Oesophageal electrode probe and device for cardiological treatment and/or diagnosis

A device for transesophageal cardiological treatment and/or for transesophageal cardiological diagnosis, comprising:

• an esophageal electrode probe that includes a bioimpedance measuring device for measuring the bioimpedance of at least part of tissue surrounding the esophageal electrode probe, wherein the bioimpedance measuring device comprises at least one first electrode and at least one second electrode, wherein the at least one first electrode is arranged on a side of the esophageal electrode probe facing the heart, and wherein the at least one second electrode is arranged on a side of the esophageal electrode probe facing away from the heart;
• a control and/or evaluation device in signal connection with the bioimpedance measuring device, wherein the control and/or evaluation device is adapted to receive and compare a first bioimpedance measurement signal from the at least one first electrode and a second bioimpedance measurement signal from the at least one second electrode, and to generate a check signal on the basis of the comparison.

A method for controlling or regulating an ablation device for performing a cardiac catheter ablation and/or a cardiac, circulatory and/or respiratory support device for cardiosynchronous cardiac, circulatory and/or respiratory support, the method comprising:

• detecting a first bioimpedance measurement signal from at least one first electrode, wherein the at least one first electrode is arranged on a side of an esophageal electrode probe facing a heart;
• detecting a second bioimpedance measurement signal from at least one second electrode, wherein the at least one second electrode is arranged on a side of the esophageal electrode probe facing away from the heart;
• generating a control signal for controlling or regulating the ablation device and/or the cardiac, circulatory and/or lung support device on the basis of a comparison of the first bioimpedance measurement signal with the second bioimpedance measurement signal.
