Murmurs are graded on a scale of 1 to 6. Use the system outlined below to describe the intensity of a murmur:

• Grade I is a barely audible murmur.
• Grade II is audible but quiet and soft.
• Grade III is moderately loud, without a thrust or thrill.
• Grade IV is loud, with a thrill.
• Grade V is very loud, with a palpable thrill.
• Grade VI is loud enough to be heard before the stethoscope comes into contact with the chest.

When recording your findings, use Roman numerals as part of a fraction, always with VI as the denominator. For instance, a grade III murmur would be recorded as "grade III/VI."
