Non-valvular new onset supraventricular arrhythmia (SVA; atrial fibrillation, atrial flutter, atrial tachysystolia) is the most frequent rhythm disorder in surgical and non-surgical intensive care units (ICUs), occurring in 4.5% to 46% of critically ill patients [1-5]. Although SVA in critically ill patients is now recognized as an indicator of illness severity, its independent relationship with mortality is the subject of debate [1,4-6]. Regarding morbidity, recent data show that in-hospital arterial thromboembolic events (ATEs) are not rare . A multicentre retrospective study, with approximately 50,000 patients hospitalized for severe sepsis, reported that SVA was associated with an increased adjusted risk of in-hospital ischaemic stroke (2.6% vs 0.6%; odds ratio 2.70 [2.05-3.57]; P < 0.001) .
