BACKGROUND
Background: Radiofrequency ablation has obvious advantages in the treatment of arrhythmia, like few postoperative complications, high cure rate, low recurrence rate, and small trauma, which has become the first choice for patients to treat arrhythmia.
OBJECTIVE
Objective: To study the X-ray dose of radiofrequency ablation in patients with paroxysmal supraventricular tachycardia (PSVT), ventricular premature beat and ventricular tachycardia (PVC/VT) arrhythmia based on CartoUnivu and Carto3 intelligent system.
METHODS
Methods: Radiofrequency ablation based on CartoUnivu and Carto3 system was used to treat patients with PSVT, PVC/VT arrhythmia, and the X-ray dose of thyroid, perineum, left upper arm, intrathyroid, extrathyroid, intrathoracic, extrathoracic, intraperineum, extraperineum and other parts during the treatment was analyzed.
RESULTS
Results: In most PSVT patients, radiofrequency ablation guided by Carto-3 system had lower X-ray dose than that of CartoUnivu. Radiofrequency ablation under the guidance of CartoUnivu was better than that of Carto3 regarding the X-ray level of most PVC/VT patients. Radiofrequency ablation under the guidance of CartoUnivu system had lower X-ray radiation for PVC/VT patients.
CONCLUSIONS
Conclusions: CartoUnivu system and Carto3 system can guide the precise treatment of complex arrhythmia, have a high success rate and better safety, can significantly reduce the X-ray exposure time and dose received by patients and operators, and the risk of X-ray related damage is significantly reduced, which is worth promoting.
