diastole

 [di-as´to-le]
the phase of the cardiac cycle in which the heart relaxes between contractions; specifically, the period when the two ventricles are dilated by the blood flowing into them. See also blood pressure and heart. adj., adj diastol´ic.
electrical diastole that time during which the cell rests; it is represented by phase 4 of the action potential.

di·as·to·le

(dī-as'tō-lē),
Normal postsystolic dilation of the heart cavities, during which they fill with blood; diastole of the atria precedes that of the ventricles; diastole of either chamber alternates rhythmically with systole or contraction of that chamber.
[G. diastolē, dilation]

diastole

/di·as·to·le/ (di-as´tah-le) the dilatation, or the period of dilatation, of the heart, especially of the ventricles.diastol´ic

diastole

(dī-ăs′tə-lē)
n.
1. Physiology The normal rhythmically occurring relaxation and dilatation of the heart chambers, especially the ventricles, during which they fill with blood.
2. The lengthening of a normally short syllable in Greek and Latin verse.

di′as·tol′ic (dī′ə-stŏl′ĭk) adj.

diastole

[dī·as′təlē]
Etymology: Gk, dia + stellein, to set
the period between contractions of the atria or the ventricles during which blood enters the relaxed chambers from the systemic circulation and the lungs. Ventricular diastole begins with the onset of the second heart sound and ends with the first heart sound. Compare systole. See also adiastole.

diastole

The period in the heart cycle when the main pumping chambers (the ventricles) are relaxed and filling with blood from the upper chambers (the atria).

diastole

diastole

the phase between beats when the heart muscle is relaxed, and the chambers are filling. See also cardiac cycle, electrocardiogram, venous return.

period within the cardiac cycle when atria and ventricles relax, dilate and fill with blood (see systole)

diastole (dīas´təlē),

n 1. the rhythmic period of relaxation and dilation of a chamber of the heart during which it fills with blood.
n 2. the period after the contraction of the heart muscle, during which the aorta releases the potential energy stored in its elastic tissue. The energy is converted into kinetic energy and sustains the pressure necessary for steady flow of blood in the vessels. The pressure measured at this period is the lowest attained during the cardiac pumping cycle and is called the
diastolic pressure. The normal pressure in the adult is approximately 120/80 mm Hg (systolic/diastolic) and increases with age from 128/85 at 45 years of age to 135/89 at 60 years of age. See also blood pressure classification.

diastole
