How does Brugada syndrome affect the heart?
How does Brugada syndrome affect the heart?
Brugada syndrome is a rare but serious condition that affects the way electrical signals pass through the heart. It can cause the heart to beat dangerously fast. These unusually fast heartbeats – known as an arrhythmia – can sometimes be life threatening.
Does Brugada cause bradycardia?
Background: In patients with Brugada syndrome (BS), ventricular fibrillation (VF) occurs mainly during sleep; therefore, not only vagal activity but also bradycardia dependent changes in ECG may relate to the nighttime occurrence of VF.
What does Brugada syndrome do to Your Heart?
Brugada syndrome is a genetic disorder that can cause a dangerous irregular heartbeat. When this happens, the lower chambers of your heart (ventricles) beat fast and irregularly. This prevents blood from circulating correctly in your body.
Can a person with Brugada syndrome have a blackout?
Signs and symptoms. If a dangerous heart rhythm does not stop by itself and is left untreated, the person may have a fatal cardiac arrest. However, blackouts can occur in those with Brugada syndrome despite a normal heart rhythm due to a sudden drop in blood pressure, known as vasovagal syncope.
How did Brugada syndrome get its name?
Brugada syndrome is named after the Spanish cardiologists Pedro and Josep Brugada who described the condition in 1992, although the association between the characteristic ECG pattern and sudden cardiac death had been reported in 1989.
How are defibrillators used to treat Brugada syndrome?
In some patients, an implanted cardioverter defibrillator can help prevent sudden death related to Brugada syndrome. When this device detects the start of an arrhythmia, it sends out one or more brief shocks to your heart to reset it back into its regular rhythm.
What happens to the heart with Brugada syndrome?
Collapse Section Brugada syndrome is a condition that causes a disruption of the heart’s normal rhythm. Specifically, this disorder can lead to irregular heartbeats in the heart’s lower chambers (ventricles), which is an abnormality called ventricular arrhythmia.

Is the Brugada syndrome the same as Sunds?
This condition was originally described in Southeast Asian populations, where it is a major cause of death. Researchers have determined that SUNDS and Brugada syndrome are the same disorder. The exact prevalence of Brugada syndrome is unknown, although it is estimated to affect 5 in 10,000 people worldwide.
