In which laboratory are EKGs and stress tests typically performed?

• A. Cardiology Laboratory
• B. Radiology Department
• C. Pathology Laboratory
• D. Intensive Care Unit

Answer: (A)

Testing heart function with EKGs and exercise stress tests is best done in the cardiology laboratory because these procedures specifically monitor the heart's electrical activity and how it responds to increased workload, requiring specialized equipment and immediate interpretation by clinicians trained in heart care. The cardiology lab has ECG monitoring, treadmill or other stress-testing devices, and staff ready to respond to any abnormal findings. Radiology focuses more on imaging, pathology on tissues, and the ICU on critically ill patients; while some imaging stress tests may involve radiology, the routine setting for EKGs and standard stress testing is the cardiology lab.
