Which term describes the regular pattern or sequence of heartbeats or breathing?

• A. Rhythm
• B. Rate
• C. Oximetry
• D. Metabolism

Answer: (A)

Rhythm is the regular pattern or sequence of heartbeats or breathing. It describes how the beats or breaths follow one another over time, with even spacing and a predictable cadence. When rhythm is steady, the intervals between beats or breaths are consistent; irregular rhythm can signal a problem that may need medical attention. Rate, by contrast, means how fast these events occur—the number of beats or breaths per minute—rather than the pattern itself. Oximetry is the measurement of blood oxygen saturation, not the sequence of beats or breaths. Metabolism refers to the body's chemical processes and energy production, not the rhythm of heartbeats or breathing.
