Understanding Heart Sounds: S1, S2, S3, S4, and Murmurs - A Comprehensive Guide

This comprehensive guide delves into the world of heart sounds, demystifying S1, S2, S3, S4, and murmurs. Understanding these sounds is essential for any aspiring nurse preparing for the NCLEX!
0:03 - Introduction
Discover the importance of distinguishing heart sounds and learn about S1, S2, S3, S4, and murmurs.
0:24 - Normal Heart Sounds: S1 and S2
Understand the love (S1) and dub (S2) sounds created when the mitral and tricuspid valves close during systole and when the aortic and pulmonic valves close during diastole.
1:13 - S3:
Learn about S3, a sloshing sound that can occur after S2 (dub). It is associated with fluid overload, often seen in conditions like heart failure or during late pregnancy.
2:06 - S4:
Explore S4, an extra heart sound that occurs before S1. Understand that detecting S4 may require an EKG and echo, and it's associated with stiff atria, often seen in conditions like hypertension or cardiomyopathy.
3:23 - Murmurs:
Understand that murmurs are caused by turbulent blood flow, creating a whooshing noise. They can be benign in children but may signal a problem in adults, often associated with regurgitation or stenosis.
