Splitting S1 __link__ 〈95% FRESH〉

. Because these valves usually close almost simultaneously, they create one unified sound. Why Does it "Split"? A split occurs when there is a slight delay between the closure of these two valves. Normal Splitting: In roughly 40% to 70% of healthy individuals, the mitral valve closes slightly before the tricuspid valve, creating two audible "clicks" very close together. Auscultation: This is best heard at the lower left sternal border (the tricuspid area). It is often described as a "split" because the two components are distinct but very rapid. Clinical Significance While frequently benign, a split S1 can be associated with specific conditions that delay the electrical signal to the heart's right side: Right Bundle Branch Block (RBBB): A common cause where the electrical impulse to the right ventricle is delayed, causing the tricuspid valve to close later than usual. Tricuspid Stenosis: Narrowing of the tricuspid valve can also alter the timing or intensity of its closure. Ejection Sounds: Sometimes what sounds like a split S1 is actually an S1 followed by an early aortic ejection sound , which can occur in patients with aortic valve issues.
