The relationship between interventricular septum thickness and its function. An echocardiographic study.

By means of a single beam echocardiography the authors investigated the relationship between interventricular septum diastolic thickness and its function, evaulated as percentage of systolic thickening. 55 persons were examined, partly healthy subjects and partly those with various cardiac diseases, excluding the cases with reversed septum motion or local septum dyskinesis. The found correlation between septum thickness and its function was exponential and statistically significant (p less than 0.001; r = --0.805). Thus, the hypothesis concerning the quantitatively dependent deterioration of the septum function on the degree of its hypertrophy was confirmed.
