What do you mean by auscultatory area ?
Auscultation which is the medical term used by professionals by using stethoscope for listening the heart sounds.

Why do you want to know this ?
Abnormal sounds may indicate the problem in

- Heart and Blood vessels
Common causes of abnormal sounds in heart
*Hypertension
*Aortic stenosis
Ischemic Heart disease ,etc....


Auscultation important ?
Auscultating the heart you can know about basic theme of what happening in body, if you heard something wrong like a murmurs you have to go for additional testing.
Auscultation will be an excellent primary prevention against certain medical conditions.
without doing cardiac auscultation your physical examination should not be completed.
 
The four standard points of auscultation for the heart are:
  • Aortic – on the patients right side of the sternum.
  • Pulmonary – on the left-hand side of the patients's sternum.
  • Tricuspid – in the fourth intercostal space, along the lower-left border of the sternum.
 
The purpose of auscultation of the heart is to characterize heart sounds and murmurs. (See "Examination of the precordial pulsation" and "Examination of the arterial pulse" and "Examination of the jugular venous pulse".) This topic will review the auscultation of heart sounds.
 
Standard sites for auscultation

- Mitral area - left fifth intercostal space, mid-clavicular line. This is where the mitral valve sounds are best auscultated; - Tricuspid area - left fourth intercostal space, just lateral to the sternum.
 
Auscultation of the heart sounds with a stethoscope is a cornerstone of physical medical exams and a valuable first-line tool to evaluate a patient. Some sounds are very characteristic of significant pathological lesions that have major pathophysiological consequences, and these first present on auscultation.
 
"Erb's point" is the fifth point of auscultation for the heart exam, located in the third intercostal space close to the sternum. ... Erb's focus on neurology suggested that the auscultation point may have been confused with other points in the neck named after Erb.
 
For example, the S1 heart sound — consisting of mitral and tricuspid valve closure — is best heard at the tricuspid (left lower sternal border) and mitral (cardiac apex) listening posts. Timing: The timing can be described as during early, mid or late systole or early, mid or late diastole.
