Which term is the recording of the entire ECG cycle?

• A. ST segment
• B. Tracing
• C. Treadmill test
• D. Somatic tremor

Answer: (B)

In ECG terms, the tracing is the complete recording of the heart’s electrical activity over one cycle, showing the P wave, QRS complex, and T wave in sequence. It’s the printed or digital display you review to assess rhythm and timing. The ST segment is only a portion of that waveform—the section between the QRS complex and the T wave. A treadmill test is an exercise-based assessment, not the recording itself, and somatic tremor refers to an artifact caused by muscle movement, not the entire ECG trace. So the tracing best describes the recording of the entire ECG cycle.
