Explanation
A. Stress test: A stress test, or exercise stress test, involves monitoring the heart's activity with an EKG while the patient exercises on a treadmill or stationary bike. This test assesses how the heart performs under physical stress.
B. Holter monitor: A Holter monitor is a portable EKG device worn by the patient for 24-48 hours to continuously record heart activity in their daily life, not during exercise.
C. Echocardiogram: An echocardiogram uses ultrasound to visualize the heart's structures and is not performed while the patient is exercising.
D. Cardiac event monitor: A cardiac event monitor is used to record heart activity when the patient experiences symptoms, typically worn for weeks to months, and is not specifically for exercise testing.
