METHOD OF EVALUATING EFFECT OF PROLONGING QT INTERVAL IN ELECTROCARDIOGRAM

摘要

A method for evaluating electrocardiogram QT interval-prolonging action of a test substance, which comprises preparing a hamster anesthetized under such a condition that end of T wave is definitely observed on an electrocardiogram, and comparing electrocardiogram QT intervals of the hamster observed before and after administration of the test substance to evaluate electrocardiogram QT interval-prolonging action of the test substance.
