So when you hear 'S2' at the mitral area, you are really hearing A2. Normally, P2 is soft and only heard at the pulmonic region (left parasternal, intercostal space 2), however even in this region A2 is louder. What causes the split second heart sounds? There are believed to be multiple causes for the physiologic splitting of S2.

The common causes of a loud S2 include high systemic (A2) or pulmonary (P2) pressures and closure of a prosthetic valve (usually in the aortic position). If the S2 is split, try to decipher which component is loudest.

The second heart sound (S2) is a short burst of auditory vibrations of varying intensity, frequency, quality, and duration. It has two audible components, the aortic closure sound (A2) and the pulmonic closure sound (P2), which are normally split …

2023年7月17日 · The regurgitant murmurs are mitral and tricuspid insufficiency. They are classically described as harsh, loud, holosystolic murmurs, which means the murmur lasts the entire duration of systole and covers up S2. The noise is due to the regurgitant flow through the incompetent valve.

2021年1月13日 · Heart murmur: sound due to turbulent blood flow in the heart; essential to identify during cardiovascular examination. Primary heart sounds: S1 (closure of mitral and tricuspid valves, marks start of ventricular systole); S2 (closure of aortic and pulmonary valves, marks end of ventricular systole).

What are the abnormalities of the heart sounds? FIRST HEART SOUND Quiet Cardiac tamponade (+ quiet S2)Long PR interval (1st degree heart block) Rheumatic mitral regurgitation Loud Mitral stenosis Short PR interval SECOND HEART SOUND Quiet Cardiac tamponade (+ quiet S1) Calcific aortic stenosis Aortic regurgitation Loud Systemic hypertension Pulmonary …

Like the S1 heart sound, the S2 sound is described regarding splitting and intensity. S2 is physiologically split in about 90% of people. The S2 heart sound can exhibit persistent (widened)...

2022年11月10日 · Fixed S2 splitting is associated with acute pulmonary hypertension, pulmonary stenosis, and pulmonary emboli. Fixed splitting of the second heart sound along with murmurs can indicate the presence of an atrial septal defect, a congenital heart defect.
