Non-invasive Differentiation of Supraventricular Tachyarrhythmia

Summary

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

Inclusion Criteria:

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

Exclusion Criteria:

* Unstable patient with need for intensive medical care
* Lack of language skills or limited cognitive abilities that prevent a differentiated anamnesis and information.

Exclusion criteria for study section Questionnaire:

\- Competing clinically present arrhythmias, including relevant supra- and ventricular extrasystole (\>5%/die).

Exclusion criteria for study section Extended high-resolution ECG:

* Previous electrophysiological ablation at the same site for atrial fibrillation.
* Relevant supra- and ventricular extrasystole (\>5%/die).
* Other clinically present arrhythmias are not excluded if they can be sequentially triggered and ablated (e.g. atrial fibrillation and atrial flutter). Since separate detection is possible with the high-resolution ECG.
* Implanted active electrical device (e.g. pacemaker, defibrillator, deep brain pacemaker)
* Allergy to measuring electrodes
