<unk> s are unique<unk>  sounds produced when blood flows across a<unk>  valve or blood vessel. This occurs when turbulent blood flow creates a sound loud enough to<unk> with a stethoscope. Turbulent blood flow is not smooth. The sound differs from normal<unk>  sounds by their characteristics. For example,<unk> s may have a distinct pitch, duration and timing. The major way<unk> h care providers examine the<unk>  on physical exam is<unk>  auscultation. A<unk>  is a sign found during the cardiovascular exam.<unk> s are of various types and are important in the detection of cardiac and valvular pathologies (i.e. can be a sign of<unk>  diseases or defects). There are two types of<unk> s. A functional<unk>  or "physiologic<unk> " is a<unk>  that is primarily due to physiologic conditions outside the<unk> . Other types of<unk> s are due to structural defects in the<unk>  itself. Functional<unk> s are benign (an "innocent<unk> "). Most of the time<unk> s are normal variants. These type of<unk> s present at various ages. This is due to changes of the body with age. For example, chest size, blood presure, pliability or rigidity of structures. Normal variants are present without a cardiovascular problem.<unk> s may also be the result of various problems. For instance, narrowing or leaking of valves, or the presence of abnormal passages through which blood flows in or near the<unk> s caused by a disease process are pathologic<unk> s. Pathologic<unk> s may need evaluation by a cardiologist.<unk> s are frequently categorized by timing. These include systolic<unk> s, diastolic<unk> s, or continuous<unk> s. These differ in the part of the<unk> beat they make sound, during systole, or diastole. Yet, continuous<unk> s create sound throughout both parts of the<unk> beat. Continuous<unk> s are not placed into the categories of diastolic or systolic<unk> s. This article discusses information on<unk> s. It starts with what a<unk>  is and why they occur. Then the way in which one discovers a<unk>  with classification and interventions. Following this is conditions causing<unk> s by anatomy and timing. Last is an overview of diseases with<unk> s and management of<unk> s.
