After evaluating this article, participants will be able to:
1. Incorporate into clinical practice critical questions that should be asked when taking the history of a child who experienced syncope
2. Recognize key symptoms associated with pediatric syncope
3. Develop strategies to identify illnesses associated with syncope
While most syncopal events in children are benign, there are certainly serious syncope conditions which exist, mainly involving the cardiovascular system. Fifteen to 20 percent of children will have one episode with neurogenic syncope being the overall most common cause. The physical examination is normal in up to 96% of children.
Q. Are there any symptoms that can serve as a warning to providers when evaluating children who present with syncope?
A. In this study 72 percent of sudden cardiac arrest (SCA) victims were reported by their parents to have at least one cardiovascular symptom before SCA. The two most common symptoms were fatigue (44%) and near-syncope/lightheadedness (30%).
Citation: Drezner JA, Fudge J, Harmon KG etal. Warning symptoms and family history in children and young adults with sudden cardiac arrest. J Am Board Fam Med. 2012 Jul;25(4):408-15.
BACKGROUND: Children and young adults with undiagnosed cardiovascular disorders at risk for sudden death may have warning symptoms or significant family history that is detectable through screening. The objective of this study was to determine the prevalence of warning symptoms and family history in a cohort of children and young adults who suffered sudden cardiac arrest (SCA).
METHODS: A retrospective survey investigating warning symptoms and family history of cardiovascular disease was completed by families with a child or young adult who suffered SCA.
RESULTS: Eighty-seven of 146 families (60%) returned a completed survey. The SCA victims were an average age of 16 years (range, <5-29 years), 69% male, and 68% white. Seventy-two percent of SCA victims were reported by their parents to have at least one cardiovascular symptom before SCA, with fatigue (44%) and near-syncope/lightheadedness (30%) the two most common. Twenty-four percent of SCA victims had one or more (average 2.6; range, 1 to 10) events of syncope or unexplained seizure that remained undiagnosed as a cardiac disorder before SCA. Parents reported that cardiovascular symptoms first occurred, on average, 30 months (range, 19 to 71 months) before SCA; a symptom was brought to the attention of the child’s physician in 41% of cases. Twenty-seven percent of families reported a family member had suffered sudden death before age 50 because of a heart condition.
CONCLUSIONS: Many children and young adults who suffered SCA are reported to have cardiac symptoms or a family history of premature cardiac death. Syncope and unexplained seizure activity are distinct events but often go unrecognized as ominous signs of underlying cardiovascular disease. Physician education and increased public awareness regarding cardiovascular warning signs in the young may improve early detection of those at risk and prevent tragedies
Q. Are there any questions that should be asked when taking the history of a child who presents with syncope?
A. The presence of any prodromal symptoms may be an important differentiator between cardiac and non-cardiac syncope. Syncope during exercise is an ominous sign whereas patients with syncope following prolonged standing, being in a warm, crowded place or emotional concerns such as fear of pain are more likely to have non-cardiac syncope.

OBJECTIVES: This study was designed to investigate the value of history taking in identifying children with cardiac syncope, and to improve diagnostic efficiency and accuracy in children with cardiac syncope.
METHODS: The characteristics of a group of children and adolescents with cardiac syncope at the Pediatric Syncope Unit of five hospitals in China were compared with those with typical vasovagal syncope. 275 patients in Pediatric Syncope Unit were included.
RESULTS: A cardiac cause of syncope was established in 31 patients, autonomic-mediated reflex syncope in 214, non-syncopal attacks in 15, and in the remaining 15 the cause of syncope remained unexplained. Cardiac syncope was triggered by exercise, whereas vasovagal syncope by prolonged standing, warm-crowded place, and fear or pain emotion. Syncopal spells occurred at various positions in cardiac syncope. Children who had prodromal symptoms with cardiac syncope were significantly fewer than those with vasovagal syncope. Most children with cardiac syncope had history of abnormal electrocardiogram findings when compared with children suffering from vasovagal syncope. On multivariable analysis, history of abnormal electrocardiogram findings and exercise-triggered syncope were independent predictors of cardiac syncope.
CONCLUSION: Children and adolescents with a history of abnormal electrocardiogram findings and exercise-related syncope spells were at high risk for cardiac syncope.
Q. Are there any common illnesses that predispose children to syncope?
A. This study revealed that children with febrile illnesses can present with a chief complaint of syncope. Approximately 25% of febrile patients in this trial had orthostatic hypotension when compared to only 5% in the non-febrile comparison group.
Citation: Shalem T, Goldman M, Breitbart R etal. Orthostatic Hypotension in Children with Acute Febrile Illness. J Emerg Med. 2012 May 10. [Epub ahead of print]
BACKGROUND: Children presenting to the Pediatric Emergency Department (PED) with fever often describe symptoms such as lightheadedness, dizziness, fatigue, and weakness, and may appear pale. They may also present with a chief complaint of syncope. Such symptoms may result from orthostatic hypotension.
OBJECTIVE: To determine whether children with an acute febrile illness have a higher incidence of orthostatic hypotension compared to afebrile children.
METHODS: A prospective cohort study was conducted at the PED at Assaf Harofeh Medical Center, a university-affiliated hospital in Israel. Eighty children aged 4-18 years were recruited. Thirty-nine had fever (>38°C for 6-48h) and 41 were afebrile. All subjects had their blood pressure measured in the supine position (after 5min of rest) and again after standing for 3min. The main outcome measure was orthostatic hypotension, that is, a reduction of systolic blood pressure of at least 20mm Hg, or a fall in diastolic blood pressure of at least 10mm Hg within 3min of standing.
RESULTS: There were no differences between the groups in gender, age, height, or weight. Orthostatic hypotension was found in 10/39 (25.6%) of febrile children and in 2/41 (5%) of afebrile children (p=0.012).
CONCLUSIONS: The incidence of orthostatic hypotension among febrile children in the PED is high, and may explain common symptoms such as dizziness or syncope. Such patients should be instructed to drink properly and to avoid rapid changes in body posture.
SummaryWhile most cases of syncope in children are benign, it is imperative to keep some key diagnoses in mind when evaluating these patients. Hypertropic cardiomyopathy is a common cause of sudden cardiac arrest. ECG findings may reveal small, deep Q wave (< 40 msecs) in the inferior and lateral leads along with high voltage. The murmur is accentuated by Valsalva maneuvers and standing. Check for a prolonged QT interval as these patients are at risk for ventricular arrhythmias such as torsades de pointes. Syncope during exercise is an important indicator of a cardiac cause. Febrile children may be more prone to orthostatic hypotension due to insensible fluid losses and therefore attention to hydration should be an integral aspect of care.
