| 摘要 |
A catheter for the ablation of biological, in particular of animal or human, tissue, preferably for the ablation of human myocardial tissue, has at least one ablation or mapping electrode to permit the recording of ECG signals during catheter ablation and, in particular, to improve the quality of the recorded ECG signals to such an extent as to permit medical statements with reference to cardiac action. The at least one ablation or mapping electrode has a reduced number of electrical interference centers. Furthermore, the invention provides methods and apparatuses with the aid of which conventional catheters can be treated in such a way that these interference centers are reduced.
