Murmurs are described by timing, intensity, quality, pitch and radiation. Which option lists these descriptors?

• A. Timing, intensity, quality, pitch and radiation
• B. Color, tempo, duration, and direction
• C. Rate, rhythm, axis, and QRS duration
• D. Location and inspiratory variation

Answer: (A)

Murmur description hinges on five attributes that guide how we characterize and differentiate murmurs: when it occurs in the cardiac cycle (timing), how loud it is (intensity), what the sound feels like (quality), the pitch of the sound (pitch), and where it radiates or is best heard (radiation). The set that lists exactly these five descriptors matches the standard way clinicians describe murmurs, so it is the best choice. Timing tells you whether the murmur is systolic, diastolic, or continuous, and whether it has early, mid, or late components, which helps narrow the valve or mechanism involved. Intensity reflects how loud the murmur is, which is often graded and can provide a rough sense of severity or flow. Quality describes the character of the sound—harsh, blowing, musical, or rumbling—which can hint at the underlying pathophysiology. Pitch indicates whether the murmur is high or low in frequency, aiding differentiation between lesions that produce different flow characteristics. Radiation describes where the sound travels beyond its point of maximal intensity, such as toward the carotids or axilla, aiding identification of the lesion’s origin. Other options mix in descriptors that aren’t standard for murmurs (like color, tempo, or direction) or pull in ECG-related terms (rate, rhythm, axis, QRS duration), or focus on location and inspiratory variation alone, which doesn’t capture the full, commonly taught set.
