Cough syncope is generally due to increased vagal tone and decreased peripheral sympathetic tone, which causes bradycardia and hypotension. Cough syncope results from a vasovagal reflex caused by an increase in thoracic pressure.

How do I stop cough syncope?
In patients with idiopathic cough syncope, direct suppression of the sensory cough reflexes is indicated. Such medications include codeine, lidocaine, dextromethorphan, chlophedianol, levodropropizine, and morphine.
What are the symptoms of cough syncope?
The syndrome of cough syncope, also called “laryngeal ictus” (from Latin ictus, which means “blow, stroke, or thrust”) is characterized by paroxysmal cough, facial congestion, cyanosis, and loss of consciousness, which typically occurs within seconds followed by rapid recovery.
What causes coughing syncope?
Cough syncope can result from transient increases in intracranial pressure and consequent reduction in cerebral blood flow due to abnormally high internal jugular vein pressures transmitted from the thoracic cavity because of incompetent internal jugular vein valves (96).
Cough Syncope
How long does cough syncope last?
Cough syncope, also called “tussive syncope”, is a well-recognized syndrome for about 70 years, in which loss of consciousness usually occurs immediately after a violent cough or prolonged bouts of violent coughing, lasting for seconds with rapid restoration of full consciousness.
What causes you to pass out when coughing?
Also, with severe coughing episodes, the pressure inside the chest increases further affecting the blood flow to and from the heart. As a result, the heart rate slows down and with interrupted blood flow, the brain receives less oxygen, ultimately causing you to pass out or faint.
What causes cough induced syncope?
Cough syncope is generally due to increased vagal tone and decreased peripheral sympathetic tone, which causes bradycardia and hypotension. Cough syncope results from a vasovagal reflex caused by an increase in thoracic pressure.

Can you vasovagal from coughing?
Objectives: Cough syncope occurs immediately after coughing. Cough syncope rapidly recovers in 1-2 second. Although cough syncope has been classified in vasovagal syncope, it may differ from pathogenetic mechanism. Physicians should be aware of this easily recognizable cough induced syncope.
What is it called when you cough and pass out?
Cough syncope is a transient loss of consciousness associated with coughing. Cough syncope was first described in the literature by Charcot in 1876 under the name of laryngeal vertigo.

Is cough syncope serious?
Cough syncope is an important, but frequently overlooked, feature of chronic cough. Defined as loss of consciousness during coughing, cough syncope is a distressing and potentially fatal condition if an episode occurs whilst driving [25].
How do you diagnose cough syncope?
The differential diagnosis of cough syncope includes epilepsy and cataplexy. Cough syncope may present with clonic movements during the syncopal episode which might be confused with epilepsy. Careful history is needed to differentiate these two conditions as cough syncope always occurs with a coughing episode.
