Diagnostic possibilities of the uncorrected orthogonal ECG Trethewie system in ventricular overload

The possibilities of the uncorrected orthogonal ECG system (Trethewie) in assessment of the ventricular overload have been studied. The uncorrected orthogonal ECG system detects the left ventricular overload better than conventional ECG system. The simultaneous application of both uncorrected orthogonal ECG and conventional ECG increases the diagnostic possibilities of the ECG method.
