Supports electrolyte vigilance with digitalis; leaves open relevance to contemporary low-dose HF regimens.
This monograph is concerned with the analysis of 64 cases of paroxysmal atrial tachycardia with atrioventricular block caused by digitalis intoxication. The authors point out that this manifestation of digitalis toxicity has been increasing in incidence in the past few years as patients with congestive heart failure are treated vigorously with such drugs as mercurial diuretics which may cause cellular potassium depletion. Treatment for this condition is to stop digitalis and diuretic administration temporarily and give the patient potassium. The use of a chelating agent, such as sodium ethylenediaminetetraacetate, to induce hypocalcemia is also advocated in certain cases. The relationship of the potassium and calcium ions to digitalis dosage and toxicity is discussed at some length, as well as the clinical and electrocardiographic differentiation from other arrhythmias. The book is well illustrated, and the text is well written and easy to read. It is recommended for internists and cardiologists.

A 1958 study conducted a review in Paroxysmal atrial tachycardia with atrioventricular block caused by digitalis intoxication (n=64). Digitalis intoxication and potassium depletion was evaluated. Analysis of 64 cases of paroxysmal atrial tachycardia with AV block caused by digitalis intoxication highlights the role of potassium depletion and advocates for stopping digitalis and administering potassium.
