Cardiac Test Information

What are common initial screening test?

ECG (Electrocardiogram):

A simple test that detects and records the electrical activity of your heart. It shows how fast your heart is beating and whether it has a regular rhythm. It also shows the strength and timing of electrical signals as they pass through each part of your heart. An ECG can also show signs of a previous or current heart attack.


Is any preparation necessary?

No – no preparation is required for this examination. After checking in at the reception of Diagnostic Healthcare, you will be asked to lie down on your back. Electrodes will be affixed to each arm and leg and to your chest. This requires cleaning the site and, if necessary, shaving hair. You are usually required to remain still, and you may be asked to hold your breath for short periods during the procedure.


An exercise test (treadmill test):

Helps a doctor find out how well your heart handles work. As your body works harder during the test, it requires more oxygen, so the heart must pump more blood. The test can show if the blood supply is reduced in the arteries that supply the heart. It also helps doctors work out the kind and level of exercise appropriate for a patient.

Is any preparation necessary?

Yes – You will be asked to wear for the test comfortable shoes and loose clothing to allow exercise. You must not eat, smoke, or drink beverages containing caffeine or alcohol for 3 hours before the test.

After checking in at the reception of Diagnostic Healthcare, you will be hooked up to electrodes to monitor the heart. You will walk on an exercise treadmill while the electrical activity of your heart is measured, and blood pressure readings are taken. This will measure your heart’s reaction to your body’s increased need for oxygen.



Uses sound waves (ultrasound) to create a moving picture of your heart. Echocardiography provides information about the size and shape of your heart and how well your heart chambers and valves are working. The test can also identify areas of poor blood flow to the heart, areas of heart muscle that aren’t contracting normally, and previous injury to the heart muscle caused by poor blood flow.


Stress echocardiography:

Uses sound waves (ultrasound) to create a moving picture of your heart. Medication is used to increase your heart rate and show how your heart works under exertion. This test may be used to monitor your progress if you already have a known heart condition or in case a patient cannot cope with exercise.


24 Hours Tape(Holter monitoring) ECG / Blood Pressure:

A Holter monitor is a portable device for continuously monitoring the electrical activity of the heart for 24 hours or more. The monitor has electrodes, which you wear on your chest. These electrodes are very sensitive, and they can pick up the electrical impulses of the heart. The impulses are recorded by the Holter monitor and give a 24-hour record of your heart’s electrical activity. The record is interpreted by specialists at Diagnostic Healthcare and a result is performed. The same service is available to monitor your blood pressure for 24 hours.
