Radiofrequency versus Cryoballoon Ablation of Atrial Fibrillation: An Evaluation Using ECG, Holter Monitoring, and Implantable Loop Recorders to Monitor Absolute and Clinical Effectiveness

Figure 4

Kaplan-Meier estimates showing the cumulative freedom from all recurrent atrial arrhythmias after the radiofrequency ablation and cryoballoon pulmonary vein isolation. The average period of the recurrent arrhythmia development in the RFC group was 337,,6 days (95% CI: 316,5–357,9) and 307,8 (95% CI: 280,6–335,0) in the cryoballoon group. Freedom from all recurrent atrial arrhythmias did not differ between the 2 groups when compared by Mantel-Cox log-rank testing ().
