Innocent Murmur C26 case includes text, audio and visualization

This is an example of an innocent murmur. This type of murmur is seen with non-cardiac conditions such as pregnancy, hyperthyroidism, exercise and anemia. When these are treated appropriately the systolic murmur disappears. The murmur is heard in early systole, is of short duration and has a frequency range of 120Hz to 250Hz. It is best auscultated in the pulmonic area and increases in intensity with inspiration. It can be heard with either the bell or diaphragm. In this example S1 and S2 are normal. Diastole is silent. The short duration and mid-range frequency characterize an innocent murmur.
