Grading volume of a murmur
Grading Volume of a Heart Murmurs: The experienced examiner should be able to give the murmur a grade according to its loudness: Grade 1 – very faint murmur which is only audible during prolonged auscultation Grade 2 – a faint murmur, immediately audible with a stethoscope Grade 3 – loud murmur with NO thrill Grade 4 – loud murmur WITH a thrill Grade 5 – loud murmur WITH a thrill, heard with only half of the stethoscope touching the chest Grade 6 – loud murmur WITH a thrill, heard WITHOUT the stethoscope touching the chest Top tip: Never describe a murmur as grade 1 or 2 in OSCE examinations as it is commonly accepted that only expert cardiologists can detect these murmurs! The grading system can be made easier by remembering that grade 4 and above requires the presence of a thrill.
