Auscultation (based on the Latin verb auscultare "to listen") is listening to the internal sounds of the body, usually using a stethoscope.Auscultation is performed for the purposes of examining the circulatory and respiratory systems (heart and breath sounds), as well as the alimentary canal.
Heart sounds result from reverberation within the blood associated with the sudden block of flow reversal by the valves closing. Because of this, auscultation to determine function of a valve is usually not performed at the position of the valve, but at the position to where the sound waves reverberate. [citation needed]
Upon auscultation, this sign is an extra heart sound of to-and-fro character, typically with three components, two systolic and one diastolic. [1] It resembles the sound of squeaky leather and often is described as grating, scratching, or rasping. The sound seems very close to the ear and may seem louder than or may even mask the other heart ...
The cardiovascular examination is a portion of the physical examination that involves evaluation of the cardiovascular system. The exact contents of the examination will vary depending on the presenting complaint but a complete examination will involve the heart (cardiac examination), lungs (pulmonary examination), belly (abdominal examination) and the blood vessels (peripheral vascular ...
Heart murmurs are unique heart sounds produced when blood flows across a heart valve or blood vessel. [1] This occurs when turbulent blood flow creates a sound loud enough to hear with a stethoscope. [2] The sound differs from normal heart sounds by their characteristics. For example, heart murmurs may have a distinct pitch, duration and timing.
A gallop rhythm refers to a (usually abnormal) rhythm of the heart on auscultation. [1] It includes three or four sounds, thus resembling the sounds of a gallop.. The normal heart rhythm contains two audible heart sounds called S 1 and S 2 that give the well-known "lub-dub" rhythm; they are caused by the closing of valves in the heart.
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.
Auscultation employs a stethoscope to more easily hear various normal and abnormal sounds, such as normal heart beat sounds and the usual heart beat sound changes associated with breathing versus heart murmurs.
