[Distribution of lactate dehydrogenase isoenzymes in human myocardium obtained from endomyocardial biopsies].

The distribution of lactate dehydrogenase and its isoenzymes in myocardial tissue obtained by biopsies from within the right ventricle can be studied by electrophoresis in a similar manner to that for making serum determinations. Results are comparable to radioimmunologic dosing (Peters) and microelectrophoresis (Schultheiss) and complete the findings obtained from the histological study of biopsied fragments.
