Effects of propranolol on response to exercise in dial restraining effect contributing to the changes in hypertrophic obstructive cardiomyopathy. Br Heart J left ventricular diastolic pressure-volume relations remains unknown. Improved left ventricular relaxation may be a potential mechanism for the improved diastolic compliance. In a number of studies several indices of left ventricular relaxation were determined, and an improvement in the relaxation properties was reported after treatment with verapamil in patients with hypertrophic cardiomyopathy.7 14-16 Though in 1970; 32;Edwards, R.H.T.; Kristinsson, A.; Warrell, D.A.

5. Kelthe present study changes in left ventricular relaxation were not assessed, it is possible that improved relaxation contributed to the improved diastolic compliance in some of our patients. Kaltenbach et al noted a decrease in left ventricular thickness by contrast ventriculography,5 which may partly explain the increased end diastolic volume after ler M, Petersen Y.
