Arrhythmias & electrophysiology
Patient-reported symptomatic events do not adequately reflect atrial arrhythmia
Authors' conclusion
Whereas AT/AF events increase the chances of symptoms, there is poor overall correlation between symptomatic events and documented AT/AF. Patient factors and prior treatments influence SRC.
Study context
- Population
- Patients with ambulatory ECG monitoring of ≥7 days with at least 1 atrial tachycardia/AF episode, tertiary care centre
- Participants
- 742 patients
- Outcome
- Symptom-rhythm correlation (SRC) for AT/AF events
Methodological detailssingle-centre
- Single-centre
Main finding
As reported in the abstract
Symptom-rhythm correlation
- Overall symptom-rhythm correlation (SRC) (range, 0-1.0)
- 0.39
- Presence of AT/AF increased odds of symptoms (adjusted)
- ∼8.3 times, P < .01
- Prior AF rhythm control treatment and lower heart rate associated with worse SRC (multivariable)
- P < .01
Observational data: associations, not effects.
