Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...

The Levine scaling system persists as the gold standard for grading heart murmur intensity. It provides accuracy, consistency, and interrater agreement which are essential for diagnostic purposes, particularly to distinguish innocent from pathological murmurs. Louder murmurs (grade ≥3) are more likely believed to represent cardiac defects ...

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.
Auscultation assessing lung sounds. A range of instruments and tools have been developed to assist nurses in their assessment role. These include: [ 17 ] the index of independence in activities of daily living , [ 18 ] the Barthel index , [ 19 ] the Crighton Royal behaviour rating scale, [ 20 ] the Clifton assessment procedures for the elderly ...
Computer-aided auscultation (CAA), or computerized assisted auscultation, is a digital form of auscultation. It includes the recording, visualization, storage, analysis and sharing of digital recordings of heart or lung sounds. The recordings are obtained using an electronic stethoscope or similarly suitable recording device.
Upon auscultation of an individual with mitral stenosis, the first heart sound is usually loud and may be palpable (tapping apex beat) because of increased force in closing the mitral valve. The first heart sound is made by the mitral and tricuspid heart valves closing. These are normally synchronous, and the sounds are termed M1 and T1 ...
