Why the study?
Is the prolongation of left ventricular ejection time in the post-premature beat a more sensitive sign of idiopathic hypertrophic subaortic stenosis than the change in pulse pressure?

May support LVET prolongation as adjunctive IHSS marker; challenges Brockenbrough primacy but leaves open prospective validation.
Is the prolongation of left ventricular ejection time in the post-premature beat a more sensitive sign of idiopathic hypertrophic subaortic stenosis than the change in pulse pressure?
Prolongation of the left ventricular ejection time during the post-premature beat is a more sensitive hemodynamic sign of idiopathic hypertrophic subaortic stenosis than the traditional Brockenbrough sign.
White et al. (1975) studied this question.
