Figure 4.
Placement of basket catheter into trauma-induced (stab wound to chest with cardiac perforation) left ventricular apical aneurysm reveals diastolic activation from spline H1-4 (early diastolic) to G1-4 (presystolic). VT was terminated by ablation between these two splines. After termination, sinus rhythm LP activation proceeds from G1-4 to H1-4. A single RF application using retrograde approach magnetic navigation targeted at the earliest LP at G1-4 delays and eliminates H 1-4, which is 15 mm away.
