Friction rubs are frequently described as creaking or scratching but may sound like more common murmurs. This rub is often triphasic, with a systolic component and 2 components in quick succession during diastole (representing early diastolic filling and atrial systole). The rub may also have 1 component only, in ventricular systole.
