Services & Diagnostics
We combine modern high-end diagnostics with personal care – to assess your heart, circulation and lung function with precision and to develop treatment plans tailored to you.
Vectorcardiography – for earlier and more accurate detection of heart disease.
Cardiac ultrasound (echocardiography) – to visualize heart structure and function in detail.
Stress echocardiography – to see how your heart performs under physical strain.
Carotid ultrasound (Doppler / duplex) – to assess blood flow and detect vascular risks early.
Pulmonary function testing (spirometry) – to measure lung capacity and breathing strength.
Sleep apnea screening (polygraphy) – to uncover causes of snoring, fatigue or poor sleep.
Pacemaker, defibrillator and CRT follow-up checks – for safe and reliable device monitoring.
Cardiac Computed Tomography (Cardio-CT)
Symptoms
Chest Pain
Chest pain is always a serious warning sign and should never be ignored. In our clinic, we can quickly determine whether your heart is affected and initiate the right treatment. With us, you are in safe and experienced hands.
Shortness of Breath
Sudden or increasing shortness of breath can indicate heart or lung disease. These symptoms require careful evaluation. We provide thorough diagnostics to identify the cause and ensure you receive the right therapy.
Heart Rhythm Disturbances
An irregular heartbeat, palpitations, or skipped beats may feel unsettling and can signal a relevant rhythm disorder. With state-of-the-art diagnostic tools, we assess your individual risk and help you regain security in your daily life.
High Blood Pressure
Persistently high blood pressure silently damages the heart and blood vessels. Early diagnosis and consistent treatment are essential. We help you bring your blood pressure under control and prevent long-term complications.
Dizziness
Dizziness may be linked to heart rhythm issues, circulatory problems, or neurological conditions. We take your symptoms seriously and carefully investigate whether your heart is involved, giving you clarity and the right treatment.
Loss of Consciousness
A fainting episode or sudden loss of consciousness should always be taken seriously, as it may point to heart or circulatory problems. In our clinic, we identify the cause and protect you from potential risks.
Daytime Fatigue
Persistent daytime fatigue can be a sign of sleep disorders such as sleep apnea, which may place significant strain on the heart and circulation if left untreated. We offer modern diagnostics to detect the cause and restore your energy and quality of life.
Insomnia
Chronic difficulty sleeping affects overall health and the cardiovascular system. We investigate the causes of your sleep problems and work with you to find solutions that safeguard both your health and your well-being.
Decline in Performance
A sudden loss of stamina or physical strength should always be taken seriously. In many cases, it may be linked to an undetected heart condition. With targeted examinations, we help you identify the cause early and guide you back to full performance.
Snoring
Loud, regular snoring is not only bothersome but can also signal sleep apnea – a serious condition that raises the risk of high blood pressure, heart attack, and stroke. With modern and simple diagnostic methods, we can detect risks early and protect your health.
