Abstract ObjectiveTo discuss the the feasibility,safety and advantages of Carto3 three-dimensional mapping system in guiding radiofrequency ablation for paroxysmal supraventricular tachycardia under low-dose radiation.MethodsA total of 65 patients with paroxysmal supraventricular tachycardia(PSVT)treated in our hospital from February 2015 to November 2017 were selected as the subject,and randomly divided into 2D group　(29 cases)and 3D group　(36 case).The 2D group used conventional X—Ray guide ablation,and the 3D group used Carto3 under low-dose radiation guide ablation.The PSVT type,operation time,X-ray exposure time,X-ray fluoroscopy time and complication rates were compared between the two groups.ResultsAll procedures were actely successful,but one patient in the 2D group was developed transient degreeⅢatrioventricular block during ablation.There was no statistically significant difference in the total operation time between the two groups(P＞0.05).The X-ray exposure time in 3D group was shorter than 2D group,and X-ray fluoroscopy time in 3D group were less than 2D group,the differences were statistically significant(P＜0.05).ConclusionRadiofrequency ablation of paroxysmal supraventricular tachycardia with the help of the Carto3 three-dimensional mapping system under low-dose radiation is safe and feasible，and is helpful to reduce the radiation injury of the doctors and patients.
