Abstract
A transvenous catheter for the cardioversion of atrial fibrillation or atrial flutter and/or the stimulation of the heart'"'"'s activity. The catheter has an electrically active section within a heart and an electrically passive section carrying electrical cables. At least two defibrillation electrodes are located in the electrically active section and coupled to the electrical cables of the catheter. Additionally, there are at least one sensing ring electrode positioned between the at least two defibrillation electrodes and coupled to the electrical cables.
