Cohort for study section Questionnaire: 1000 evaluable questionnaires are targeted. Every suitable potential respondent will be invited and interviewed during the data collection period. After 400 subjects in the questionnaire section, an interim evaluation will be carried out. Cohort for study section extended high-resolution ECG: In a feasibility study, signal-enhanced ECGs will be recorded in a subgroup of cohort before, during and after ablation with the aim of non-invasive ECG diagnostics. There are no published empirical values for this and 250 subjects will be notified. After 100 subjects in the high-resolution ECG section, an interim evaluation will be carried out.
