The Holter ECG is a non-invasive diagnostic test that involves recording the heart’s electrical activity by means of a small portable device (recorder) connected to the skin via some electrical wires and electrode pads (small platelets) placed on the chest

What is the dynamic Holter ECG used for?

Analysis of the 24-hour recorded trace can detect a rhythm disturbance (arrhythmia) or insufficient blood supply to the heart (ischaemia).

Any symptoms reported by the patient during the recording period can be correlated with changes in the ECG.

Are there any preparation rules?

There are no preparation rules.

In male patients, in order to improve the adhesion of platelets to the skin, it may be necessary to remove chest hair.

The possible discontinuation of a treatment/drug is only determined by the physician requesting the test.

How does the dynamic Holter ECG work?

The Holter ECG is a portable device attached to the skin via a few wires and electrode pads placed on the chest.

The electrodes pick up the electrical activity produced by the heart and transmit it to the device, which records it in its memory.

In this way, the system can store all heartbeats generally for a period of 24 hours.

During the test, the patient can carry out daily activities without restriction, taking care only that the electrodes do not come off the skin (perhaps through excessive sweating) and interrupt the recording.

Once the device is removed, the stored electrical signal is processed by an external device and evaluated by the specialist.
