Heart Murmur

Murmur or bruits are abnormal sounds heard in various parts of the vascular system. The 2 terms are used interchangeably, though murmur is more used to denote noise heard over the heart than other vessels. A heart murmur is the sound of blood flow turbulence in the heart.

Murmur is an abnormal sound produced in cardiovascular system by abnormal (increased) flow through a normal opening or normal blood flow through an abnormal opening. Heart murmur duration refers to the portion of systole or diastole that the murmur occupies. Terms used include short and long. Murmurs lasting throughout systole are referred to as holosystolic or pansystolic. A murmur is due to turbulence of blood flow and can, at times, encompass all of systole or diastole. It isn’t a disease and does not require treatment. But some murmurs indicate an underlying condition. That condition may be treated by healthcare providers.
