[Holter ECG monitoring during gastroscopy in patients with chronic atrial fibrillation].

The authors present their results obtained with Holter ECG monitoring during gastroscopy in a group of patients with chronic atrial fibrillation. In one third of the group, endoscopic procedure induced complex cardiac arrhythmias and also significant myocardial ischaemia. These findings can have serious hemodynamic consequences. Therefore previous evaluation of cardiac findings and extemporaneous for urgent therapeutical intervention are necessary. To these patients, especially to those with cardiac arrhythmias--including atrial fibrillation--it is necessary to devote intensified attention and precaution with interdisciplinary co-operation.
