The present prospective cohort study (not randomized) analyses the value of screening and treatment of SAHS in the management of patients with AF refractory to antiarrhythmics drugs, potentially candidates for ablation.
Patients at low risk of suffering from SAHS will follow conventional management of their AF, according to the usual criteria of the Arrhythmia Unit. Patients with high or intermediate risk of SAHS, will undergo respiratory polygraphy. If the result is positive, they will be treated as standard for this syndrome and their heart rate will be monitored for 3 months. After this, the patient's arrhythmic load will be reevaluated differentiating patients into two groups, those that must be ablated from those that have improved their condition and the clinical criteria is no longer ablation but follow-up.
Patients with paroxysmal or persistent atrial fibrillation
Recurrent atrial fibrillation despite treatment with at least one class I or III antiarrhythmic
No previous diagnosis of apnea-hypopnea syndrome
Patients <18 years
Pregnant women
Doubts about the patient's ability to perform a home respiratory polygraphy
Doubts about the patient's ability to acquire rhythm records with the Kardia system (smartphone required)
Sequential
Treatment of SAHS
Other interventionPatients diagnosed with SAHS will be treated in the Pneumology Service according to usual practice (dietary hygienic measures, CPAP, etc.).
