About this trial

1. Questionnaire for supraventricular tachycardia: About history and targeted diagnosis of supraventricular tachycardia 2. Extended Signal-averaged ECG for detailed P-Wave analysis and to calculate a virtual atrial electrocardiogram (ECG)

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Scheduled for ablation of a supraventricular tachycardia (atrial fibrillation, typical atrial flutter, AV nodal reentry tachycardia, accessory pathway)

majority

Disqualifiers

Unstable patient with need for intensive medical care

Lack of language skills or limited cognitive abilities that prevent a differentiated anamnesis and information.

Previous electrophysiological ablation at the same site for atrial fibrillation.

Relevant supra- and ventricular extrasystole (>5%/die).

Trial population

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.
