Clarification of heart diseases


The electrocardiogram (ECG) records the electrical heart action by means of skin electrodes and is used in acute diagnostics but also in therapy monitoring of heart diseases.

Long-term ECG

This examination is used for patients who, for example, complain of palpitations, heart stuttering, fainting, dizziness, or collapse. Long-term ECG (24h, 48h, 7-day or 4 weeks) can be used to analyze arrhythmias. Some arrhythmias are harmless and do not require medical or interventional therapy. Others require further evaluation with imaging or other procedures, or therapy with medications, pacemakers, or catheter ablation.

24h blood pressure measurement

Since a single blood pressure measurement, especially in the presence of a healthcare professional, can show falsely high values (“white coat hypertension”), a 24-hour blood pressure measurement is often performed. In this case, the blood pressure is measured at regular intervals several times an hour over 24 hours using a device that is given to the patient at home. This allows a realistic and reliable assessment of the blood pressure situation.


Ergometry involves physical exertion on a bicycle or treadmill. Blood pressure and ECG are monitored. Ergometry is an important part of the diagnosis and follow-up of cardiovascular diseases. Ergometry is also used to better assess high blood pressure and cardiac arrhythmias. Another field of application of ergometry is preventive medicine and sports medicine. Spiroergometry can also be performed for special questions such as the clarification of shortness of breath or for training advice. In this case, the patient wears a mask with which the respiratory gases are measured. In addition, we also offer lactate performance diagnostics for athletes.

Tilt table examination

This examination is used to clarify unclear sudden loss of consciousness.

Pacemaker query

Our pacemaker consultation is available for patients with pacemakers, implantable defibrillators and special pacemakers for cardiac resynchronization therapy. Routine checks, reprogramming due to complaints or for medical reasons are performed here. The first wound checks after implantation of the devices also take place here.
