Topic: Diastole



  
 Cardiac cycle - Wikipedia, the free encyclopedia
Ventricular diastole is when the ventricles are relaxing, while atrial diastole is when the atria are relaxing.
The term diastole is synonymous with relaxation of a muscle.
Cardiac Diastole is the period of time when the heart relaxes after contraction in preparation for refilling with circulating blood.

 Diastole definition - Medical Dictionary definitions of popular medical terms
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: The time period when the heart is in a state of relaxation and dilatation (expansion).

 PEDIATRIC CARDIOLOGY
During early diastole in patients with an isolated defect, flow was initially from the right to the left ventricle and subsequently reversed to become left to right in 29 (91%) of 32 studies.
We concluded that flow continued from right to left during early diastole and that the flow reversal seen in these patients was the same left to right flow demonstrated by the previous investigators (2).
Diastole was subdivided into an early and a late phase.

Lusitropy, the ability of the cardiac myocytes to relax, is affected by both biochemical events within the myocyte and biomechanical events in the left ventricle.
(5) In this article, we review the electrophysiology of ventricular action potentials; explain the physiological basis of myocardial contraction and relaxation, with an emphasis on diastole; and describe pressure-volume loops, a useful tool for evaluating ventricular function.

 Update in Anaesthesia Issue 18
As about 80% of the total coronary arterial flow occurs during diastole, a pressure around the aortic diastole pressure becomes the primary determinant of the pressure gradient for coronary flow.
Coronary blood flow occurs predominatly during diastole when cardiac muscle relaxes and no longer obstructs blood flow through ventricular vessels.
Conversely, right coronary arterial flow rate is highest during systole, because th aortic pressure driving flow increases more during systole (from 80 to 120mmHg) that the right ventricular pressure which opposes flow (from 0 to 25mmHg).

 Normal Circulation and Congestive Heart Failure
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.
In clinical terms, it is the stretch on the ventricular fibers just prior to contraction, often approximated by the end-diastolic volume or end-diastolic pressure.
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 or hypertrophied ventricle.

 APStracts 3:0422H, 1996.
At a constant perfusion pressure of 62.5 mmHg, the transition from (static) diastole to (static) systole at constant muscle length ("isometric contraction") was calculated to reduce flow by 74% (from 18.9 to 5.0 ml/min/g) and by 64% (from 12.6 to 4.6 ml/min/g), for the muscle fixed at slack length and 90% of Lmax, respectively.
Modeling pressure-flow relations in cardiac muscle in diastole and systole.
Increasing muscle length from slack length to 90% of Lmax decreases coronary flow by 34% in diastole and by 8% in systole.

 Math representation of systole & diastole
The 2 phases in diastole were relaxation and passive filling.
In systole, the phases are slightly more difficult to visualize than they were in diastole, since the increase in contraction intensity continues beyond the point where blood ejection starts (the point in the figure, above, in which ventricle pressure exceeds aortic pressure).
Modeling systole is similar to diastole, in that there are two distinct phases in each.

 British Medical Journal: Abandoning diastole
When systolic pressure is raised, the level of diastolic pressure is usually irrelevant for the purpose of therapeutic decision making.
This confusion among doctors and uncertainties about treatment strategies must be a major explanation underlying the appalling levels of blood pressure control in the United Kingdom and other European countries.
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.

 Cardiac Cycles
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.
One heartbeat—a cardiac cycle—consists of two parts called systole and diastole.
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.

 Diastole - The Scholars Center
Diastole, pronounced (dy-AS-tuh-lee), is a medical term referring to the interim between heartbeats, when the heart muscle relaxes.
There is systole, when the heart beats and delivers life's blood downstream.
Today Diastole is available for all functions of the University of Missouri-Kansas City, including retreats, recitals, lectures, continuing education, committee and staff meetings, journal clubs, reunions, study groups, luncheons, dinners and social gatherings.

Pulse pressure is the difference between systolic and diastolic pressure.

There is normally a decrease in systolic pressure during inspiration; when that difference is greater than 10 mmHg, it is called pulsus paradoxus.

The most significant advances recently have been in our understanding of how the rest of the body adapts to the dysfunction of the heart in an attempt to correct and counteract these changes.
The issue in treatment is what are the relative percentages of diastolic or systolic dysfunction in each particular person with heart failure.
This is heavily reflected in our ability to treat heart failure, with the most known treatments directed to systolic dysfunction and the least known treatments for diastolic dysfunction.

Listening to the chest with a stethoscope (auscultation) may show lung crackles and may show abnormal or distant heart sounds.
Restrictive cardiomyopathy refers to a group of disorders in which the heart chambers are unable to fill with blood properly because of stiffness of the heart.
In restrictive cardiomyopathy, the heart is normal in size or only slightly enlarged, but it cannot relax normally during diastole (that is, the time between heartbeats in which the blood returns from the body to the heart).
