Abstract

Abstract:

Objective

To compare the difference of the time of the radiofrequency catheter ablation of atrioventricular nodal reentry tachycardia with the three-dimensional (3D) and two-dimensional (2D) mapping.

Methods

From January 2014 to April 2015 the paroxysmal room on the first hospital of Shanxi Medical University underwent radiofrequency ablation of tachycardia in 65 cases of patients with radiofrequency ablation rate, the measurement methods are divided into two groups (32 cases) and group D (33 cases). The operation time, X-ray fluoroscopy time, immediate ablation success rate, recurrence rate and complications were compared between the two groups.

Results

There are no significant difference in operation time, surgical success rate and complications in both groups , fluoroscopy time of 3D group is significantly reduced, mainly to reduce the ablation catheter fluoroscopy time.

Conclusion

3D mapping can significantly reduce the X-ray irradiation time in radiofrequency ablation of AVNRT patients.
