THE EFFECT OF PHENOTHIAZINES ON THE ELECTROCARDIOGRAM.

Thioridazine, chlorpromazine and trifluoperazine were administered to six psychiatric patients. Each was used in four dosage levels (thioridazine and chlorpromazine: 200, 400, 800 and 1200 mg. daily; trifluoperazine: 8, 16, 32, 64 mg. daily); and each increase in dosage was effected after four days of drug administration.Before the trial, twice during each drug period and before commencement of the next dose regimen, an electrocardiogram (ECG) was recorded. The findings indicated that thioridazine modifies the terminal portion (S-T segment, T and U waves) of the human ECG. A similar change occurred in three of six subjects while taking chlorpromazine and in one of six while taking trifluoperazine. Thioridazine induced changes in all six subjects studied, viz., blunting and notching of T waves with or without prolongation of QT interval. In some the notching produced a doublehump appearance in which a T wave of reduced voltage formed the proximal hump and a positive U wave of increased voltage formed the distal hump.Thioridazine-induced alterations in the ECG have been described as resembling those caused by quinidine; they also resemble changes associated with hypokalemia.

Comparative clinical study of two hypnotic drugs.

The comparative sleep-inducing and sleep-sustaining effects of glutethimide, 0.5 g., and ethchlorvynol, 0.5 g., were studied in 20 patients hospitalized for a considerable time (average: 21 years; minimum nine years and maximum 32 years) and not receiving psychotropic agents. Assessment of sleep and para-sleep parameters (pre-sleep tension; frequency of awakening at night; post-sleep activity) revealed that patients fell asleep faster (P>.001) and slept for a longer time with ethchlorvynol than with glutethimide.
