Correction to: The effect of second-generation cryoablation without electrical mapping in persistent AF using continuous monitoring.

Figure 1 as originally published is incorrect. On the published Fig. 1 it reads 3 patients Medtronic Sensia and 3 patients Medtronic Advisa. This should read 1 patient Medtronic Sensia and 1 patient Medtronic Advisa. Figure 1 has been corrected below.
