Figure 1. Ablation catheters used in the study.
A) IntellaTip MiFi OI catheter equipped with three mini-electrodes (large arrow) and irrigation holes (small arrow) at distal tip. B) Blazer II HTD catheter.
Figure 2. Discrete pathway electrograms in ME catheters.
A) SP electrograms in MEs (small arrows), B) Right posteroseptal AP electrograms during ventricular pacing in distal ablation electrodes (large arrow) and MEs (small arrows), C) AP electrograms in MEs during preexcitation via left lateral AP (small arrows), D) Left lateral AP electrograms in MEs during AVRT (small arrows).
ME = mini electrode; SP = slow pathway; AP = accessory pathway; AVRT = atrioventricular reentrant tachycardia.
