Filters for the detection of ECG esophagus. Rostock Filter is used with all models of esophagus electrodes Esosoft, Esoflex, Esokid and Esogold. The filtration highlights Pvågen and stabilizes the baseline. Connected to standard ECG devices and monitoring equipment. Variable gain. High-pass filter with quick selection of eight discrete frequencies.


The bipolar signal recorded and filtered in the Rostock Filter is displayed on the ECG apparatus or on the Monitoring Equipment on one of the precordial wiring channels, usually V1. Other connections for surface ECG registration are unchanged and connected just as usual. Only the selected precordial channel is used to display the signal from the esophagus. The signal shown is purely a bipolar recording of the ECG signal from the esophagus, not combined with any other signal from the surface ECG.
