“…An account by a witness is often extremely helpful and worthy of pursuit. The ECG is infrequently diagnostic (yield <5%) 23 as well as to distinguish between seizures and syncope. 28 A point scoring system considers both the presence and absence of key historical features in coming to a diagnosis.…”

“…2 On the other hand, syncope is a common chief complaint of patients in the emergency department accounting for approximately 3% of visits. 3,4 There are many categories of syncope according to the underlying cause: cardiac causes (arrhythmic and non-arrhythmic), seizure disorder, vaso-vagal, and orthostatic causes, medications and other infrequent causes such as stroke or transient ischaemic attack. Aetiology remains unknown in more than a third of patients, despite clinical and instrumental evaluation.…”

Syncope in patients with pulmonary embolism: comparison between patients with syncope as the presenting symptom of pulmonary embolism and patients with pulmonary embolism without syncope R Castellia , P Tarsia a , C Tantardini a , G Pantaleo b , A Guariglia a and F Porro a Abstract: Syncope as an initial presentation of pulmonary embolism occurs in 10% of patients. We compared clinical and instrumental parameters in patients with syncope as the presenting symptom of pulmonary embolism and in patients with documented pulmonary embolism without syncope. Seventy patients with the diagnosis of pulmonary embolism and apparently stable clinical conditions were evaluated. They were divided in two groups: 10 patients with syncope as the presenting symptom of pulmonary embolism (group 1) and 60 patients without syncope (group 2). Patients with syncope showed a more pronounced tendency to present with main pulmonary artery embolus than patients without syncope (contingency coef cientˆ0.301, p < 0.04; one-tailed). However, despite the evidence that patients with syncope have signi cant reductions in systolic and=or diastolic blood pressure, shock was not observed in any patient. In no case was thrombolytic treatment given and all patients received standard anticoagulation with unfractioned heparin and oral anticoagulant. We suggest that syncope in the setting of non-massive pulmonary embolism may be due to vaso-vagal mechanism that can lead to a reduction of arterial blood pressure when central artery thrombosis is involved.

“…10,33,[37][38][39][40] Presence of cardiac diseases, ventricular arrhythmias, conduction system disease, and advanced age are predictors of poor survival. The lack of separation in the survival curve, however ( Figure 3A), suggests that these patients who have syncope while driving may not have higher mortality than the general population, although the event rate is low.…”

Background-The risk of syncope occurring while driving has obvious implications for personal and public safety. We aimed to define the clinical characteristics, causes, and prognosis of syncope while driving. Methods and Results-In this case-control study of consecutive patients evaluated for syncope from 1996 through 1998 at an academic medical center, we documented causes, clinical characteristics, and recurrence of syncope while driving. Of 3877 patients identified, 381 (9.8%) had syncope while driving (driving group). Compared with the 3496 patients (90.2%) who did not have syncope while driving, the driving group was younger (Pϭ0.01) and had higher percentages of male patients (PϽ0.001) and patients with a history of any cardiovascular disease (Pϭ0.01) and stroke (Pϭ0.02). Syncope while driving was commonly caused by neurally mediated syncope (37.3%) and cardiac arrhythmias (11.8%). Long-term survival in the driving group was comparable to that of an age-and sex-matched cohort from the Minnesota population (Pϭ0.15). Among the driving group, syncope recurred in 72 patients, 35 of whom (48.6%) had recurrence Ͼ6 months after the initial evaluation. Recurrences during driving happened in 10 patients in the driving group, 7 of which (70%) were Ͼ12 months after the initial evaluation. Conclusions-In our study, neurally mediated syncope was the most common type of syncope while driving. The causes of syncope, the late recurrences of syncope (during Ն6 months of follow-up), and the overall low incidence of recurrent syncope while driving provide useful information to supplement current recommendations on driving for these patients.
