Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Correlation between speckle tracking determined global strain measurement and percentage of low voltage points in the left atrium. | — |
Secondary
| Measure | Time frame |
|---|---|
| -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. -Correlation between strain/strain rate measurements and regional percentage of low voltage in the LA.; -Correlation between laboratory values and voltage measurements -Predictive value of strain/strain rate measurements and low voltage percentage for recurrent atrial fibrillation after catheter ablation. -Quality of life before and after PVI measured with SF-12 questionnaire | — |
