Specialists for your heart

The Cardiology Clinic at the Albertinen Hospital offers a full spectrum of invasive and conservative diagnosis and therapy, follow-up, and rehabilitation.

This coordinated and integrated treatment provides healthcare from a single source. The fully equipped cardiology area is supervised by a specialized team of physicians and nurses, and is equipped with ECG, ergometer, spiroergometry, lung function test, 3D echocardiography, two cardiac catheter places, pacemaker outpatient clinic, and heart MRI. A dedicated team of physicians and nurses is also available for therapy on the wards. In addition, all wards are equipped with mobile cardiac monitoring so that every patient can be well cared for.

The aim of our dedicated team of physicians, nurses, and medical and technical assistants is to offer everyone an individual, modern diagnosis and therapy for cardiovascular disease. Around 4,000 operations are performed each year.
