These reflect turbulence that can be caused by high flow rates, damaged valves, dilated chambers or vessels, or backward flow through a regurgitant valve. _____ are described by timing, intensity, quality, pitch and radiation.

• A. Murmurs
• B. Rubs
• C. Clicks
• D. Bruits

Answer: (A)

Turbulent blood flow within the heart creates murmurs, which are defined by when they occur in the cardiac cycle (timing), how loud they are (intensity), the character of the sound (quality), the pitch, and where the sound radiates (radiation). This turbulence can arise from high flow states, damaged or stenotic/dilated valves, dilated chambers or vessels, or backward flow through a regurgitant valve. Those descriptors—timing, intensity, quality, pitch, and radiation—are classic for murmurs, making them the best match for the statement. Pericardial rubs are scratchy sounds tied to pericardial inflammation and described more by location and timing relative to the heartbeat; clicks are brief, often related to valve opening or prosthetic devices; bruits are vascular sounds described by location and quality of flow, not the full set of murmur descriptors.
