Diastolic heart murmurs are heart murmurs heard during diastole, [1] [2] [3] i.e. they start at or after S2 and end before or at S1. Many involve stenosis of the atrioventricular valves or regurgitation of the semilunar valves .
Most murmurs are normal variants that can present at various ages which relate to changes of the body with age such as chest size, blood pressure, and pliability or rigidity of structures. [3] Heart murmurs are frequently categorized by timing. These include systolic heart murmurs, diastolic heart murmurs, or continuous murmurs. These differ in ...
Heart murmurs are produced as a result of turbulent flow of blood strong enough to produce audible noise. They are usually heard as a whooshing sound. They are usually heard as a whooshing sound.

However, there has recently been a move towards the use of the fifth Korotkoff sound (i.e. silence) as the diastolic blood pressure, as this has been felt to be more reproducible. [9] For paediatrics, there has been controversy regarding whether to use auscultation of the fourth or fifth Korotkoff sound as an indicator of diastolic pressure ...
Anticoagulants: To prevent embolization.. Beta blockers: To block the effects of certain hormones on the heart to slow the heart rate.. Calcium Channel Blockers: Help slow the heart rate by blocking the number of electrical impulses that pass through the AV node into the lower heart chambers (ventricles).
Patients with mitral valve prolapse may have a mid-systolic click along with a murmur, referred to as apical late systolic murmur. [3] Early systolic clicks may also be present in some patients. [4] Aortic and pulmonary stenosis may cause an ejection click [5] immediately after S 1.
Duroziez's sign is a sign of aortic insufficiency. [1] It consists of an audible diastolic murmur which can be heard over the femoral artery when it is compressed with the bell of a stethoscope.
