Supraventricular Tachycardias Using Multiple Accessory Pathways

Figures

• 

  FIGURE 1. Twelve‐lead electrocardiograms before and after the ablation (ABL).

• 

  FIGURE 2. Fluoroscopic images exhibiting the catheter positions at baseline (left panels), and the successful ablation (ABL) sites at the posterior aspect of the tricuspid annulus (middle panels) and lateral aspect of the mitral annulus (right panels). CS, coronary sinus; HB, His bundle; LAO, left anterior oblique projection; RAO, right anterior oblique projection; RV, right ventricle; TA, tricuspid annulus.

• 

  FIGURE 3. (A) Activation maps recorded during sinus rhythm (left panel) and RV pacing (right panel) at baseline. (B) Activation maps and cardiac tracings recorded during supraventricular tachycardia (SVT)1. (C) Activation map and cardiac tracings recorded during SVT2. (D) Activation map and cardiac tracings recorded during SVT3. The yellow and white arrows indicate the reentrant circuits of the SVTs and locations of the accessory pathways, respectively. The yellow and white arrowheads indicate the ventricular and atrial potentials, respectively. IVC, inferior vena cava; LA, left atrium; LV, left ventricle; RA, right atrium; SVC, superior vena cava; X 1 to 10 = the first to tenth electrode pairs of the relevant catheter. The other abbreviations are as in the previous figures.
