Elektrokardiografie (EKG)

Electrocardiography (ECG)

The standard repertoire of cardiopraxis includes all procedures of electrocardiography – ECG for short. The ECG represents the electrical processes in your heart in the form of curves, either on the screen or printed on paper. To do this, electrodes are applied to various parts of the body to record and analyze the pattern of your heartbeat.

This provides our cardiologist with valuable information on possible heart diseases, ranging from cardiac arrhythmias to heart muscle inflammations and heart attacks.

We carry out the rest ECG while you are lying down, with your upper body free. Depending on which question we want to pursue in Cardiopraxis, there are two further procedures in addition to the usual resting ECG. If we want to find out whether your heart problems only occur during physical exertion, we use the exercise ECG, also known as ergometry. If we want to track down irregular heart rhythm disturbances, the long-term ECG is the right procedure.

All three ECG methods work in the same way, but the procedure is slightly different.

Resting ECG

How does it work with us?

The resting ECG is part of the basic diagnosis in Cardiopraxis. It goes without saying that we offer this important examination to every patient in order to obtain valuable information about their heart health in a simple and compact way. This allows us to attach a total of 12 electrodes to the ECG device at various points on your chest and on your arms and legs – all of this is absolutely painless. The subsequent electrocardiographic recording takes just one minute.

When do we do it?

With the Ruhe-EKG we can find answers to many questions: Does your heart beat too fast, too slowly or irregularly? Is the excitation formation in the heart or the conduction disturbed? Was there a heart attack? What is the load on the atria and main ventricles? And if you have a pacemaker: Are there any disturbances here? It can also be used to monitor the effect of drugs – not only cardiovascular drugs, by the way, but also psychiatric drugs, for example.
The resting ECG is quite a simple procedure. However, an experienced cardiologist can read a lot about it – as in our cardiopraxis: We carry out more than 10,000 resting ECGs per year!

Stress ECG (ergometry)

How does it work with us?

The procedure for a stress ECG is somewhat different. To see how your heart reacts to exertion, ride a bike with your upper body free – the ergometer. Therefore, please bring comfortable clothing to the examination! Before you pedal, you will be connected to the ECG measuring device via 10 electrodes. Every 2 minutes the examining doctor increases the load by 25 watts up to the so-called “target heart rate”. This depends on your individual requirements, such as age and weight. In addition to ECG recording, your blood pressure and pulse are also measured. The exercise ECG lasts about 15 minutes in total.

When do we do it?

We perform a stress ECG primarily for symptoms such as chest tightness (angina pectoris), shortness of breath during stress and other stress related symptoms, but also as follow-up care for coronary heart disease or as part of screenings. With the results, we can see, for example, whether you suffer from cardiac arrhythmia during exertion, how your pulse and blood pressure are during exertion, or whether your heart suffers from circulatory disorders.

At both Cardiopraxis locations we have several measuring stations. Every year we perform about 3,500 exercise ECGs.

Long-term ECG

How does it work with us?

Cardiac arrhythmias, which occur irregularly, may remain undetected in the relatively short resting ECG. The long-term ECG provides a solution: over a period of at least 24 hours (and in individual cases up to 7 days), this device continuously records your electrical cardiac activity. Cardiopraxis offers its patients particularly small and lightweight ECG devices that can be worn comfortably in everyday life and measure with only three electrodes. After an easy-to-understand introduction to the use of the device, our patients usually receive a long-term ECG in the morning in our practice. In a one-page documentation sheet, they must also note what activities they are doing during the measurement period. The next morning at 8 a.m. we receive the device again in order to then evaluate the measurement data on the computer.

When do we do it?

We mainly use the long-term ECG to identify temporary cardiac arrhythmia or cardiac insufficiency. The method is also suitable for risk analysis after a heart attack. In total, we carry out around 1,500 examinations per year per long-term ECG in Cardiopraxis.

Determination of Heart Rate Variability with HRV Scanners

A healthy heart constantly changes its beat rate, even if only in the millisecond range – with a conventional ECG-device we cannot detect this. The change of the time intervals between two heartbeats, the so-called heart rate variability (HRV), can still be measured.

With the highly sensitive HRV scanner from BioSign and data from long-term ECG measurements, we can determine your personal heart rate variability precisely and conveniently in Cardiopraxis, so that we can then initiate therapies if necessary. Because if the HRV is too low, diseases such as high blood pressure, cardiac arrhythmia or heart failure can be the result.

How does the examination with the HRV scanner work with us?

The examination with the HRV scanner takes place while lying down in a quiet environment and takes about 5 minutes. Two electrodes are attached to your left and right wrist and connected to the HRV scanner. On a monitor, our cardiologist is finally shown a simple and transparent display of various parameters that determine your personal HRV.

When do we do the HRV scan?

The HRV scan is used for symptoms such as restlessness, high blood pressure or heart failure. Results from this examination may indicate, for example, that your vegetative nervous system is out of balance. This is usually due to excessive stress. Therapies individually adapted to your situation to normalize the HRV range from certain breathing techniques to physical training, weight reduction and biofeedback.

In the two Cardiopraxis branches, our team of doctors carries out around 1,500 HRV examinations annually.


As one of only a few cardiological practices in Germany, we also offer our patients cardiogoniometry – a state-of-the-art electrocardiographic procedure that has only been available for a few years.

Like the conventional rest ECG, it measures the electrical activity of your heart. However, fewer electrodes are required for the examination and the representation of the heart activity is three-dimensional – and thus much more accurate than with the rest ECG.

How does cardiogoniometry work with us?

In the resting position, the patient first applies five electrodes to the chest at a clearly defined distance. The actual measurement takes only 12 seconds! Special software then evaluates the data and creates a three-dimensional image of your heart on the monitor. The cardiologist receives valuable information about irregularities in the propagation and regression of excitation in your heart from the “electrical map”. This is because even in the early stages of heart diseases, the electrical system can be disturbed – for example, in the event of an imminent heart attack. The entire examination takes a maximum of 10 minutes. One advantage is that cardiogoniometry is performed at rest and can therefore also be available to people with limited mobility or elderly people.

When do we perform cardiogoniometry?

The medical team of the Cardiopraxis uses the Cardiogoniometry mainly for symptoms like chest tightness (angina pectoris) or shortness of breath during stress. The procedure helps in particular to uncover circulatory disorders of the heart. Often further diagnostic steps are initiated afterwards.

Every year we perform the innovative method cardiogoniometry about 500 times.
