Cardiovascular Dynamics in Complete Heart Block at Various Heart Rates
Thirteen patients with complete atrioventricular block resulting from coronary disease were studied. In seven the diagnosis of coronary disease was established by the presence of typical history and electrocardiographic and enzymatic findings compatible with an acute infarction. Of the remaining six cases, three had a typical history of angina pectoris. In three cases there was no history of my...

متن کاملHyperkalemia-induced complete heart block
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...

متن کاملCongenital Complete Heart Block.
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...
