ABSTRACT
An electrocardiogram tracing of a patient in conducted sinus rhythm with left bundle branch block is shown, in which occasional pseudonormalization of intraventricular conduction is seen. This event is attributed to ventricular fusions with end-diastolic extrasystoles of the left His-Purkinje system distal to the block site. This type of extrasystole is discussed. In this case, normalization of ventricular activation allowed for diagnosis of inferior subepicardial ischemia.

One aspect of family adaptation to a young child with disabilities was investigated through comparison of expressed needs of mothers and fathers and examination of the relation of those needs with selected child and family characteristics. A diverse sample of more than 400 parents completed the Family Needs Survey (Bailey & Simeonsson, 1988). A factor analysis of the items for mothers yielded six distinct factors. A confirmatory factor analysis of needs expressed by fathers indicated a structure that differed significantly from that found for mothers. Mothers expressed significantly more needs than did fathers. Although SES and disability type accounted for significant variance in needs of mothers, an examination of mean values suggested the effect to be of limited clinical significance.
