Cardiac Diagnostic Services

Resting Electrocardiogram (ECG)

Resting ECG can observe whether there is any abnormality in the “resting state” of the heart, such as arrhythmia, atrial and ventricular hypertrophy, or myocardial hypoxia. However, some people do not experience myocardial hypoxia during rest. Therefore, cardiologists will arrange “exercise ECG” examination according to patients’ conditions. The examination let the patient run on a treadmill, and observe the changes in the patient’s cardiopulmonary function, blood pressure and heartbeat as the speed or slope changes.

Exercise ECG (Treadmill Test)

Exercise electrocardiogram is to increase the burden on the heart and increase the oxygen demand during exercise, in order to evaluate whether the heart has myocardial hypoxia, and thus understand whether the coronary arteries are significantly narrowed. We can detect coronary heart disease through exercise ECG, and treat it early to prevent myocardial infarction and sudden death.

24-hour ECG (Holter Monitor)

24-hour ECG is used to detect arrhythmia (such as abnormal heartbeat, too fast, too slow, etc.). It is absolutely safe. The recording instrument is attached to the body for continuous recording over a longer period of time, ranging from 48 to 72 hours. The portable heart rhythm recorder can intermittently record the patient’s heart rhythm in several weeks, which is very helpful for diagnosing patients with infrequent symptoms.

Cardiac Ultrasound (Echocardiogram)

Cardiac Ultrasound is an important modality for the examination of the heart. This examination can evaluate the structure and function of the heart, understand the size and contraction of the heart, and judge the activity of the heart valves. Color ultrasound and Doppler blood flow measurement can determine the direction and velocity of blood flow in the heart vessels and can see whether the coronary artery is narrowed, and can also detect whether there is a heart valve defect, providing diagnosis and evaluation of the cardiovascular functions for patients with coronary artery disease and the general public. Echocardiogram has a high diagnostic value.
