“…The causes of US are known to heterogeneous, with 18∼65% of US contributed to arrhythmic causes as previously reported [13,14,15,16,17,18]. Another study used ILR to diagnose etiology in patients with unexplained syncope and found that and arrhythmic causes were responsible for syncope in 69% of these patients [19]. Our results showed that US was more closely associated with syncope recurrence when compared with NMS.…”

Purpose: Recurrent syncope leads to poor functional status and psychiatric impairment in patients with syncope. The aim of the study was to prospectively analyze the risk factors attributed to syncope recurrence. Materials and Methods: Between 2009 and 2010, 289 patients with all cause of syncope visited our institution. Syncope recurrences were followed for 1 year by telephone interview every 3 months. Results: We diagnosed 181 (63%) patients with neurally mediated syncope (NMS), 39 (13%) with orthostatic hypotension, 34 (12%) with cardiac syncope, and 35 (12%) with unexplained syncope. During the 1-year follow-up period, 19 (6.6%) patients suffered recurrent syncope. Kaplan-Meier curves showed that recurrent syncope was observed more often in patients with unexplained syncope compared with those with NMS (p < 0.01), and also observed more often in patients with six previous syncopal episodes compared to those with fewer episodes (p = 0.02). Cox regression analysis showed that the recurrence of syncope was significantly associated with more than six previous syncopal episodes (HR 5.38, 95% CI 1.17-24.71, p = 0.03) and that there was a tendency for association between recurrence of syncope and unexplained syncope (HR 6.13, 95% CI 0.96-39.1, p = 0.05). Conclusions: Patients with previous frequent syncopal episodes or unexplained syncope had higher rates of syncope recurrence during the follow up period.

“…The ability of ILRs to continuously monitor cardiac rhythm over long periods makes them powerful diagnostic tools for patients with unexplained syncope [6]. Using ILRs, in the majority of patients a diagnosis can be established by performing long-term symptom -rhythm correlation [7][8][9]. Cardiac arrhythmias as primary cause of syncopes are common and most of them are caused by bradyarrhythmic events [10].…”

“…The diagnostic yield of any ECG monitoring strategy increases as the monitoring period is increased; ILRs have a significantly greater diagnostic yield than 24-h Holter, 30-day event, or 30-day ambulatory cardiovascular telemetry monitoring [6]. The PICTURE registry was a prospective, multicenter, observational study that followed 570 patients with recurrent unexplained pre-syncope or syncope who received an ILR [7].…”

“…We reported the clinical utility of a wireless ILR, which was commercially available in the United States for a brief period, in 50 consecutive patients in whom syncope was either recurrent, associated with trauma or an abnormal ECG [6]. A diagnosis was made in nearly a third of our patients.…”
