Split S2. Wiggers diagram of various events of a cardiac cycle, with 2nd heart sound at bottom. A split S2 is a finding upon auscultation of the S2 heart sound. [1] It is caused when the closure of the aortic valve (A 2) and the closure of the pulmonary valve (P 2) are not synchronized during inspiration. The second heart sound (S2) is caused ...
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 ...
Cardiology. Pulsus alternans is a physical finding with arterial pulse waveform showing alternating strong and weak beats. [ 1] It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis. The condition is relatively rare, and patients with the greatest risk for developing pulsus alternans include those ...
The fourth heart sound or S 4 is an extra heart sound that occurs during late diastole, immediately before the normal two "lub-dub" heart sounds (S 1 and S 2).It occurs just after atrial contraction and immediately before the systolic S 1 and is caused by the atria contracting forcefully in an effort to overcome an abnormally stiff or hypertrophic ventricle.
The left atrial appendage is a pouch-like structure located in the upper part of the left atrium. [ 1] Left atrial appendage occlusion (LAAO) is an alternative therapy to oral anticoagulation in a certain subset of patients with atrial fibrillation. Atrial fibrillation is characterized by an irregular and uncoordinated pumping function of the ...
Left axis deviation. The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. In electrocardiography, left axis deviation (LAD) is a condition wherein the mean electrical axis of ventricular contraction of the heart lies in a frontal plane direction between −30° and −90°.
Cardiology. A myxoma is a rare benign tumor of the heart. Myxomata are the most common primary cardiac tumor in adults, and are most commonly found within the left atrium near the valve of the fossa ovalis. Myxoma may also develop in the other heart chambers. [1] The tumor is derived from multipotent mesenchymal cells. [1]
