Introduction

Syncope is a common ailment in children, defined as a brief loss of consciousness and postural tone followed by a spontaneous recovery. Around 15% of youngsters under the age of 18 experience one or more syncopal episodes. Variability in clinical presentation of childhood syncope, along with confusion about the aetiology, often leads to an expensive and unnecessary inpatient or outpatient evaluation; the uncertainty also causes great concern for both parents and patients. Syncope in children can be caused by a variety of factors, including vasovagal dysfunction, hypertrophic cardiomyopathy, and seizure disorders. Despite the fact that several etiologies of syncope and their occurrence have been established in earlier studies, there has yet to be a comprehensive review that brings together data from multiple institutions in an orderly manner. The purpose of this study was to use a systematic review of the world's literature and Bayesian meta-analysis to establish a full differential diagnosis of childhood syncope, including relative probability and 95 percent credible intervals (CredIs) for each clinical entity. A compendium like this could be used as a reference for evaluating syncope in children [1].

The following criteria were met by eligible studies: (1) a minimum of 10 patients per report with a clinical diagnosis of syncope, according to the authors' criteria of syncope; (2) subjects aged 21 or younger; and (3) individuals who were part of a sequential retrospective or prospective group. This analysis was based on eleven studies with a total of 3700 patients that matched the inclusion criteria. A diagnosable cause of syncope was discovered in more than 80% of these patients. The most common cause of syncope in this study was determined to be vasovagal syncope. Patients with vasovagal syncope usually appear after their first episode of syncope, which is frequently preceded by a stressor such extended standing or mental strain. The absence of another cause or aetiology, a positive response to a head-up tilt test with a vasovagal reaction (hypotension and/or bradycardia), and no underlying chronic or acute illness are all diagnostic criteria for vasovagal syncope [2].

The prognosis for patients diagnosed with vasovagal syncope is usually favourable. Most people don't need drugs and can improve their health by changing their lifestyles, such as drinking more salt water. Blockers, hydrocortisone, fludrocortisone, midodrine, or serotonin reuptake inhibitors can be given in patients whose symptoms do not improve. In this investigation, postural orthostatic tachycardia syndrome was found to be the second most common cause of syncope. Patients usually present after their first syncopal episode, which is frequently accompanied by dizziness, palpitations, pallor, headache, and other symptoms. A 30-bpm increase in heart rate during a tilt-table test or a heart rate above 120 bpm within 10 minutes of tilting the table from horizontal to vertical position are diagnostic criteria. 4 Patients with POTS have a good prognosis. The vast majority do not necessitate the use of drugs. Midodrine, blockers, or serotonin reuptake inhibitors can be administered in people who have chronic symptoms. A careful history and physical examination, as well as, in a few cases, minimally invasive tests, were used to make diagnoses in many of the cases where a definitive cause was identified [3].

Future research should focus on providing a more thorough follow-up of patients who have suffered syncope, particularly when the cause is unknown, to see if the patient has recurring episodes, which could aid physicians in determining the cause. Furthermore, a more exact definition of syncope that includes a time range might be helpful in maintaining consistency in future investigations [4].

In conclusion, syncope is a very prevalent ailment among children. The current study, which is the first comprehensive analysis of syncope in children, indicates that the vast majority of occurrences are caused by benign reasons, with just a tiny number due to serious medical issues. Furthermore, these findings suggest that most syncopal episodes in children can be diagnosed with only minimally invasive testing, such as the tilt-table test, highlighting the importance of a thorough history and physical examination during management and discouraging the use of invasive procedures unless the history and physical indicate otherwise. Despite the study's limitations, it offers doctors with helpful information regarding the most prevalent causes of syncope in children, as well as a starting point for discussing probable etiologies and diagnostic tests with their patients and their families [5,6].
