Event-Recorder - implantations and checks

What is an Event Recorder?

An event recorder is a small device containing a memory chip, which can record occasionally occurring heart rhythm disorders. In contrast to the long-term ECG, the ECG recording is initiated by the patient as soon as the complaints occur. After recording of one or several complaint episodes, the data is evaluated in the practice.

When is an Event Recorder necessary?

An event recorder is used primarily for the diagnosis of heart rhythm disorders which only occur occasionally. It is however also possible to find indications of temporary circulatory disorders.


There are two different types of event recorders: portable and implantable event recorders.

Implantable devices are coming into increasing use, and are inserted under the skin under local anaesthetic. The procedure takes about five minutes, and is carried out in the operating theatre of the HPK.

This is different in the case of a portable event recorder. The recorder is lent to the patient for several weeks, and should be carried at all times during this period. If a heart rhythm disorder occurs, the patient places the device on his chest and presses a button. The recorder records the episode, and the data can then be read into the computer and evaluated in our private clinic.


Recording by means of the portable event recorder involves practically no risks for the patient.

When using an implantable event recorder, the risks of the intervention must be considered. This may result in allergies, medication intolerance and infections at the incision. Pressure points may also occur because of the device.
