Abstract
A study of the clinical aspects of complete auriculoventricular heart block was based on an analysis of the case records of 71 patients admitted to the Univ. of Iowa hospitals over a 10-yr. period. It was most commonly associated with hypertensive heart disease and coronary solerosis. However, digitalis intoxication accounted for a substantial number of cases. The importance of recognizing the latter as a possible cause is stressed. Only 25 of the total series had symptoms that were attributed directly to complete A-V heart block. Treatment of the conduction defect was considered advisable in approx. 1/3 of the cases. Its importance was evident by the frequency with which it was accompanied by severe symptoms or other significant manifestations of heart disease. Wide pulse pressure which sometimes is found in patients with complete A-V heart block was discussed.
