What is the cause of Brugada syndrome?
Their brother Ramon Brugada was the first to describe one potential genetic cause in 1998. While many of those with Brugada syndrome do not have any symptoms, Brugada syndrome may cause fainting or sudden cardiac death due to serious abnormal heart rhythms such as ventricular fibrillation or polymorphic ventricular tachycardia.
What is the PMC code for Brugada syndrome?

How common are ICD-related complications in patients with Brugada syndrome?
Twenty-one patients (20%) had other ICD-related complications (incidence rate 1.4% person-year). Three patients (2.9%) died (one electrical storm and two noncardiovascular deaths). ICD therapy is an effective therapy in high-risk patients with Brugada syndrome, but it is associated with a significant risk of device-related complications.
Which mutations in SCN5A are associated with Brugada syndrome?
Mutations in SCN5A associated with Brugada syndrome generally cause the flow of sodium ions to decrease. However, only 20% of cases of Brugada syndrome are associated with mutations in SCN5A, as in the majority of patients with Brugada syndrome genetic testing is unable to identify the genetic mutation responsible.

What is Brugada syndrome?
8% of sudden cardiac death. Brugada syndrome ( BrS) is a genetic disorder in which the electrical activity within the heart is abnormal. It increases the risk of abnormal heart rhythms and sudden cardiac death. Those affected may have episodes of passing out.
What is the abnormal heart rhythm in Brugada syndrome?
The abnormal heart rhythms seen in Brugada syndrome often occur at rest, following a heavy meal, or even during sleep. These situations are linked to periods when the vagus nerve is activated, referred to as periods of high vagal tone. Abnormal heart rhythms may also occur during fever or following excessive alcohol.
What causes Brugada ECG?
A long list of factors that can generate a Brugada ECG pattern have been described, including certain medications, electrolyte disturbances such as a decrease in the levels of potassium in the blood, and a reduction in blood supply to key areas of the heart , specifically the right ventricular outflow tract.
How does Brugada syndrome affect the heart?
As a genetic condition, the syndrome is ultimately caused by changes to a person's DNA, known as genetic mutations. The first mutations described in association with Brugada syndrome were in a gene responsible for a protein or ion channel that controls the flow of sodium ions through the cell membrane of heart muscle cells – the cardiac sodium channel. Many of the genetic mutations that have subsequently been described in association with Brugada syndrome influence the sodium current in some way, or affect other ionic currents.
What does an ICD do?
An ICD can also function as a pacemaker, preventing abnormally slow heart rates that can also occur in people with Brugada syndrome.
What is an ICD device?
In people felt to be at higher risk of sudden cardiac death, an implantable cardioverter-defibrillator (ICD) may be recommended. These small devices implanted under the skin continuously monitor the heart rhythm. If the device detects a potentially life-threatening arrhythmia it can give the heart a small electric shock, stunning the heart back into a normal rhythm. An ICD can also function as a pacemaker, preventing abnormally slow heart rates that can also occur in people with Brugada syndrome.
Is Brugada syndrome autosomal dominant?
Genetics. Brugada syndrome is inherited in an autosomal dominant manner, meaning that only one copy of the defective gene is needed to produce the syndrome. However, a person diagnosed with the condition may be the first in their family to have Brugada syndrome if it has arisen as a new mutation.
Overview
Brugada syndrome (BrS) is a genetic disorder in which the electrical activity of the heart is abnormal. It increases the risk of abnormal heart rhythms and sudden cardiac death. Those affected may have episodes of syncope. The abnormal heart rhythms seen in those with Brugada syndrome often occur at rest. They may be triggered by a fever.
Signs and symptoms
While many of those with Brugada syndrome do not have any symptoms, Brugada syndrome may cause fainting or sudden cardiac death due to serious abnormal heart rhythms such as ventricular fibrillation or polymorphic ventricular tachycardia. Blackouts may be caused by brief abnormal heart rhythms that revert to a normal rhythm spontaneously. If a dangerous heart rhythm does not stop by itself and is left untreated, the person may have a fatal cardiac arrest. However, blackout…
Causes
The individual cells of the heart communicate with each other with electrical signals, and these electrical signals are disrupted in those with Brugada syndrome. As a genetic condition, the syndrome is ultimately caused by changes to a person's DNA, known as genetic mutations. The first mutations described in association with Brugada syndrome were in a gene responsible for a protein or ion channel that controls the flow of sodium ions through the cell membrane of heart mu…
Mechanisms
The abnormal heart rhythms seen in those with Brugada syndrome are typically dangerous arrhythmias such as ventricular fibrillation or polymorphic ventricular tachycardia, but those with BrS are also more likely to experience rapid heart rates due to less dangerous arrhythmias such as AV nodal re-entrant tachycardia and abnormally slow heart rhythms such as sinus node dysfunction. There are …
Diagnosis
Brugada syndrome is diagnosed by identifying characteristic patterns on an electrocardiogram. The pattern seen on the ECG includes ST elevation in leads V1-V3 with a right bundle branch block (RBBB) appearance. There may be evidence of a slowing of electrical conduction within the heart, as shown by a prolonged PR interval. These patterns may be present all the time, but may app…
Treatment
The main aim when treating people with Brugada syndrome is to reduce the risk of sudden death due to serious abnormal heart rhythms such as ventricular fibrillation or polymorphic ventricular tachycardia. While some with this condition are at high risk of serious heart rhythm disturbances, others are at much lower risk, meaning that some may require more intensive treatment tha…
Epidemiology
Between 1 and 30 per 10,000 people are affected by Brugada syndrome. Although those affected are born with the condition, symptoms typically only begin in adulthood. While the rare cases seen in childhood are equally likely to be male or female, in adulthood symptoms occur more frequently in males than females, potentially due to the higher testosterone levels found in men.
Brugada syndrome is more common in people of Asian descent and is the most common cause …
History
Brugada syndrome is named after the Spanish cardiologists Josep and Pedro Brugada who described the condition in 1992, although the association between the characteristic ECG pattern and sudden cardiac death had been reported in 1989. Brugada syndrome was described as a cause for the sudden unexplained cardiac death syndrome seen in Thai men in 1997. The first genetic mutations affecting the SCN5A gene associated with the syndrome were identified by th…
