Long-term ECG: Procedure

If the doctor wants to apply the long-term ECG, he sticks six electrodes to the patient's chest and connects them to the ECG recorder. This is small and compact and can be easily attached to the belt or wear around the neck. The data is saved on a memory card. For the measurement, the patient can pursue his daily activities as usual. He should write down exactly what activities he pursues and whether he suffers complaints.

Long-term ECG: evaluation

The Holter is often evaluated computer-aided. Thus, changes in heart action can be revealed in no time. For the long-term ECG diagnosis, the electronic evaluation is usually carried out by an experienced doctor. It collects the lowest, middle, and highest heart rates, cardiac rhythm, and possibly ECG changes that indicate disease. The physician compares these values ​​with the symptoms described by the patient and assesses whether the heart's response is appropriate or pathological.
