Early detection of cardiovascular diseases is important as it enables suitable lifestyle changes or treatments that can prevent further health complications. There are a number of several tests available to diagnose cardiovascular diseases effectively, such as electrocardiogram (ECG)1 and cardiac stress tests.
An ECG is a painless, non-invasive test commonly used by cardiologists to record the electrical activity of a person’s heart at rest. This data, which provides information about a person’s heart rate and rhythm, can help a cardiologist to determine2:
A standard ECG test - also known as resting ECG - takes approximately 5-10 minutes and uses electrodes that are attached to a person’s chest, arms and legs whilst lying down to detect electrical current generated by the heart. No movement is allowed during the test, as electrical impulses generated by a person’s muscles can interfere with those generated by the heart.
Ambulatory ECGSeparately, ambulatory ECG uses electrodes connected to a portable machine - also known as a Holter machine - to record the electrical activity of a patient’s heart over a period of 24 hours or more2.
At Pantai Hospital, which has been accredited by the Malaysian Society for Quality in Health (MSQH) for service quality excellence, our cardiologists may choose to perform ECG for patients who present with symptoms of cardiovascular problems. These include:
It is important to note that the type of ECG recommended by our cardiologists will usually depend on a person’s symptoms. For instance, an ambulatory ECG may be prescribed for those who experience symptoms of heart disease in unpredictable, random episodes.
The methods used in a resting ECG and cardiac stress test are similar in nature. However, unlike a resting ECG, a cardiac stress test requires a person to pedal a stationary bike or walk on a treadmill for a specific amount of time, or until they feel exhausted3.
The main reason a cardiologist would recommend a cardiac stress test is to determine how well your heart handles work. This objective is relatively different from that of a resting ECG, which is used to detect the activity of a person’s heart at rest.
It can also show if blood supply is reduced in the arteries that supply the heart and this helps a cardiologist to identify the exercise intensity level that is appropriate for a patient.
If you suspect that you may be at risk of a cardiovascular disease, do not hesitate to contact our Heart Centre at Pantai Hospital to schedule an appointment today.
