[New trends in ECG Holter monitoring].

The authors review contemporary possibilities of Holter ECG monitoring. In the first group of patients they emphasize possibilities and the yield of long-term ambulatory ECG monitoring by means of an apparatus started by the patient. The second group of patients was examined by Holter monitoring, using an oesophageal lead. It is a method hitherto not used in the Czech Republic, which if properly indicated, improves the non-invasive diagnosis of cardiac arrhythmias.
