Abstract:
Systolic time intervals were studied in a total of 83 patients with pure or predominant isolated valvular heart disease. They consisted of three groups of patients : namely, 38 cases of mitral stenosis, 25 cases of mitral regurgitation and 20 cases of aortic regurgitation. The mean of the electromechanical systole was within normal ranges in all three groups, and threre was no significant difference between the groups. The mean of the left ventriclar ejection time was also within normal limits in all groups, as was that of the electromechanical systole, but it was significantly shorter in patients with mitral regurgitation than in the others, and was significantly longer in patients with aortic regurgitation. The mean of the pre-ejection period and the ratio of the pre-ejection period to the left ventricular ejection time were within normal ranges in patients with aortic regurgitation, whereas both parameters were significantly increased in patients with mitral stenosis or mitral regurgitation, particularly in the latter.
