AB  - INTRODUCTION: Supraventricular and ventricular tachycardias are common and 
      serious postoperative complications early after cardiac surgery. We introduce a 
      new temporary adjustable defibrillation electrode (TADE) for internal low-energy 
      cardioversion/defibrillation of postoperative atrial and ventricular 
      tachyarrhythmias. METHODS: Evaluation of the new electrode was performed in ten 
      open-chest beagles with a mean weight of 25.5 kg. The electrodes were first 
      positioned on the left and right atrium. Atrial fibrillation (AU) was induced via 
      a bipolar temporary heart wire. Atrial defibrillation thresholds (DFT's) were 
      measured according to a step-down shock protocol (5 J-0.4 J). Thereafter, the 
      electrodes were adjusted and positioned on the right and left ventricle. 
      Ventricular fibrillation (VF) was induced and DFT's were recorded the same way. 
      RESULTS: For termination of AF, mean DFT's were 0.4 +/- 0 J (lowest possible 
      shock level) with a mean shock impedance of 70 +/- 7.6 omega. VF was terminated 
      with a mean DFT of 3 +/- 1.1 J with a mean impedance 56.1 +/- 7.9 omega. Complete 
      transcutaneous removal of the electrodes was possible in all animals without any 
      complications. CONCLUSION: Successful low-energy termination of AF and VF is 
      possible with the tested temporary adjustable electrode. A clinical study is 
      planned for further evaluation.
