Which are the six regions of the heart auscultated with both the bell and diaphragm?

• A. Aortic, Pulmonic, Erb's Point, Tricuspid, Tricuspid, and Mitral
• B. Aortic, Pulmonic, Erb's Point, Tricuspid, Mitral, and Aortic
• C. Aortic, Mitral, Tricuspid, Pulmonic, and Aortic
• D. Aortic, Pulmonic, Mitral, and Tricuspid only

Answer: (A)

Hearing with both the bell and the diaphragm lets you capture a wider range of heart sounds, so you examine multiple regions on the precordium. The six regions described in some teaching resources are Aortic, Pulmonic, Erb's Point, Tricuspid, Tricuspid (another listening spot along the left sternal border), and Mitral. The duplication of the Tricuspid area reflects counting two distinct tricuspid listening zones along the left sternal border. This arrangement accounts for using both stethoscope surfaces to detect different sound frequencies, and explains why that option is considered the best choice.
