precordial potential losses in the corrected orthogonal ECG. With the help of the discriminance analysis the high number of falsely negative findings of the ECG after resting can be reduced from about 45% to 15% to 20%. Within a diagnostic stage programme from the recognition and care of particularly endangered patients with coronary heart disease the corrected orthogonal ECG is suited, when a discriminance-analytic valuation with scale and vectorial parameters is made. In contrast to the conventional ECG it has the advantage that it is more rapidly and less expensively to be evaluated by computers.
