Vasovagal syndrome: understanding and treatment

Vasovagal syndrome, also known as Lewis syndrome or bradycardic-hypotonic syndrome, is a nervous system disorder that manifests itself through reflex reactions that include a decrease in heart rate (bradycardia) and a drop in blood pressure (hypotension). It gets its name from its connection with two main components - the blood vessels (vas) and the vagus nerve (nervus vagus).

Vasovagal syndrome occurs in a variety of situations that can stimulate the vagus nerve, such as emotional stress, fear, prolonged standing, monotonous or repetitive movement, and certain triggers, including painful or unpleasant signals. When the vagus nerve is activated, its tone increases, which leads to reflex changes in cardiac activity and vascular tone.

The main symptoms of vasovagal syndrome include dizziness, loss of consciousness (syncope), feeling weak, pale skin, sweating, nausea and vomiting. In some cases, convulsions and epileptic seizures may occur. Symptoms usually occur suddenly and may last for a few seconds to several minutes.

The diagnosis of vasovagal syndrome is based on typical clinical manifestations and the exclusion of other possible causes of symptoms. Your doctor may do a heart test, including an ECG (electrocardiogram), to rule out heart arrhythmias or other heart problems. In some cases, additional tests may be recommended, such as stress tests or 24-hour cardiac monitoring.

Treatment of vasovagal syndrome is aimed at reducing the frequency and severity of symptoms. In most cases, lifestyle changes and precautions are recommended, such as avoiding prolonged standing, avoiding triggers that cause symptoms, and using relaxation techniques to reduce stress. In some cases, medications such as beta blockers or anticholinergics may be prescribed to reduce vagus nerve activity.

In most cases, vasovagal syndrome is not life-threatening and can be well controlled. However, in some cases, especially if there is syncope or loss of consciousness, medical attention and further testing may be needed to rule out other serious causes of symptoms.

In conclusion, vasovagal syndrome is a nervous system disorder characterized by reflex changes in cardiac activity and vascular tone. It can manifest through various symptoms such as dizziness, loss of consciousness, feeling weak and nausea. Diagnosis is based on typical clinical manifestations, and treatment is aimed at reducing symptoms and improving the patient's quality of life. If you suspect vasovagal syndrome, it is important to see your doctor for proper diagnosis and treatment recommendations.
