NCT03816033

Brief Summary

A program of research has been set up at St. George's Hospital, London studyng the practicalities of catheter ablation. The current practice of catheter ablation is being studied for a range of arrhythmias including PAF, persistent AF, advanced persistent AF and resistant WPW.

Outcome Measures

Primary Outcomes (3)

  • Recurrence of the treated arrhythmia at 6 months

    Recurrence of the treated arrhythmia or related tachycardia will be recorded in a single timeframe of 6 months. The method for recording recurrence will be from Holter or via loop recorder download.

    6 months

  • Recurrence of the treated arrhythmia at 12 months

    Recurrence of the treated arrhythmia or related tachycardia will be recorded in a single timeframe of 12 months. The method for recording recurrence will be from Holter or via loop recorder download.

    12 months

  • Recurrence of the treated arrhythmia at 24 months

    Recurrence of the treated arrhythmia or related tachycardia will be recorded in a single timeframe of 24 months. The method for recording recurrence will be from Holter or via loop recorder download.

    24 months

Secondary Outcomes (2)

  • The rate of major adverse cerebrovascular and/or cardiovascular complications (defined as MI, CVA, vascular, oesophageal trauma, phrenic nerve injury) will be recorded

    24 months

  • To record the patient quality of life improvement by filling in a Short Form-36 questionnaire

    24 months
