Listen to native speakers pronounce “hemisystole” in real conversational contexts with synchronized timestamps and subtitles.
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.
