  Einrichtung zur Aufnahme von Elektrokardiogrammen durch Ableitung der Spannungen aus der Speiseröhre 
 EMI1.1 
 der Oesophagus-Elektrode kardiographisch die Veränderungen der Herzstromkurve nach Arbeit oder nach Einwirkung von Pharmaka untersucht werden sollen, da diese Veränderungen im allgemeinen sehr rasch ablaufen und daher schnelle Registrierung erfordern. 



   In der Zeichnung ist ein Ausführungsbeispiel der   erfindungsgemässen   Elektrode dargestellt. 



   Der in die Speiseröhre einzuführende Teil besteht aus einem dünnen Schlauch 1 aus Isolermaterial, z. B. Gummi, dessen Ende mit einem abgerundeten metallischen Verschluss 2 versehen ist. Ausserdem sind in Abständen von je etwa 2 cm zehn metallische Ringe 3 aufgesetzt und jeder dieser Metallkörper ist durch einen isolierten, im Inneren des Schlauches verlaufenden Draht an einen der festen Kontakte des Wahlschalter 4 angeschlossen. Dabei kann zwischen dem dünnen Schlauchteil und dem Schalter noch ein etwas dickerer, nur der Verlängerung dienender Schlauch 5 eingesetzt sein. Mit Hilfe des drehbaren Knopfes 6 kann nun jede beliebige der Ableitungen 3 an die Steckbuchse 7 geschaltet werden, an die der Elektrokardiograph angesteckt wird.

  Device for recording electrocardiograms by deriving the voltages from the esophagus
 EMI1.1
 the esophageal electrode should be examined cardiographically, the changes in the cardiac current curve after work or after exposure to pharmaceuticals, since these changes generally take place very quickly and therefore require rapid registration.



   An exemplary embodiment of the electrode according to the invention is shown in the drawing.



   The part to be inserted into the esophagus consists of a thin tube 1 made of insulating material, e.g. B. rubber, the end of which is provided with a rounded metallic closure 2. In addition, ten metallic rings 3 are placed at intervals of about 2 cm each and each of these metal bodies is connected to one of the fixed contacts of the selector switch 4 by an insulated wire running inside the hose. A somewhat thicker tube 5, which is only used for extension, can be inserted between the thin tube part and the switch. With the help of the rotatable knob 6, any of the leads 3 can now be connected to the socket 7 to which the electrocardiograph is plugged.
