BACKGROUND: A high P-wave duration and dispersion (Pd) have been reported to be a prognostic factor for the occurrence of paroxysmal atrial fibrillation (PAF), a condition linked to obstructive sleep apnea (OSA). We tested the hypothesis of whether a short-term increase of P-wave duration and Pd can be induced by respiratory manoeuvres simulating OSA in healthy subjects and in patients with PAF. METHODS: 12-lead-electrocardiography (ECG) was recorded continuously in 24 healthy subjects and 33 patients with PAF, while simulating obstructive apnea (Mueller manoeuvre, MM), obstructive hypopnea (inspiration through a threshold load, ITH), central apnea (AP), and during normal breathing (BL) in randomized order...

BACKGROUND: Recurrent atrial fibrillation (AF) after successful cardioversion can be predicted by obstructive sleep apnea (OSA) diagnosed by polysomnography. However, it is not known whether the validated STOP-BANG questionnaire can predict AF recurrence after radiofrequency ablation (RFA). Our objective is to determine the prevalence of unrecognized OSA in patients with AF and its relation to freedom from AF after RFA. METHODS: Validated surveys were administered to 247 consecutive AF patients following radiofrequency ablation from January to October 2011...

AIMS: There is preliminary evidence for a link between obstructive sleep apnoea (OSA) and arrhythmias such as paroxysmal atrial fibrillation (PAF) and sudden cardiac death but underlying mechanisms remain largely unknown. METHODS AND RESULTS: In this interventional crossover study, we evaluated whether intrathoracic pressure changes, induced by simulated OSA, trigger premature cardiac beats, and alter measures of ventricular repolarization [QTc and Tpeak-to-Tend (TpTec) intervals] in patients with PAF...

Left arial (LA) function, defined according to conduit, reservoir and booster functions, is closely linked to left ventricular (LV) mechanics, particularly during diastole. Right ventricular pacing (RVP) is thought to impair LA diastolic restoring forces through alteration of ventricular activation. The aim of this study was to determine whether the LA functional reservoir estimated as the change in mean LA ejection fraction (EF) immediately after RVP, and for the second and for the third beats after RVP, predicts clinical outcome in patients with paroxysmal atrial fibrillation (AF) who have undergone catheter ablation (CA)...

Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with relevant morbidity and mortality. Besides hypertension, valvular disease and cardiomyopathy, mainly ischemic and dilated, also other conditions like obesity, alcohol abusus, genetic factors and obstructive sleep apnea (OSA) are discussed to contribute to the progression from paroxysmal to persistent AF. The prevalence of OSA among patients with AF is 40-50%. OSA is characterized by periodic or complete cessation of effective breathing during sleep due to obstruction of the upper airways...

INTRODUCTION: Metabolic syndrome (MS) and obstructive sleep apnea (OSA) are well-known independent risk factors for atrial fibrillation (AF) recurrence. This study evaluated ablation outcome in AF patients with coexistent MS and OSA and influence of lifestyle modifications (LSM) on arrhythmia recurrence. METHODS AND RESULTS: We included 1,257 AF patients undergoing first catheter ablation (30% paroxysmal AF). Patients having MS + OSA were classified into Group 1 (n = 126; 64 ± 8 years; 76% male)...

BACKGROUND: The relationship between obstructive sleep apnea (OSA) and increased risk for atrial fibrillation (AF) has been well established in previous studies. The relationship between OSA and silent AF is unknown. We hypothesized that patients with OSA but no known history of AF are at an increased risk for the arrhythmia and may be detectable by prolonged electrocardiogram (ECG) monitoring. In this study, we examined whether 7 days of extended cardiac monitoring with an ECG event recorder is an effective screening tool to detect intermittent, silent AF in patients with severe OSA...

BACKGROUND: Obstructive sleep apnoea (OSA) and atrial fibrillation (AF) are two conditions highly prevalent in the general population. OSA is known to cause haemodynamic changes, oxidative stress, and endothelial damage, and therefore promote vascular and heart remodelling which results in AF triggering and exacerbation. Coexistence of OSA and AF influences the course of both diseases, and therefore should be taken into consideration in patient management strategy planning. AIM: To assess the prevalence of OSA in Polish AF patients, and to describe the clinical characteristics of patients with concomitant OSA and AF...

BACKGROUND: Obstructive sleep apnea (OSA) has several negative effects on the heart including increase in myocardial end-systolic stress, venous return and sympathetic activity, all potential stimuli of left ventricular (LV) hypertrophy. The impact of the severity of OSA on LV geometry is unknown. We hypothesized that OSA is related to concentric LV geometry. METHODS: One hundred and fifty-seven patients with suspected OSA underwent echocardiography, ambulatory 24-h blood pressure and ECG monitoring...
