ABSTRACT
Objective:
To investigate the couse of 24 cases AVB during RFCA and 5 cases after RFCA in total 94 AVNRT patients.Methods:
94 AVNRT patients received RFCA in which time, the energy and power were gradually discussed. The correlation among AVB and both different anatomical positions (upper, middle and lower zone) and A/V, H-value in intraventricular ablation mapping were studied respectively.Results:
With the elevation of ablation zone, the AVB risk was also increased. The intraventricular ablation mapping showed that①Increase of A/V and H-value means higher AVB risk;② Simultaneous increase of A/V and H-value would lead to the most dangerous result.Conclusion:
It is of great importance to perform RFCA under such situationmiddle and lower zone as ablation positions multiple-peak A wave, A/V(0.1-0.25) and no H or slightest H(≤0.02?0.03)mV are present in intraventricular ablation mapping, which could significantly lower the risk of RFCA-related AVB.
