This review deals with the mechanisms by which digitalis exerts its "opium-like" action on the ventricular rate in patients with atrial fibrillation. To understand the effect of digitalis on ventricular rate and rhythm, it is essential to learn more about the basic electrophysiologic principles responsible for: atrial fibrillation as such, and the scaling function of the atrioventricular (AV) n...

Aklthouh digitalis is known to produce a variety otrial, junctional, (1 ventricular arihythimmias, atrial flutter due to digitalis intoxication has been rarely reported. The present paper reviews the literature and reports what appears to be the sixteenth case. The available inforimmation on the accepted cases(of atrial flutter due to digitalis toxicity has been analyzed for clues as to when di...

Common Cause of Short QT Interval To the Editor: I read with interest the recent report by Gaita et al1 of short-QT syndrome as a familial cause of sudden death. The authors enumerated other factors that shorten QT interval, such as increased heart rate, hyperthermia, hypercalcemia, hyperkalemia, acidosis, and altered autonomic tone.1 I would like to add another important and common, but undera...

Twenty-four hour recording of electrocardiogram was performed in 5 cases, aged from 42 to 75 years, with paroxysmal tachyarrhythmias (paroxysmal supraventricular tachycardia (PSVT) 2 cases and paroxysmal atrial fibrillation (PAf) 3 cases) for the purpose of assessing the effects of digitalis on sinus node function from the chronobiological point of view. All of the pauses following the terminat...

On the Clinical Use of Digitalis with reference to its prescription, maintenance therapy, intoxication and the patient's knowledge. Kurt Boman, M.D., Departments of Internal and Geriatric Medicine Skellefteå Hospital and Institution of Internal Medicine, University of Umeå, S-901 87 Umeå, Sweden. Digitalis is one of the most frequently prescribed drugs, especially to elderly people. The prescri...

Preceding the study of the effect of digitalis upon coagulation of the blood, the reliability of the Lee and White method was determined in 173 normal adults. The effect of digitalis was then studied in cardiac patients before and after coinpenation and with normal controls in eaegroup: digitalis in clinical doses; addition of heparin to the blood; the heparin tolerance curve; the substitution ...

DURING the past decade, the relationship between digitalis drugs and potassium has been extensively investigated. Attention has been given primarily to the effect of potassium upon the digitalized state. It has been shown that administration of potassium abolishes the cardiotoxic manifestations of digitalis.' The converse has also been established, namely, that depletion of body potassium store...
