WebbSplitting of S2, also known as physiological split, normally occurs during inhalation because the decrease in intrathoracic pressure increases the time needed for pulmonary pressure to exceed that of the right ventricular pressure. Webb12 sep. 2024 · It is caused by the displacement of thin, watery, protein-poor (transudative) interstitial fluid. Although it can affect any part of the body, pitting edema usually occurs in the legs, feet, and ankles due to venous insufficiency caused by congestive heart failure. The different types of split S2 can be associated with medical conditions: Split during inspiration: normal. (See above)Wide splitting: seen in conditions that delay RV emptying (pulmonic stenosis, right bundle branch block). Delay in RV emptying causes delayed pulmonic sound (regardless of breath); it is an … Visa mer A split S2 is a finding upon auscultation of the S2 heart sound. It is caused when the closure of the aortic valve (A2) and the closure of the pulmonary valve (P2) are not synchronized during inspiration. The … Visa mer During inspiration, the chest wall expands and causes the intrathoracic pressure to become more negative (think of a vacuum).
