Beskrivelse
Inclusion Criteria:
- Subject is >18 years old
- Subject is referred for permanent pacemaker implantation with an indication for an atrial lead
- Subject has either paroxysmal atrial fibrillation or baseline intra-atrial conduction delay (P-wave duration >120ms on a 12-lead ECG)
- Subject is expected to remain available for standard-of-care pacemaker follow-up visits and study questionnaires
Exclusion Criteria:
- Subject has permanent atrial fibrillation or is in atrial fibrillation in the pre-operative area prior to the procedure (inability to assess paced P-wave morphology)
- Subject has pacemaker implantation prior to planned atrioventricular nodal ablation
- Subject has resting spontaneous sinus rate >85 beats-per-minute
- Subject has left ventricular ejection fraction <45%
- Subject is unable or unwilling to complete baseline or follow up quality of life questionnaires
- Subject is currently enrolled in a potentially confounding trial
- Subject is pregnant
- Subject's anticipated life expectancy is less than 1 year

Atrial Fibrillation Severity Scale Version 2.0
Tidsramme: Over 15 month follow up
|
Change in quality of life. The Atrial Fibrillation Severity Scale (AFSS) is composed of 19 items investigating four domains:

|
EQ-5D-3L survey (*EQ-5D-3L is the name of the instrument and is not an acronym)
Tidsramme: Over 15 month follow up
|
Change in quality of life.
The EQ-5D-3L is a standardized instrument to assess generic health-related quality of life and contains questions on five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression.
For each of the five dimension, respondents are offered three response categories (no problems, some problems, extreme problems), leading to 243 possible health states.
These health states are then converted into index based values (utilities) ranging from 0 to 1 by applying a valuation algorithm.
The EQ-5D instrument includes a visual analogue scale (VAS), on which the patient is asked to score his/her current health state between 0 (worst imaginable health state) and 100 (best imaginable health state).
