Transcript of Brugada syndrome
What is Brugada Syndrome?
Brugada Syndrome is a life threatening frequently inherited disorder characterized by an abnormal heart rhythm.
This arrhythmia prevents the chambers of the heart from pumping effectively, preventing blood from traveling normally throughout the body.
What are the symptoms?
Many who have Brugada Syndrome go undiagnosed because the condition sometimes does not cause any noticeable symptoms.
But some possible signs are fainting, irregular heartbeat or heart palpitations and sudden cardiac arrest.
One of the most important signs of Brugada Syndrome is an abnormal pattern on a ECG called a type 1. Brugada Syndrome cant be felt and is only detected on a ECG.
How Common is Brugada Syndrome?
The exact prevalence of Brugada Syndrome is unknown, although it is estimated to affect 5 in 10,000 people worldwide. This condition occurs much more frequently in people of asian ancestry, Particularly in Japanese and Southeast Asia populations. It affects both men and women but more frequently found in men. Researchers suspect that a sex hormone present at a much higher level in men may be responsible.
What are the causes?
Each beat of your heart is triggered by an electrical impulse generated by special cells in the right upper chamber of your heart. Tiny pores called channels on each of these cells direct this electrical activity which makes your heart beat.
In Brugada syndrome, a defect in these channels can cause your heart to beat abnormally and spin electrically out of control in an abnormally fast and dangerous rhythm.
As a result, your heart doesn't pump effectively and not enough blood travels to the rest of your body.
Test & Diagnosis
How it is Inherited
Brugada Syndrome is usually an inherited condition which means its passed down through family members. Research shows that in about one-third of patients, doctors know which medical gene is responsible for the condition.
There is no know cure, The only proven effective treatment is the implantation of an implantable cardioverter defibrillator.
This device automatically senses when the heart experiences a dangerous arrhythmia and automatically provides an electrical shock to restore normal sinus rhythm.
If your doctors may think you have Brugada Syndrome they may order:
Electrocardiogram which helps doctors analyze the electrical currents in your heart and the patterns of your heartbeat.
Which is given after test have shown that you do have Brugada Syndrome.
a long, thin tube called a catheter is inserted into an artery in your leg and guided to your heart. A map of electrical impulses from your heart is sent through the catheter. This map helps doctors find out what kind of arrhythmia you have and where it starts.
What are the risk factors?
Risk factors for Brugada syndrome include:
Family history of Brugada syndrome
:If other family members have had Brugada syndrome, you're at an increased risk of having the condition.
• Being male:
Adult men are more frequently diagnosed than are women. In young children and adolescents, however, boys and girls are diagnosed at about the same rate.
Brugada syndrome occurs more frequently in Asians than in other races.
While having a fever doesn't cause Brugada syndrome by itself, fever can irritate the heart and stimulate a Brugada-triggered faint or sudden cardiac arrest, especially in children.
