How to listen to heart sounds in 20 MINUTES| What You Need to KNOW
Dr. Adeleke Adesina, DO・2 minutes read
Listening to heart sounds requires understanding the chest anatomy and targeting specific regions for each valve, such as the aortic, pulmonic, tricuspid, and apex areas. S1 and S2 are normal heart sounds, while S3 and S4 can indicate heart conditions like heart failure or left ventricular hypertrophy, with S4 resembling "Tennessee" and requiring further examination for complexities in heart murmurs.
Insights
- Practice improves clarity in listening to heart sounds, while knowledge of chest anatomy is essential beforehand.
- Different heart regions correspond to specific valve locations, with S3 and S4 sounds indicating potential heart pathologies like heart failure or left ventricular hypertrophy, requiring a deep understanding for accurate diagnosis.

Deciphering Heart Sounds: Anatomy and Listening Techniques
- Heart sounds can be confusing to listen to, but with practice, it becomes clearer.
- Understanding the anatomy of the human chest is crucial before listening to heart sounds.
- The chest consists of clavicles, manubrium, sternum, ribs, and intercostal spaces.
- The heart has four valves: tricuspid, mitral, aortic, and pulmonary.
- To listen to heart sounds, specific regions on the chest are targeted based on valve locations.
- The aortic region is between the second and third intercostal space on the right side.
- The pulmonic region is on the left upper sternal border.
- The tricuspid region is on the left lower sternal border.
- The apex, where the mitral valve is heard, is between the fifth and sixth intercostal space.
- Heart sounds S1 and S2 are normal, while S3 and S4 indicate potential pathologies like heart failure or hypertension.

Decoding Heart Sounds for Diagnosis
- S4 is a heart sound that is close to S1, distinct from S3 and S2, often resembling the word "Tennessee" when heard, indicating left ventricular hypertrophy.
- Understanding S1, S2, S3, and S4 heart sounds is crucial in diagnosing heart conditions; detecting S4 can suggest left ventricular hypertrophy, while S3 may indicate heart failure, with further complexities in heart murmurs explained on a recommended website.
