- Primary Outcome Measures
Name Time Method Correlation between speckle tracking determined global strain measurement and percentage of low voltage points in the left atrium.
- Secondary Outcome Measures
Name Time Method -Recurrence of atrial fibrillation within 12 months after a blanking period of 3 months defined as registration of atrial fibrillation on ECG or episode lasting >30 seconds on Holter/Vitaphone recording. <br /><br>-Correlation between strain/strain rate measurements and regional percentage of low voltage in the LA.; <br /><br>-Correlation between laboratory values and voltage measurements <br /><br>-Predictive value of strain/strain rate measurements and low voltage percentage for recurrent atrial fibrillation after catheter ablation. <br /><br>-Quality of life before and after PVI measured with SF-12 questionnaire<br>
