Abnormal Heart Sounds Normally, the heart produces two sounds — S1 and S2, known as lub-dub, caused by valve closure. When the heart is abnormal, extra or altered sounds may be heard. 🔹 Heart Murmur A murmur is a whooshing sound caused by turbulent blood flow, often due to valve stenosis, valve regurgitation, or congenital heart defects. 🔹 S3 Gallop This low-pitched sound occurs after S2 and indicates increased ventricular filling, commonly seen in heart failure or volume overload. 🔹 S4 Gallo

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
