Syncope is an abrupt and transient loss of consciousness caused by cerebral hypoperfusion. It accounts for 1% to 1.5% of emergency department visits, resulting in high hospital admission rates...

Syncope is an abrupt, transient, and complete loss of consciousness associated with an inability to maintain postural tone; recovery is rapid and spontaneous. The...

2018年4月1日 · The American College of Cardiology (ACC), American Heart Association (AHA), and Heart Rhythm Society (HRS) have released guidelines to assist physicians in evaluating and treating syncope.

2024年11月5日 · Syncope is a clinical syndrome in which transient loss of consciousness (TLOC) is caused by a period of inadequate cerebral blood flow and oxygenation, most often the result of an abrupt drop of systemic blood pressure.

If the cause of syncope is determined, is there an effective therapy to prevent recurrent syncope, prevent syncope-related nonfatal outcomes (injury, diminished healthcare–related QoL, lost workdays), or improve survival?

Syncope is an abrupt, transient, and complete loss of consciousness associated with an inability to maintain postural tone; recovery is rapid and spontaneous. The condition is common, resulting in about 1.7 million emergency department visits in 2019.

2017年3月1日 · A standardized approach to syncope evaluation reduces hospital admissions and medical costs, and increases diagnostic accuracy. The initial assessment for all patients presenting with syncope includes a detailed history, physical examination, and electrocardiography.

2016年4月1日 · Syncope is a common problem in children and adolescents, but the diagnostic yield for most tests used in its evaluation in pediatric patients is low, and testing should be guided by a careful history and physical examination.

2023年6月12日 · Syncope is a transient loss of consciousness and postural tone followed by spontaneous recovery. While there are numerous classification schemes used to further identify and manage underlying conditions that may lead to syncope, syncope ultimately results from decreased cerebral perfusion.

The 2017 American College of Cardiology/American Heart Association/Heart Rhythm Society syncope guidelines present a data-driven algorithm to initiate a workup for syncope and determine which...
