Manifold benefits of choosing a minimally fluoroscopic catheter ablation approach

Figure 2 Three consolidation pulses were delivered at the same site. A: The effective radiofrequency (RF) pulse. Ventricular preexcitation disappeared 4 s after the pulse was started and, few beats later, a junctional rhythm with 1:1 retrograde conduction overtook sinus rhythm. Thus the RF pulse was prematurely stopped. As the phenomenon could be reliably reproduced, subsequent consolidation pulses were delivered during atrial pacing with the irrigated-tip ablation catheter up to a maximum of 15 W; B: A RF pulse delivered during atrial pacing with emergence of junctional rhythm as pacing was stopped; C: Transient complete atrioventricular block during adenosine injection at the end of the first ablation procedure.
