Exploring P-Wave Duration in Arrhythmia Recurrence in Patients Undergoing AF Ablation

NCT04968678 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 100

Last updated 2021-07-20

No results posted yet for this study

Summary

The aim of this study is to investigate whether P-wave duration in a baseline surface 12-lead ECGs correlates with recurrence of AF recurrence post successful ablation at the time of the procedure.

Conditions

  • Atrial Fibrillation Recurrent

Interventions

DIAGNOSTIC_TEST

P-wave duration measurement on 12 lead ECG with standard parameters

Hospital records will be used in order to obtain baseline characteristics and the most recent 12-lead ECG in sinus rhythm prior to ablation will be used to calculate PWD. Measurement of the PWD will be obtained at standard surface ECG recording settings of 25mm/s and 10mm/mV and measured accordingly to our previous protocol. In brief, all ECGs obtained will subsequently be anonymised and randomised by an Independent Clinical Investigator (ICI) before measured by the main clinical investigators blinded to initial results. If a dispute of the measurements arouse, consensus will be used to resolve it after consulting the Chief Investigator (CI) blinded to the results. Bland-Altman plots to minimise bias will be used
