What it shows:
Echocardiography is essential for diagnosing heart failure, valve disorders, and cardiomyopathy.
A stress test monitors your heart while you exercise, usually on a treadmill or stationary bike.
What it shows:
If you cannot exercise, a medication-based (pharmacological) stress test may be done instead.
A Holter monitor is a portable ECG device worn for 24–48 hours to continuously record heart rhythms.
What it shows:
