Long-term ECG monitoring.

ECG recording represents an essential method for the diagnosis of heart rhythm disturbances. Long-term monitoring helps to identify arrhythmias that have not been detected by means of standard 12-lead ECG or 24-48 hour ECG Holter. With time, ECG monitoring facilities improve, the ECG recorders are becoming smaller, and the recording time is prolonging. At present, continuous ECG recording is generally available. Smart watches and fitness bracelets further expand monitoring options in patients with known or suspected arrhythmia. Individual type and frequency of symptoms remain the most significant criterion for the selection of suitable ECG recorder and recording time.
