Hemisystole \Hem`i*sys"to*le\, n. (Physiol.) Contraction of only one ventricle of the heart. [1913 Webster] Note: Hemisystole is noticed in rare cases of insufficiency of the mitral valve, in which both ventricles at times contract simultaneously, as in a normal heart, this condition alternating with contraction of the right ventricle alone; hence, intermittent hemisystole. [1913 Webster]
