Few of the reported cases of congenital complete heart block have been over twenty years of age. It seems, therefore, worth reporting seven cases who are in good health at various ages between 22 and 42 years. This aetiological factor should, therefore, be thought of in middle-aged and even in elderly patients with complete heart block of unknown oetiology. Campbell and Suzman (1934), reporting...

seven hours twenty minutes before delivery, the foetal heart sounds became audible. The very slow rate was noted. It was regular, and the provisional diagnosis of complete heart block was suggested. At delivery the condition of the infant was good: there was no cyanosis. Auscultation of the heart disclosed no murmurs. The ventricular rate fluctuated from timne to timie and varied between sixty ...

Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...
