The “lub dub” sound of your heartbeat is CLOSING of the valves, not opening! 🫀✨ 🔊 S1 = “Lub” Happens when the atrioventricular (AV) valves close — that’s the tricuspid and mitral valves shutting after blood flows from the atria to the ventricles. 🔊 S2 = “Dub” Occurs when the semilunar valves (aortic and pulmonic) close — right after the ventricles have pumped blood out to the body and lungs. 💡Lub = start of systole 💡Dub = start of diastole #cardiaccycle #heartsounds #stethoscope #S1 #lubdub

Heart sounds (lub dub) explained and made easy. If you've ever wondered what makes that "lub dub" sound that you hear when auscultating a patient's heart sounds, it is the sound of the heart valves! The first sound (lub) is S1, and this is the closure of the tricuspid and mitral (bicuspid) valves. The next sound (dub) is S2 and represents the closure of the pulmonary and aortic valves. #nursing #nursingschool #heart #stethoscope #nurse #nurses #nursingstudent #study #education | Registerednurser
