Diastolic murmurs
Diastolic murmurs are always abnormal; most are early or mid diastolic, but they may be late diastolic (presystolic). Early diastolic murmurs are typically due to Aortic Regurgitation or A mitral or tricuspid murmur due to an atrial tumor or thrombus may be evanescent and may vary with position and from one examination to the next because the position of the intracardiac mass changes. Systolic murmurs may be normal or abnormal but diastolic murmurs are always abnormal.
