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 you stop a cough syncope?
Treatment of cough syncope involves optimal management of underlying pulmonary disease. 5, 16 A follow up review of patients with cough syncope at Mayo clinic showed that smoking cessation and treatment of cough is effective in relieving symptoms of cough syncope.
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 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.
Cough Syncope
Is cough syncope common?
Cough syncope is usually benign and fatalities occur only in 1–2% of the patients primarily in those with underlying cardiovascular disease. Several mechanisms have been postulated for the explanation of cough syncope in the literature.
Is cough syncope rare?
Although it is not uncommon for patients with CMI to present with respiratory complaints, cough syncope is a rare presenting symptom.
Why do I lose consciousness when I cough?
Fainting due to coughing is a condition called cough syncope. It usually occurs with persistent, prolonged and severe episodes of coughing. It is more common in men than women. What happens is while coughing the autonomic nervous system reflexes connecting the brain, heart and the respiratory system get stimulated.

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 happens during 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.
Kthv: Dr. Nosheen Mian Discusses Cough Syncope
Why does cough syncope happen?
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).
What causes Tussive syncope?
By the mid-20th century, a number of small studies and case series suggested that post-tussive syncope was a consequence of markedly elevated intrathoracic pressures induced by coughing [29–31]. This results in reduced venous return and subsequent decreased cardiac output resulting in syncope [31].
