Murmurs are valuable in the diagnosis and differential diagnosis of heart disease. However, a murmur does not necessarily mean that there is heart disease, and there can be heart disease without a murmur. It should be consulted promptly.
According to the site where the murmur is produced with or without organic lesions, the murmur is divided into organic and functional. According to the clinical significance of murmurs can be divided into pathological murmurs and physiological murmurs (including harmless murmurs).
Organic murmurs refer to the presence of organic lesions at the site of murmur production, while functional murmurs include physiologic murmurs; murmurs produced by hemodynamic changes caused by systemic diseases; and murmurs caused by relative closure insufficiency or relative stenosis of cardiac pathological significance.
The latter is localized in the heart without organic lesions, but it and the organic murmur can be combined as a pathological murmur. It should be noted that a physiologic murmur must meet the following conditions: it is limited to systole, the heart is not enlarged, the murmur is soft, windy, and there is no tremor.
If a heart murmur is present, it is recommended to consult a hospital for further diagnosis and treatment.
