So Quick and non-inasive test using ultrasonography that obtains information about the heart size, pump function, valve function and large blood vessels. Classically, this is done with an ultrasound probe and gel on the chest (transthoracic).

In 2017, the Echocardiography Lab of AZ Turnhout has obtained accreditation from the European Society of Cardiology

3D echocardiography

We have the possibility of 3D imaging, in which valve structures and congenital heart problems can be better assessed.

Stress echocardiography

Under the administration of intravenous medication, the heart is artificially stimulated to see if there are certain segments of reduced blood flow.
This study requires specific preparation.

This can also be performed during physical stress, i.e. supine bicycle exercise.

Transophageal echocardiography (TEE)

Transesophageal echocardiography (TEE) is a test that produces pictures of your heart. TEE uses high-frequency sound waves (ultrasound) to make detailed pictures of your heart and the arteries that lead to and from it. Unlike a standard echocardio, the echo transducer that produces the sound waves for TEE is attached to a thin tube that passes through your mouth, down your throat and into your esophagus. Because the esophagus is so close to the upper chambers of the heart, very clear images of those heart structures and valves can be obtained.

Bicycle stress test



During physical effort the heart rate and blood pressure are monitored, with continuous ECG reading, to obtain information about possible problems of blood flow at the level of the coronary arteries, or arrhythmias. Depending on the physical fitness , a bicycle stress test takes an average of 5 to 15 minutes.








Similar to a cycling test, but additional information is obtained by allowing the patient to breathe in a mask. Gas analysis measures oxygen uptake and determines, among other things, the anaerobic threshold for exertion. Useful test in unexplained shortness of breath, for athletes, and in heart failure.









To continuously monitor the heart rhythm in the home situation, 3 electrodes are applied to the chest. All normal activities can be carried out, except for swimming, showering or bathing. Is classically done for 24 or 48 hours. Afterwards, the timing of any symptoms can be correlated with the heart rhythm at that time.





Event recorder



To Device for long term (up to 3 weeks) rhythm registration. The patient can activate a button himself at the time of symptoms so that this 'event' is stored in the memory of the device. The electrodes can be removed if desired in order to shower.





24u ambulatory blood pressure



Portable, calibrated blood pressure monitor with custom cuff that takes measurements of blood pressure for 24h, day and night. Useful to detect the so-called 'whitecoat effect', to get an idea about the effect of medication, or in the case of dizziness symptoms where low blood pressure is suspected.





Tilt test



Tilting table test, in which the patient is buckled in a lying position, then the table is set upright to 60°, and where the patient must then try to stand up for 45 minutes. Test for the autonomic (involuntary) nervous system that regulates blood pressure and heart rate; done in patients with repeated syncopes (loss of consciousness). For this test you must be at least 4 hours fasting.





Pacemaker / ICD check



Any type of pacemaker or defibrillator (ICD) can be interrogated in our service. This happens routinely after implantation, and if you suspect any problems or depletion of the battery. The analysis is done wirelessly using an external programmator. For some types of devices, a wireless router can be installed at home so data are sent to our department every day which allows for resolving any problems quickly.





Cardiac catheterization



Here, classically under local anaesthetic, a plastic tube is inserted through the artery in the groin or in the wrist, along which a catheter is performed to the heart. Through the catheter and injection of contrast dye, the left heart chamber, aorta and coronary arteries can be visualised in detail. Uses X-rays. Patients who are allergic to iodine (contrast dye) should report this in advance!

In the case of right heart catheterization, pressures are measured in the ventricles and lung circulation, which is especially useful for valve problems or heart failure. This examination is done by canulating a vein in the groin, usually in combination with the left heart catheterization described above.

The procedure is done via an admission (minimum 1 overnight stay).
