Diastole is what
WebThe period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle ( Figure 19.3.1 ). The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The period of relaxation that occurs as the chambers fill with blood is called diastole.

A diastolic murmur is a heart murmur heard during diastole, the time the heart relaxes. "Diastole" came without change from the Greek diastole meaning "a drawing apart." The term has been in use … WebA diastolic (die-a-STOL-ic) heart murmur is an abnormal sound that occurs during diastole (die-AS-tuh-lee), when your heart rests between beats. In a blood pressure reading, the diastolic pressure is the lower number. A murmur may sound like a “swish” or “whoosh.”. It occurs because of blood flowing in your heart’s valves.
