HolterECG is a special procedure of monitoring heart activity for 24 hours. The patient comes to a telemedicine access centre with a “red” medical referral form of the Croatian Health Insurance Fund and a specialist’s recommendation for HolterECG. The referring professional collects all the necessary information from the patient. The small device is placed around the patient’s waist, and the electrodes are attached to the chest. The patient leaves and continues with his ordinary activities.

While wearing the HolterECG monitor during 24 (or 48) hours, the patient continues with his normal daily activities (work, physical activity, sleeping, taking medications) and habits (smoking, coffee consumption). It is even recommended to patients to be exposed to stressful situations in order to register potential arrhythmias occurring in such situations. 

According to the instructions of the referring professional, the patient keeps a short diary (“Patient’s diary”) about his activity in the course of the day. It is important that the patient keeps a diary of his activity during the HolterECG monitoring in order to establish a cause-and-effect connection between the symptoms and activities. There is a special button for the patient to press if he feels any type of discomfort.

The device records 3 selected ECG channels, usually V1,V3,V5. The ECG recording is uploaded to a computer via a memory card and sent to a teleconsultant. The teleconsultant is informed of the received HolterECG recording and the following functions are then analysed: mean heart frequency, ST segment depression, arrhythmias, pauses, Qtc interval and variability of heart frequency as an independent diagnostic indicator. This way, an objective insight is obtained into the condition of the heart muscle and its functioning, which is then used in further examinations or treatment.

The specialist’s (teleconsultant’s) report and opinion are available to the service recipient 72 hours (3 working days) after the HolterECG monitor was taken off in the premises of the telemedicine access centre.
