Non-invasive cardiology deals with all diagnostic clarifications and therapeutic measures for heart diseases that can be carried out externally without penetrating the body. Particular focus is placed on imaging examinations such as heart ultrasound (echocardiography) as well as magnetic resonance imaging (MRI) and computed tomography (CT) of the heart. Another important non-invasive diagnostic test is the electrocardiogram (ECG), which allows the electrical activity of the heart to be recorded. In a stress test (ergometry), the ECG is performed under physical stress (bicycle test).

These examinations are used to diagnose heart-related illnesses such as angina pectoris, cardiac insufficiency (heart failure), heart attack or heart valve defects. For further clarification and treatment of these diseases, non-invasive cardiology works closely with other sub-disciplines of cardiology such as invasive cardiology, rhythmology or outpatient cardiac rehabilitation.
