The 31 pages that link to Syncope, each with the reason it gives.

• EpilepsyCompared with: Syncope can include movements that are mistaken for an epileptic seizure.

• Orthostatic hypotensionRelated: Severe orthostatic hypotension can reduce brain perfusion enough to cause fainting.

• SeizureCompared with: Fainting can resemble a seizure but results from reduced cerebral blood flow.

• Opioid overdoseCompared with: Fainting can resemble an overdose collapse but does not by itself explain persistent slow breathing.

• Cardiac arrestCompared with: Syncope usually resolves spontaneously, unlike ongoing cardiac arrest without circulation.

• BradycardiaRelated: Severe bradycardia can reduce brain perfusion and cause fainting.

• Status epilepticusCompared with: Fainting can include brief movements that mimic a seizure but usually resolves spontaneously.

• ComaCompared with: Syncope usually resolves quickly, unlike the sustained unarousable state of coma.

• Focal SeizureCompared with: Syncope can mimic a seizure but results from reduced cerebral perfusion, not focal epileptic activity.

• Long QT syndromeRelated: A self-terminating ventricular arrhythmia can cause abrupt fainting in long-QT syndrome.

• BaroreflexRelated: Failure to maintain pressure, or an excessive reflex response, can lead to fainting.

• Falls in older adultsCompared with: A fall may follow syncope, but many falls occur without loss of consciousness.

• Ventricular tachycardiaRelated: Reduced circulation during ventricular tachycardia can cause fainting.

• ShockCompared with: Syncope is a temporary symptom, whereas shock is persistent systemic circulatory failure.

• Vasovagal syncopeNarrower topic: Vasovagal syncope is one cause within this broader clinical category.

• HypotensionRelated: A sudden pressure drop can trigger fainting by reducing cerebral perfusion.

• Torsades de pointesRelated: A self-terminating torsades episode can abruptly reduce cerebral blood flow and cause fainting.

• Supraventricular tachycardiaRelated: A very rapid or prolonged episode can reduce cerebral blood flow and cause fainting.

• Holter monitorRelated: Monitoring may help investigate suspected rhythm-related fainting when episodes are intermittent.

• Aortic stenosisRelated: Exertional fainting can occur when a fixed valve obstruction limits increased cardiac output.

• ArrhythmiaRelated: A rhythm that suddenly limits cardiac output can cause fainting.

• HyperventilationRelated: Marked hypocapnia can reduce cerebral blood flow and contribute to fainting.

• Absence seizureCompared with: It can resemble a seizure, but results from reduced cerebral blood flow rather than epileptic activity.

• PalpitationsCompared with: Fainting with palpitations is more concerning than the sensation alone.

• DizzinessCompared with: Presyncope may feel like dizziness, while syncope includes actual loss of consciousness.

• Febrile seizureCompared with: Fainting can include brief jerking movements, creating confusion with a seizure.

• Temporal lobe epilepsyCompared with: Fainting can be mistaken for a seizure, but its cause and clinical course differ.

• AsphyxiaCompared with: Both can involve collapse, but syncope is defined by temporary loss of brain blood flow.

• LethargyCompared with: A faint is a discrete loss of consciousness, not the ongoing sluggishness described by lethargy.

• Sick sinus syndromeRelated: Long pauses or very slow rates can temporarily reduce cerebral blood flow.

• LightheadednessCompared with: Complete loss of consciousness distinguishes syncope from lightheadedness alone.
