Cough syncope syndrome

Introduction to cough syncope syndrome Cough syncope syndrome (coughsyncopesyndrome) refers to a group of conditions that can cause a transient loss of consciousness during cough and can quickly recover without leaving any sequelae. basic knowledge The proportion of the disease: the incidence rate of the elderly over 60 years old is about 0.0002%-0.0008% Susceptible people: no specific population Mode of infection: non-infectious Complications: headache

Causes of cough syncope syndrome

(1) Causes of the disease

More common in male patients with chronic respiratory diseases (such as chronic bronchitis, emphysema, etc.), can also be seen in atrioventricular block, obstructive cardiomyopathy, carotid sinus allergy, atherosclerosis.

(two) pathogenesis

The mechanism is that the chest is coughing, the intra-abdominal pressure rises sharply, the blood volume of the vein is reduced, the cardiac output is reduced, and the transient cerebral ischemia is caused. At the same time, the chest and the intra-abdominal pressure during cough can also be rapidly increased. The subarachnoid space is transmitted to the cranium, which increases the intracranial pressure and compresses the cerebral blood vessels to cause cerebral ischemia. In addition, the cerebrospinal fluid pressure rises rapidly during coughing, which can cause the brain to be compressed and produce an oscillating effect.

Cough syncope prevention

There is no effective preventive measure for this disease. Early detection and early diagnosis are the key to the prevention and treatment of this disease.

Cough syncope syndrome complications Complications

headache.

Cough syncope syndrome symptoms Common symptoms Loss of consciousness pale pale twitching hair stunned dizziness

Immediately after severe cough, loss of consciousness occurs, body muscle tension is low, pale complexion, weak pulse, standing person may fall, severe facial muscles and limbs convulsions, complexion blemishes, etc., mild patients can be unconsciously lost, lasting seconds to minutes The breathing gradually rules, and then the consciousness is clear, there is no obvious headache after the attack, lethargy, etc., the number of attacks is uncertain.

Examination of cough syncope syndrome

Cerebrospinal fluid pressure rises rapidly during coughing.

In the episode, the EEG showed bilateral symmetric symmetry spindle waves with a frequency of 2 to 3 weeks/s for 3 to 4 s. The interictal EEG was normal.

Diagnosis and diagnosis of cough syncope syndrome

diagnosis

The medical history has the history of the above-mentioned diseases, and can be diagnosed based on the above clinical manifestations and auxiliary examinations and the elimination of syncope caused by epilepsy or other causes.

Differential diagnosis

Syncope caused by epilepsy or other causes.
