Auscultation is performed for the purposes of examining the circulatory and respiratory systems (heart and breath sounds), as well as the alimentary canal. The term was introduced by René Laennec. The act of listening to body sounds for diagnostic purposes has its origin further back in history, possibly as early as Ancient Egypt.
The aortic area, pulmonic area, tricuspid area and mitral area are areas on the surface of the chest where the heart is auscultated. [6] Heart sounds result from reverberation within the blood associated with the sudden block of flow reversal by the valves closing.
The valve areas are palpated for abnormal pulsations (palpable heart murmurs known as thrills) and precordial movements (known as heaves). Heaves are best felt with the heel of the hand at the sternal border.
An accurate diagnosis remains challenging for various reasons including noise, high heart rates, and the ability to distinguish innocent from pathological murmurs. Properly performed, the auscultatory examination of the heart is commonly regarded as an inexpensive, widely available tool in the detection and management of heart disease. [10]
The stethoscope is a medical device for auscultation, or listening to internal sounds of an animal or human body.It typically has a small disc-shaped resonator that is placed against the skin, with either one or two tubes connected to two earpieces.

The National Heart, Lung and Blood Institute lists vegetables such as leafy greens — including spinach, collard greens, kale and cabbage — plus broccoli and carrots as a key part of a heart ...
The triangle of auscultation is useful for assessment using a pulmonary auscultation and thoracic procedures. [1] Due to the relative thinning of the musculature of the back in the triangle, the posterior thoracic wall is closer to the skin surface, making respiratory sounds audible more clearly with a stethoscope.
