The use of compression hose and pacemakers has been recommended. Have there been any previous syncopal episodes? Most patients with VVS do well after specialist evaluation, reassurance . Limited data exist for the role of drugs in the treatment of vasovagal syncope in older patients. This is supported by the observation that patients with syncope associated with abrupt bradycardia displayed a better response to cardiac pacing therapy than those with gradual onset bradycardia[71].

There may be a familial component with a family history of benign or simple fainting. It is essential to discriminate syncope from other disorders with transient LOC, e.g. Vasovagal syncope, Midodrine, Adrenergic β-antagonists, Serotonin uptake inhibitors. An anxious patient may also have signs suggestive of hyperventilation. [] compares the effectiveness in reducing repetitive syncope after treatment with CNA and pacing via pacemaker using various pacing techniques.Confronting electrical therapy techniques with physiological modulation techniques. Neurally-mediated syncope has a broad clinical spectrum which ranges from typical vasovagal syncope on one hand, to those situations in which reflex syncope occurs with uncertain, or even apparently absent, triggers or prodromes, on the other hand. Vasovagal syncope has been associated with chronic pain procedures, phlebotomy, and musculoskeletal injections. An informative and instructive talk with the patient about the benign nature and prognosis is the first step in the treatment of patients with vasovagal syncope. At this time, if the patient’s history is typical with no concerning features and a normal physical examination and electrocardiogram, the diagnosis of vasodepressor syncope can be made clinically. A complete neurological examination should be performed, as neurological disease may present with a syncopal episode. In this paper the management and treatment of vasovagal syncope focuses on patients with vasovagal syncope. An ILR is a useful tool to detect or exclude hazardous cardiac arrhythmia. Questions asked include: Did the patient have any preceding symptoms or prodrome? Was ist eine Synkope? One hour after drug or placebo administration, patients underwent 60-degree head-up tilt lasting 40 min (unless hypotension or bradycardia developed first). Establishing the cause and ruling out other pathological causes. Other causes of syncope must be considered and ruled out prior to establishing a diagnosis of vasovagal syncope.

In some cases syncope occurs without any prodromal symptoms[22]. Analysis of the pre-syncopal phase of the tilt test without and with nitroglycerin challenge. Currently the most used protocols are the intravenous isoproterenol test, and the protocol using sublingual nitroglycerin[29,30]. Activation of these sympathetic and parasympathetic reflex loops instigates either hypotension (vasodepressor type) or bradycardia (cardioinhibitory type) or both (mixed type)[4]. Increasing fluid with water and electrolyte drinks and liberalizing salt intake is usually sufficient . This should include questioning about any history of cardiac disease, cardiomyopathy, arrhythmias, need for pacemaker or implantable cardiac defibrillators, and sudden or unexplained death. Syncope is defined as a transient and self-terminating loss of consciousness (LOC) with rapid onset, short duration combined with spontaneous, prompt and complete recovery. Head-up tilt-table testing is contraindicated in patients with critical obstructive cardiac disease (such as critical proximal coronary artery stenosis, critical mitral stenosis or severe left ventricular outflow obstruction) or critical cerebrovascular stenosis. While vasovagal syncope is commonly associated with interventional pain procedures, its occurrence during peripheral nerve block procedures has not been reported. Further testing is pursued to evaluate for the possible rare but potentially ominous causes, including the risk for sudden death. Copyright © 2023 Haymarket Media, Inc. All Rights Reserved Most experts recommend a standard 12-lead electrocardiography (ECG) as a routine investigation to rule out heart rhythm disturbances[22]. The patients were randomized to receive a nonpressor dose of midodrine (5 mg) or placebo on day 1 and the opposite on day 3. Has the patient had any intercurrent illness accompanied by fever or dehydration? In the older patients the diagnostic work-up is more complex, the prognosis may not necessarily follow the benign course commonly observed in younger patients and therapy often remains uncertain. In patients who present immediately after an episode, an evaluation should include: In patients who present to clinic for evaluation of a remote episode of syncope, the evaluation should include an electrocardiogram, even when the history is suggestive of vasovagal syncope. Colman N, Nahm K, Ganzeboom KS, Shen WK, Reitsma J, Linzer M, Wieling W, Kaufmann H. Epidemiology of reflex syncope.

It has to be administered 3 times per day starting with 5 mg, because of a half-life of only 2-3 h. In 3 small randomized, placebo-controlled trials, midodrine had a beneficial effect on symptom frequency, symptoms during head-up tilt, and quality of life[57-59] (Table ​(Table1).1). The blood pressure should be stable after standing for 10 minutes. If medical therapy with fludrocortisone, a beta blocker, or alpha agonist is required, complications such as weight gain, fatigue, and dry mouth may be noted.

Central as well as peripheral mechanisms have been implicated in its pathogenesis; however their relative contribution is not fully elucidated. In this paper the authors discuss the evaluation for syncope and the cost of evaluation per patient. The pathophysiology of vasovagal syncope is characterized by a reflex activation triggering a rapid decrease in heartbeat and a reduction of vascular tone[15].

It is important to underline that doubts remain as to whether the pathophysiological mechanisms of pre-syncope are the same as in syncope. This chapter focuses on vasovagal (or vasodepressor syncope). Gastroparesis: Gastroparesis occurs when damage to a vagus nerve stops food from moving into your intestines from your stomach. Trauma during a syncopal episode cannot be ignored and suggests that the syncope is not benign. In these patients, determination of the hemodynamic mechanism of spontaneous syncope by means of an external or implantable cardiac monitor seems to be the most advisable option for optimal management.

Beta blockers are occasionally used to decrease the catecholamine surge; however, if there is bradycardia this may worsen syncope. Am Fam Physician. The role of pacing is unclear at present. This leads to vasodilation with resultant hypotension and cerebral hypoperfusion. Syncope. If syncope is caused by an arrhythmia, congenital heart defect, seizure, or a metabolic disease, therapy is directed towards the management of this underlying cause to prevent recurrence. Was the patient standing up quickly after prolonged bed rest? A family history of congenital deafness raises the possibility of prolonged QTc (Jervell Lang Nielson syndrome).

The main aim of the evaluation is to distinguish patients with a benign cause like vasovagal syncope from patients with life-threatening conditions like arrhythmias, severe cardiovascular diseases or neurological causes to minimize the risk of sudden cardiac death. Encouraging intake of fluid and salt (especially in warm climates and with exercise). The value and cost-effectiveness of ILR is well documented[42-44]. The reflex syncope includes different types of syncope which all show a typical trigger circumstance and an induction of cardiovascular reflexes. A recently published meta-analysis of all studies suggested a non-significant 17% reduction in syncope from the double-blinded studies, and an 84% reduction in the studies where the control group did not receive a pacemaker[70]. The mechanisms responsible for this are complex and involve both depression of cardiac . Is there an abnormal second heart sound and/or click that may suggest pulmonary hypertension?
