ABSTRACT
Objective:
To observe the relationship between heart rate on atrioventricular node reentrant tachycardia (AVNRT) sustaining and slow path position during procedure of slow path modified ablation using three-dimensional mapping system.Methods:
Modified ablation of slow pathway under three-dimensional mapping system was performed in 98 patients with slow-fast (S-F) AVNRT confirmed by invasive electrophysiology examination. The successful target (the site of slow-pathway) and standard His bundle were marked using three-dimensional mapping system, and the distance (Distance A) between the successful target and standard His bundle was measured. The relationship between heart rate in AVNRT and Distance A was analyzed.Results:
Distance A was successfully obtained in 96 patients, including 64 tachycardia induced without infusion of isoproterenol, the heart rate was (179.77±29.22)bpm and relevant Distance A was (13.56±5.06)mm, also 32 tachycardia induced with infusion of isoproterenol, the heart rate was (174.91±17.41)bpm and relevant Distance A was (12.43±3.70)mm. No obvious correlation between heart rate and slow path position was found among the above 96 patients (rs=0.048, -0.190; P=0.705, 0.298).Conclusion:
There was no obvious correlation between patient's heart rate on AVNRT sustaining and slow path position druing the procedure of slow path modified ablation using three-dimensional mapping system.
