A grade 4 murmur is best described as what?

• A. Loud with palpable thrill
• B. Faint murmur
• C. Moderately loud with no thrill
• D. Loud with stethoscope completely off the chest

Answer: (A)

A grade 4 murmur is characterized by a loud sound heard with the stethoscope on the chest, accompanied by a palpable thrill felt on the chest wall. The murmur’s loudness places it higher on the grading scale, and the thrill—an actual vibration you can feel—distinguishes it from a grade 3 murmur, which is loud but without a palpable thrill. The presence of a thrill indicates more vigorous turbulent flow, usually from notable valvular pathology. In contrast, a faint murmur would be a lower grade, a moderate loudness with no thrill describes grade 3, and a murmur so loud that you’d hear it with the stethoscope off the chest points to grade 5 or 6.
