Term
Define "Auscultation"
Definition
Listening for sounds within the body, esp. from the chest, neck, or abdomen.
Term
Define "Frequency" (as it pertains to heart sounds)
Definition
The number of repetitions of a phenomenon in a certain period or within a distinct population, such as the frequency of heartbeat, sound vibrations, or a disease.
Term
Define "Holosystolic"
Definition
Relating to the entire duration of systole
Term
Define "Intensity"
Definition
A state of of increased force or energy, ie. volume
Term
Define "Listening Post"
Definition
A position on the body from which to listen or gather information
Term
Define "Non-Compliant" (as it pertains to heart sounds)
Definition
A decline in performance of one or both ventricles of the heart during the time phase of diastole
Term
Define "Pansystolic"
Definition
Throughout systole
Term
Define "Pitch"
Definition
That quality of the sensation of sound that enables one to classify it in a scale from high to low. It is dependent principally on frequency of vibrations
Term
Define "Diastolic Rumble"
Definition
A sound of some duration occurring during diastole. All diastolic murmurs imply some alteration of anatomy or function of the cardiovascular structures
Term
Define "Opening Snap"
Definition
A sharp, high-pitched click in early diastole, associated with the opening of the abnormal valve in cases of mitral stenosis.
Term
Define "Crescendo"
Definition
A gradual increase of intensity
Term

Definition
A gradual decrease of intensity
Term
Define "Bruit"
Definition

Term
Define "Gallop"
Definition

Term
Define "Murmur"
Definition
An abnormal sound heard on auscultation of the heart and adjacent large blood vessels Murmurs range in sound from soft and blowing to loud and booming and may be heard during systole, diastole, or both. A murmur does not necessarily indicate organic pathology, and heart disease may not be associated with the production of a murmur. Air in the lungs may simulate sounds similar to heart murmurs.
