- EKG or ECG
ECG is an English abbreviation of Electrocardiogram. In Thai, it is called u0e01u0e32u0e23u0e15u0e23u0e27u0e08u0e04u0e25u0e37u0e48u0e19u0e44u0e1fu0e1fu0e49u0e32u0e2bu0e31u0e27u0e43u0e08. It is the diagnosis in the form of electrocardiogram. Conductive sheets are placed on the chest to catch the electric current, which will be printed in the graph paper. A consistent signal shows that the heart is working normally. However, if there are the differences in some points of the electric signal, it might show that some areas of the heart are injured or destroyed. This type of procedure is not complicated and can provide a general diagnosis.

- Exercise Stress Test
The exercise stress test is similar to ECG in which the chest will be attached with lead sheet. Your vital signs will be recorded while exercising, such as walking on treadmill or riding stationary bike. Exercise can increase the rate of heartbeat and high blood pressure. The test is used to measure the response of the heart towards the physical stress, such as abnormality of electric current in the body, the volume of blood that flows to the cardiac muscles, and the cardiac muscles that respond to the exercise.

- Blood Enzyme Tests
Cardiac enzymes are the substance in the cardiac muscular cell. When the heart is destroyed, the enzyme will be released into the bloodstream. This method of blood test will show the level of enzyme that increases when having a heart attack.

- Echocardiogram
An echocardiogram uses high frequency to pick up the movement of the heart. The doctor will study the images to measure and identify the function and structure of the heart.

- Radionuclide Scan
Radionuclide scan is the diagnosis by injecting radiation into the blood stream that flows into the heart. A special camera will take pictures of the heart and show them on a screen for the doctor to see any malfunctioning of your heart.

- Cardiac Catheterization
Cardiac catheterization is an x-ray examination by the specialist. A small catheter will be inserted into the blood vessel at the groin that flows to the heart. A special colored substance will be injected into the catheter. Then, the constricted or blocked blood vessel can be found from the x-ray screen.
