How do you classify a heart murmur?
- Timing refers to whether the murmur is a systolic or diastolic murmur.
- Shape refers to the intensity over time; murmurs can be crescendo, decrescendo or crescendo-decrescendo.
How is murmur loudness graded?
Under this system, absence of a heart murmur is graded 0/6. Murmurs that are clearly softer than the heart sounds are graded 1/6. Murmurs that are approximately equal in intensity to the heart sounds are graded 2/6. Finally, murmurs that are clearly louder than the heart sounds are graded 3/6.
