Topic: Diastole


  
  Diastole definition - Medical Dictionary definitions of popular medical terms easily defined on MedTerms
The final letter in "diastole" is pronounced as a long "e" as in "lee." The adjective for diastole is diastolic.
The diastolic pressure is specifically the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart.
A diastolic murmur is a heart murmur heard during diastole, the time the heart relaxes.

  Diastole   (Site not responding. Last check: )
Diastole is the period of time when the heart relaxes after contraction.
Ventricular diastole is when the ventricles are relaxing, while atrial diastole is when the atria are relaxing.
During ventricular diastole, the pressure in the (left and right) ventricles drops from the peak that it reaches in systole.

 Normal Circulation and Congestive Heart Failure
Diastole is the period of left ventricular relaxation and filling, beginning with the closure of the aortic valve and ending with closure of the mitral valve.
During diastole: the major variable which is changing is the radius of the ventricle as it fills with blood, since the radius changes in proportion to the cube root of the volume, while the pressure changes little (see the cardiac cycle diagram) and the thickness changes little.
Even in the absence of systolic dysfunction, diastolic dysfunction may result in all the signs and symptoms of backward failure, due to elevation of the LVEDP resulting in transudation of fluid into the interstitium of the lungs.

 Cardiology Concepts
Diastolic disease of the ventricle is commonly one of the earliest signs of heart disease.
Diastolic disease of the left ventricle is demonstrated by the presence of left atrial enlargement and later pulmonary edema.
The presence of increased velocity of blood flow across the atrio-ventricular valve that normally occurs in late diastole and is associated with atrial contraction suggests the presence of reduced ventricular compliance (the Doppler E wave wave).

 Cardiac cycle Summary
Diastole is the period between ventricular contractions when the right and left ventricles relax and fill.
During ventricular diastole, the pressure in the (left and right) ventricles drops from the peak that it reaches in systole.
In short terms, the diastole phase is where the atria and ventricles are relaxed and not working, while the heart fills itself with blood, and in the systole phase, the ventricles are contracting sending all the oxygenated blood to major and minor arteries.

Today, a much expanded Diastole is available for a wide variety of UMKC functions including retreats, recitals, lectures, continuing education, committee and staff meetings, journal clubs, reunions, study groups, luncheons, dinners and University social gatherings.
Diastole, pronounced (dy-AS-tuh-lee), is a medical term for the interim between heartbeats, when the heart muscle relaxes.
This period, the heart at rest, is Diastole.

 Normal Circulation and Congestive Heart Failure
During diastole, the mitral valve (MV) is open, so that the left atrial (LA) and left ventricular (LV) pressures are equal.
In late diastole, LA contraction causes a small rise in pressure in both the LA and LV (the a wave).
It should be noted that virtually all patients with systolic dysfunction also have some degree of diastolic dysfunction as well, resulting from the decreased compliance of the dilated, fibrotic or hypertrophied ventricle.

 Abandoning diastole British Medical Journal - Find Articles
The key issue in hypertension management in primary care is the treatment of those patients who will benefit from treatment and to ensure that treatment failures are addressed by modifying drug treatment to achieve control of blood pressure.
When systolic pressure is raised, the level of diastolic pressure is usually irrelevant for the purpose of therapeutic decision making.
The exception is in the case of severe hypertension where high systolic combined with high diastolic pressure--for example, [is greater than] 125 mm Hg--may indicate malignant hypertension, which constitutes a medical emergency.

Ventricular diastole is when the ventricles are relaxing, while atrial diastole is when the atria are relaxing.During ventricular diastole, the pressure in the (left and right) ventricles drops from the peak that it reaches in systole.
Diastole (uitspraak diAAstolé) is de medische naam voor de fase waarin het hart zich ontspant en weer volzuigt met bloed.Hoewel de meeste aandacht in de cardiologie en in de geneeskunde traditioneel naar de samentrekkingsfase (systole) uitgegaan is, kunnen er ook bij de diastole stoornissen optreden die een pathologische betekenis hebben.

 Cardiac Cycles   (Site not responding. Last check: )
During diastole, the atria relax as oxygenated blood from the lungs fills the left atrium and deoxygenated (venous) blood from other parts of the body fills the right atrium.
At the end of the diastole, the atria contract, forcing blood into the corresponding ventricles.
During systole the ventricles contract, forcing the blood into the pulmonary artery to be reoxygenated in the lungs, and into the aorta for systemic distribution of oxygenated blood.

The most common approach is to measure the Resistance Index in which the peak of of systole is divided by the sum of systole and diastole.
Therefore, as the duration of pregnancy increases, the amount of blood flowing in the umbilical artery increases during diastole.
To determine the resistance index the peak of systole (Sys Meas) is divided by the sum of the systolic (Sys Meas) and diastolic measurements (Dias Meas).

While blood is pushed from the right ventricle into the lungs to pick up oxygen, oxygen-rich blood flows from the left ventricle to the heart and other parts of the body.
If the diastole part of the two-part pumping phase is abnormal, this is called diastolic dysfunction.
