Published	10/17/2023	In physiological heart splitting, {{c1::mitral}} valve closure is louder than {{c1::tricuspid}} valve closure
Published	10/17/2023	S2 has a slightly {{c1::higher}} pressure and pitch when compared to S1
Published	10/17/2023	The {{c1::aortic}} valve closes before the {{c1::pulmonary}} valve, and inspiration {{c2::accentuates}} this split

Published	10/17/2023	In aortic stenosis, the LV is at {{c2::higher::higher vs. lower}} pressure because of the narrowing of the aortic valve, causing a {{c1::crescendo-dec…
Published	10/17/2023	In aortic stenosis, the more stenosis you have, the {{c1::higher}} pressure the LV is going to be which means that the pressure difference between the…
Published	10/17/2023	Aortic regurgitation is a {{c1::diastolic}} murmur
Published	10/17/2023	{{c1::Aortic regurgitation::what condition?}} is when the aortic valve can't catch the ejected blood, so the blood wants to flow from the {{c2::high::…
Published	10/17/2023	Aortic regurgitation presents with a {{c1::decrescendo::describe it}} murmur since there is a {{c1::greater pressure difference}} between the aorta an…
