[Diagnosis of disorders of the electrolyte metabolism by means of Frank's corrected orthogonal (k.o.) ECG].
The usual ECG criteria in the metabolism disturbance of calcium and potassium are touched. The content of electrolyts in the cells is not to be found in vivo by chemical methods. A loss of potassium in the cell makes a potential difference, which is defined as lesion potenial between the lesion focus and its intact environment. Lesion potentials change the ECG in such a typical manner, that it is possible to locate the latered focus by the ECG pattern in lead x, y and z.
