Which term describes the exercise electrocardiography used to determine if the heart is receiving enough blood during exercise?

• A. Somatic tremor
• B. Standard limb lead
• C. Treadmill test
• D. T wave

Answer: (C)

The idea being tested is how we assess heart blood flow under stress. An exercise ECG done on a treadmill is called a treadmill test. In this test, the patient walks or runs on a treadmill while the ECG and blood pressure are continuously monitored. The workload is gradually increased to raise the heart’s oxygen demand. If the heart isn’t getting enough blood during that demand, signs of ischemia appear—such as chest discomfort, shortness of breath, or specific ECG changes like ST-segment depression—indicating possible coronary artery disease. Somatic tremor refers to muscle-related noise on the ECG rather than a test, standard limb leads are simply a setup for recording electrical activity, and the T wave is a portion of the ECG waveform that can change with ischemia but is not itself a stress-testing procedure.
