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
