Characteristics
of Systolic Murmurs |
Mid-Systolic
Ejection Murmurs
begin after the first heart sound when the ventricular pressure
is high enough to open the valves. As ejection increases and
decreases, so does the murmur

Found
in:
Aortic Stenosis
Pulmonary Valve Stenosis
Tetralogy of Fallot
Dilatation of the Proximal Pulmonary Artery
Atrial Septal Defect |
|
Holosystolic Regurgitant Murmurs
occupies all of systole and continues as long as there is a
sufficient pressure gradient across the incompetent orifice
to generate a regurgitant flow
|
|
Found
in:
Mitral Insufficiency
Tricuspid Insufficiency
Ventricular Septal Defect
Patent Ductus Arteriosus |
|
Early
Systolic Murmurs
begin with S1 rather than
after it. They end abruptly in early systole or mid-systole
and are characteristic of certain types of VSDs, mitral or tricuspid
regurgitation .
|
|
Found
in:
Small VSD without Pulmonary Hypertension
Large VSD with Pulmonary Hypertension
Septal Perforation due to Myocardial Infarct
Acute Severe Mitral Regurgitation |
|
Late
Systolic Murmurs
begins about one third or halfway into systole. It is due to
mitral insufficiency where the valve is competent during early
systole but prolapses into the LA in late systole .
|
|
Found
in:
Mitral Valve Prolapse Syndrome
Click-Murmur Syndrome |
|
Systolic
Arterial Murmurs
as a characteristic of peripheral vascular disease affecting
the larger arteries, to narrowing of the pulmonary artery and
its branches or coarctation of the aorta .

Found
in:
Pulmonary Artery Narrowing
Coarctation of the Aorta
Bicuspid Aortic Valve |
