From The Collaborative International Dictionary of English v.0.48 [gcide]:

  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]
