Complete heart block with normal QRS duration occurring distal to the his bundle in acute inferior myocardial infarction.

A patient with acute inferior myocardial infarction developed on the second day complete heart block with normal QRS duration, and the block was found to be distal to the His bundle. To our knowledge, this is the first such documented case in the English literature. Failure of the preceding Wenckebach periods and of complete heart block to respond to intravenous atropine may be a clinical clue to the nature of this type of heart block. The implications and possible explanations are discussed in the light of recent knowledge concerning the nature of heart block in inferior wall myocardial infarction.

Evidence for specialized atrioventricular conduction in hyperkalemia.

A patient who had chronic coarse atrial fibrillation developed severe hyperkalemia accompanied by total loss of fibrillatory waves while an irregularly irregular ventricular rhythm persisted. Correction of hyperkalemia resulted in prompt return of coarse atrial fibrillation. This sequence of events renders strong support to direct atrioventricular conduction through the specialized internodal tracts.

His bundle electrogram in congenitally corrected transposition of the great vessels.

His bundle electrogram was recorded in a young adult male with corrected transposition of the great vessels and single ventricle. Prolonged PA and AH intervals, wide diphasic His spike, and normal HV intervals were found. These findings are suggestive of the diffuse nature of conduction delay in this congenital lesion involving intra-atrial, AV nodal, and intra-His regions.

Electrocardiographic abnormalities in alcoholic cardiomyopathy. A study of 65 patients.

Electrocardiograms of 65 patients with alcoholic cardiomyopathy seen over a five-year period were reviewed. ST segment and T wave abnormalities, left ventricular hypertrophy, biatrial enlargement, left atrial enlargement, premature ventricular contractions, prolonged PR interval, and left anterior hemiblock are the most frequently encountered abnormalities. A combination of left ventricular hypertrophy and biatrial enlargement with or without left anterior hemiblock is most specific, Atrial flutter or fibrillation, pathologic Q waves, and bifascicular block are not uncommon findings, while isolated right atrial or right ventricular abnormalities, and isolated posterior hemiblock or right bundle branch block are rare. Electrocardiographic changes are in general similar to those seen in any diffuse cardiomyopathy and reflect biventricular involvement.
