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 medical-diagnostic services in the field of cardiology

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

  • Cardiological consultation
  • Electrocardiogram (ECG)
  • Long-term ECG (24 hours to 7 days)
  • Implantation and checks of loop recorders
  • Implantation, checks and replacement of pacemakers and ICDs
  • Outpatient electroconversion
  • Exercise ECG (bicycle ergometry, spiroergometry, physical stress echocardiography)
  • Transthoracic echocardiography (TTE), including advance technique (3D, strain, etc.) and contrast sonography
  • Transoesophageal echocardiography (TEE)
  • Drug-induced stress echocardiography (dobutamine)
  • Stress MRI of the heart
  • Computed tomography of the heart

Clarity for your heart

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