Clinic for Internal Medicine

Cardiology is the science of the heart and its functions. As cardiologists, we specialise in diseases that affect the heart and can impair its normal function.

We offer a comprehensive range of diagnostics and treatment for cardiovascular diseases, including heart attacks, heart failure (inadequate performance of the heart) and cardiac arrhythmia.

Our main areas of work in cardiology include non-invasive cardiology and pacemaker implantations.

  • Cardiological consultation
  • Resting electrocardiogram (ECG)
  • Holter ECG (one to seven days)
  • Cycle ergometry
  • Cycle spiroergometry
  • 24-hour blood pressure measurement

Clarity for your heart

We use specialised examinations such as the electrocardiogram (cardiac current curve) or cardiac ultrasound (echocardiography) to clarify your heart function.
