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

Common systolic murmurs: • Aortic stenosis — harsh crescendo-decrescendo at right upper sternal border • Mitral regurgitation — holosystolic blowing murmur at apex → radiates to axilla • Tricu
