title: [Comparison of 24-hour electrograms taken simultaneously from the chest surface and from the esophagus by the Holter method].
abstract: The aim of work was to try to use a new technic of 24 hour Holter ECG, recorded simultaneously from the chest surface and supraventricular in order to differentiate between ventricular and supraventricular origin of heart arrhythmia. We investigated 20 patients but analysed 18 (in two cases we failed to obtained transesophageal ECG). The presence and time RP' of retrograde atrial depolarization during extrasystoles was analysed, usually hidden on chest surface ECG. In three cases we changed the diagnosis after analysis of transesophageal ECG. We did not observe any complications of prolonged transesophageal ECG recording.
