hemisystole
半減收縮; 半收縮
Hem·i·sys·to·le n. Physiol. Contraction of only one ventricle of the heart.
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.
