Which phrase is associated with tricuspid valve murmurs?

• A. Precordial Rock
• B. Isovolumetric contraction
• C. Ejection click
• D. A wave sound

Answer: (A)

Describing murmurs relies on auscultation characteristics and where the sound is best heard. For tricuspid valve murmurs, clinicians often use terms that capture the murmur’s vibration and how it feels or sounds over the precordium. The phrase “precordial rock” conveys a coarse, vibrating quality of the murmur heard along the left lower sternal border that can give a rocking sensation in the chest with respiration. This makes it a good fit for tricuspid murmurs, which are typically heard best at the left lower sternal border and can have a distinctive, vigorous quality. In contrast, isovolumetric contraction refers to a brief cardiac interval with no forward flow, so it’s not associated with a murmur. An ejection click arises from leaflet opening of semilunar valves or congenitally abnormal valves, not from tricuspid murmurs. An A wave sound describes a component of the jugular venous pulse, not a murmur descriptor.
