  2. Heart sounds - Wikipedia

    en.wikipedia.org/wiki/Heart_sounds

    First heart sound: caused by atrioventricular valves – Mitral (M) and Tricuspid (T). Second heart sound caused by semilunar valves – Aortic (A) and Pulmonary/Pulmonic (P). Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the ...

    en.wikipedia.org/wiki/Heart_murmur

    In severe cases, obliteration of the S2 heart sound may occur. Stenosis of Bicuspid aortic valve is like the aortic valve stenosis heart murmur. But, one may hear a systolic ejection click after S1 in calcified bicuspid aortic valves. Symptoms tend to present between 40 and 70 years of age. Mitral regurgitation is a holosystolic murmur. One can ...

    en.wikipedia.org/wiki/Wiggers_diagram

    A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century. [1][2] In the Wiggers diagram, the X-axis is used to plot time subdivided into the cardiac phases, while the Y-axis typically contains the following on a single grid: The Wiggers diagram ...

  5. Diastolic heart murmur - Wikipedia

    en.wikipedia.org/wiki/Diastolic_heart_murmur

    Diastolic heart murmur. Auscultogram from normal and abnormal heart sounds. 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.

  6. Mitral stenosis - Wikipedia

    en.wikipedia.org/wiki/Mitral_stenosis

    Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. [1] It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm 2 during diastole. Any decrease in area below 2 cm 2 causes mitral stenosis.

  7. Systolic heart murmur - Wikipedia

    en.wikipedia.org/wiki/Systolic_heart_murmur

    Systolic heart murmur. Auscultogram from normal and abnormal heart sounds. Systolic heart murmurs are heart murmurs heard during systole, [1][2][3] i.e. they begin and end between S1 and S2. Many involve stenosis of the semilunar valves or regurgitation of the atrioventricular valves.

  8. Valvular heart disease - Wikipedia

    en.wikipedia.org/wiki/Valvular_heart_disease

    See media help. Valvular heart disease is any cardiovascular disease process involving one or more of the four valves of the heart (the aortic and mitral valves on the left side of heart and the pulmonic and tricuspid valves on the right side of heart). These conditions occur largely as a consequence of aging, [1] but may also be the result of ...

  9. Heart click - Wikipedia

    en.wikipedia.org/wiki/Heart_click

    Heart click. With newer, non-invasive imaging techniques, the origin of other, so-called adventitial sounds or heart clicks has been appreciated. These are short, high-pitched sounds. [citation needed] The mitral valve in cases of mitral stenosis may open with an opening snap[1][2] on the beginning of diastole.
