Webster's Revised Unabridged Dictionary
    • Systole (Physiol. & Biol) The contraction of the heart and arteries by which the blood is forced onward and the circulation kept up; also, the contraction of a rhythmically pulsating contractile vacuole; -- correlative to diastole.
    • Systole (Gram) The shortening of the long syllable.

Century Dictionary and Cyclopedia
    • n systole In anc. orthoëpy and prosody: Pronunciation of a vowel as short.
    • n systole The shortening of a vowel or syllable, especially of one usually treated as a long; correption: opposed to diastole or ectasis.
    • n systole In physiology, the contraction of the heart and arteries for propelling the blood and thus carrying on the circulation. Clinically, systole usually refers to the ventricular systole, regarded as beginning with the first sound and ending with the occurrence of the second sound. Compare diastole.
    • n systole The contraction of the pulsatile vesicles of infusorians and other protozoans.
