Outcome Measures

Primary Outcomes (1)

  • Change in AF burden

    Defined as % of time in AF, during screening period compared to end of treatment period.

    14 weeks

Secondary Outcomes (11)

  • AF burden defined as the total number of AF events during screening period compared to end of treatment period.

    14 weeks

  • AF burden defined as the total number of symptomatic AF events during screening period compared to end of treatment period

    14 weeks

  • Change from baseline compared to end of treatment period in Life quality & symptoms as assessed by AF AFEQT(from 0-poor to 100-great), EHRA Score (from I-no symptoms to IV-disabling symptoms) and SF36 questionnaires (form 0-worst to 100-best)

    14 weeks

  • Number of AF episodes lasting 6 hours or longer in the treatment arm compared to the sham control

    14 weeks

  • Group change in acute reduction of PAC (number of PACs in 2 minute ECG) compared before and immediately after neuromodulation sessions

    14 weeks

  • +6 more secondary outcomes
