1570s, from medical Latin diastole, from Greek diastole "drawing asunder, dilation," from diastellein, from dia- "through, thoroughly, entirely" (see dia-) + stellein "to set in order, arrange, array, equip, make ready," from PIE *stel-yo-, suffixed form of root *stel- "to put, stand," with derivatives referring to a standing object or place (see stall (n.1)).
1. Each heartbeat has two basic parts: diastole and atrial and ventricular systole.
2. The length in the diastole was bigger than that in the systole.
3. Intensity of radio signal also had this variation between in diastole and in systole.
4. Regurgitant murmurs are generally early diastolic whereas ventricular filling murmurs occur in mid and late diastole.
5. Diastolic murmurs are classified according to their position in diastole as early, mid, or late.
