Explore common cardiac diagnostic tests, their purpose, and how to prepare.
A Holter monitor is a portable, battery-operated ECG device worn continuously for 24–48 hours. It captures heart rhythm throughout the day and night, including during sleep and activity.
An ECG records the electrical activity of the heart. It is one of the most common and quick cardiac investigations used worldwide to detect a wide range of heart conditions.
An echocardiogram is an ultrasound scan of the heart. It provides detailed images of the heart's chambers, valves, walls, and the major blood vessels attached to the heart.
A Treadmill Test (TMT), also called an Exercise Stress Test, evaluates how the heart responds to increased physical demand. It helps uncover problems that may not appear at rest.
