[Pharmacological electrocardiographic tests in the differentiation of functional and organic changes in the myocardium in malignant neoplasms].

Individually-tailored application of standard pharmacological ECG tests using atropine, inderal and other drugs is still justified. They are more available than some newly-developed methods which are diagnostically superior.
