Ablation of atrioventricular reentrant tachycardia (AVRT)

The picture shows catheter positions for ablation of left sided accessory pathways by the retrograde approach in the left anterior oblique (LAO) view. The ablation catheter is passed into the left ventricle through the femoral artery and the aorta. Surface ECG electrodes are marked by yellow arrows. The decapolar catheter is positioned in the coronary sinus and the quadripolar catheter is positioned in the region of the His bundle.
