Cardisiography · Cardisio
The heart's electrical activity
seen in three dimensions.
Cardisiography is a further development of vectorcardiography. Five electrodes record your heart's electrical signals in three dimensions at rest, and a trained algorithm analyses them. We use the method as a complement to ECG and echocardiography.
Why we take a closer look
More than a curve
on paper.
A resting ECG shows the heart's electrical excitation as curves from individual leads. In circulatory disorders of the coronary arteries, however, it is often normal at rest.
Cardisiography looks at the same excitation as a movement in space. An algorithm trained on measurements from people with known coronary findings searches it for patterns that may indicate a circulatory disorder or a change in the heart muscle. We always interpret the result together with your other findings.
How we proceed
Four steps.
One personal overall picture.
- 01
Personal consultation
We talk about symptoms, previous illnesses and risk factors and clarify which question the examination should answer.
- 02
Measurement at rest
Five electrodes are attached to the chest and back. The recording takes only a few minutes, with no exertion, no radiation and no contrast agent.
- 03
Algorithmic analysis
The measurement data are analysed using the manufacturer's system. The report is usually available shortly after the measurement.
- 04
Medical interpretation
We discuss the result together with your ECG, echocardiography and risk factors. If anything is abnormal, we plan further diagnostics in a targeted way.
Your questions about cardisiography
Clearly explained.
How does cardisiography differ from an ECG?
An ECG shows the electrical excitation as curves from individual leads and is assessed by a doctor according to fixed criteria. Cardisiography records the excitation spatially and analyses it with an algorithm. It does not replace the ECG but complements it.
Is the examination stressful?
No. The measurement takes place at rest, and the electrodes are attached as for an ECG. There is no radiation, no contrast agent and no physical exertion.
What is the method suitable for?
Cardisiography is intended to provide indications of circulatory disorders of the coronary arteries and changes in the heart muscle. We use it mainly in preventive care and for unclear symptoms as an additional building block.
Does a normal result rule out coronary heart disease?
No. No single method can rule out coronary heart disease with certainty. A normal result is a reassuring building block but does not replace the investigation of symptoms. If you have persistent chest pain, shortness of breath or circulatory problems, please call 112 immediately.
What happens if the result is abnormal?
An abnormal finding is not a diagnosis. We discuss it with you and, if necessary, plan further examinations, for example a stress echocardiogram, a coronary CT or myocardial scintigraphy with our radiology partner in the Medical Center.
Is cardisiography included in my check-up?
Yes, it is part of our private Essential and Professional check-ups. We will clarify with you in advance whether it is useful for you beyond that and how it is billed.
Scientific background
A young method.
Honestly assessed.
Cardisiography has been studied for several years. Depending on the comparison method, the results differ. That is why we use it as a complement and interpret every result medically.
