Electrocardiogram (ECG)
In the Cardiology department an electrocardiogram (ECG) is usually the first test carried out. The ECG gives the doctor a lot of information about the electrical activity of your heart muscle. This test also shows other abnormalities affecting the heart muscle, such as thickening, lack of oxygen and presence or absence of scars from a previous heart attack.
Exercise test or cycle test
The exercise test (or cycle test) is the commonest type of stress test and is initially used to identify significantly narrowed arteries in the heart.
Holter monitoring
A Holter monitor is a wearable device that records the electrical activity of your heart for 24 (or 48) hours while you are carrying out your everyday activities. Basically, it is an electrocardiogram (ECG) covering a period of 24 (or 48) hours. It is mainly used to screen for heart rhythm problems.
24-hour blood pressure measurement
This test is used to measure your blood pressure over a 24-hour period. This is done using an automatic blood pressure meter which is applied by the nurse during the consultation. This allows the doctor to have a better understanding of the blood pressure changes during the day and night. It is also easy to calculate the average blood pressure to check whether drug treatment is needed or should be adjusted.
FFR measurement or FFR-CT
An FFR measurement is a test for narrowing of the coronary arteries. FFR stands for ‘Fractional Flow Reserve' and measures the volume of oxygen-rich blood that flows through your coronary arteries.
Transthoracic echocardiogram
An echocardiogram (echo or TTE) provides images of your heart using ultrasonic sound waves. This is the commonest non-invasive method used to obtain images of the heart, and it enables the doctor to make the right diagnosis.
Transoesophageal echocardiogram (oesophageal echo)
In a transoesophageal echocardiogram the cardiologist uses a probe which is placed behind your heart via your oesophagus. The advantage of an oesophageal echo is that your organs which are close to the oesophagus can be imaged much more clearly in comparison with a transthoracic echocardiogram. Your heart and aorta and also the smaller structures in the heart like the atria, major blood vessels and the mitral and tricuspid valves can then be studied.
Coronary CT scan
A coronary CT scan is often used by doctors to refine a diagnosis. This test involves taking pictures of the coronary arteries, heart muscle and aorta to identify narrowed arteries or congenital abnormalities. UZ Brussel has special expertise in this area and has the latest new scanner in the sector.
Magnetic resonance (MR) imaging
Magnetic resonance (MR) imaging is sometimes used by doctors to refine a diagnosis. This test is particularly suitable for assessing the composition and function of the heart muscle itself. It also makes it possible to obtain better images of congenital heart abnormalities and certain abnormalities affecting blood vessels and heart valves.
