Answer:
8)Heart sounds are produced from a specific cardiac event such as closure of a valve or tensing of a chordae tendineae. Many pathologic cardiac conditions can be diagnosed by auscultation of the heart sounds. Note that heart sounds are discrete, short audible events from a specific cause — different from a heart murmur. A murmur is due to turbulence of blood flow and can, at times, encompass all of systole or diastole.
The main normal heart sounds are the S1 and the S2 heart sound. The S3 can be normal, at times, but may be pathologic. A S4 heart sound is almost always pathologic. Heart sounds can be described by their intensity, pitch, location, quality and timing in the cardiac cycle.
