An event recorder is used in the event of a heart rhythm disorder and when it appears that a previous examination with a Holter (Holter examination) has not provided sufficient data. This recorder is worn for at least a week, sometimes even a month or longer if necessary. There are various event recorders such as a kind of wristwatch, an implantable recorder or a box. The data is often sent directly to the hospital via a mobile phone.
If someone has a heart rhythm disorder or if this is suspected, further investigation is required. A heart rhythm disorder does not necessarily have to be serious immediately, but it can have unpleasant consequences in the long term. A cardiac arrhythmia can ultimately even lead to a myocardial infarction. That is why it is important to investigate what exactly is going on. A heart rhythm disorder can be recognized by the patient by a beating heart in the throat, a fast or slow heartbeat, a fluttering heart, shortness of breath and/or shortness of breath.
Event recorder and holter examination
First of all, a Holter examination will take place. An ECG (ECG) is made over 24 to 48 hours. The patient wears a box with 4 to 7 electrodes that are taped to the chest. An exercise test (cycling test) and ultrasound are often required. The cardiac arrhythmia is not always registered during these 24 to 28 hours. This has to do with the fact that heart rhythm disorders can occur very irregularly and often occur at the most unexpected moments.
If this is the case, you can use an event recorder, also known as an event recorder. An event recorder records the heart rhythm over a longer period of time. This is often for a week or longer if necessary. There are several types of event recorders.
Box and electrodes
The most commonly used event recorder is a device (or event clip) that is also used for a Holter examination, but with a slightly different function. A box is connected to electrodes that are stuck to the chest. The breast is cleaned and gel is applied to the stickers. Sticking the electrodes on is painless, the wires are clicked onto the stickers. The box records the heart rhythm, but not continuously. Only when complaints occur can a button be pressed. The heart rhythm is recorded at that moment for fifteen minutes after, but also fifteen minutes before, the complaints. This allows you to look back in time. This is useful when people disappear for a while during complaints and only press the button later.
Another way is a type of watch worn on the left wrist. This device also records the heart rhythm at the time of complaints. No button needs to be pressed, but the other hand is placed on the watch. The device then starts recording.
There is also an implantable heart monitor. This is applied under local anesthesia. This is 6 cm long and 2 cm high and less than 1 cm thick. The device is implanted just under the skin of the breast. External cables are not necessary, this makes it easy. It registers abnormal heart rhythms fully automatically, but the patient can also use the remote control to register an arrhythmia. Removal of the device must also be done under local anesthesia.
Some of these event recorders can record up to 15 minutes, sometimes more. The cardiologist prefers to have the data sent directly via a mobile phone with Bluetooth. The data is sent directly to the hospital. The mobile phone provided to the patient must always be within range of the event recorder, otherwise it will not be possible to send the data. The cardiologist regularly reviews the data and will call the patient if there are any questions or observations.
Showering with an event recorder
The recorder is not waterproof. It is therefore necessary to disconnect the device and store it dry before showering. You can shower with the stickers on the chest. The recorder can then be connected again. If the stickers cause a lot of itching or are peeling off, they can be removed. The patient always receives sufficient new adhesives and instructions on how to place them properly. The event recorder always remains the property of the hospital and must therefore be returned. This research will be reimbursed from your basic insurance. However, the deductible is first addressed. A referral from a general practitioner or medical specialist is required for reimbursement.
