Electrocardiographic effects of nortriptyline, phenelzine, and placebo under optimal treatment conditions. 1987

A Georgotas, and R E McCue, and E Friedman, and T B Cooper

The authors treated 44 outpatients 55 years old or older who were suffering from major depression with either nortriptyline, phenelzine, or placebo for 7 weeks. Plasma levels of nortriptyline were kept between 50 and 170 ng/ml, and platelet monoamine oxidase (MAO) inhibition in phenelzine-treated patients was kept between 70% and 80%. ECGs were compared before and after treatment. Nortriptyline produced statistically significant increases in both the heart rate and the PR interval, although none was outside the normal range. Phenelzine produced a significant decrease in the QT interval. None of the patients had pathological ECG changes under the closely monitored treatment conditions of this study.

D010919 Placebos Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.

D004562 Electrocardiography Recording of the moment-to-moment electromotive forces of the HEART as projected onto various sites on the body's surface, delineated as a scalar function of time. The recording is monitored by a tracing on slow moving chart paper or by observing it on a cardioscope, which is a CATHODE RAY TUBE DISPLAY. 12-Lead ECG,12-Lead EKG,12-Lead Electrocardiography,Cardiography,ECG,EKG,Electrocardiogram,Electrocardiograph,12 Lead ECG,12 Lead EKG,12 Lead Electrocardiography,12-Lead ECGs,12-Lead EKGs,12-Lead Electrocardiographies,Cardiographies,ECG, 12-Lead,EKG, 12-Lead,Electrocardiograms,Electrocardiographies, 12-Lead,Electrocardiographs,Electrocardiography, 12-Lead
