Brugada syndrome is a serious heart disease with a genetic basis that appears as one of the cardiac arrhythmias. This syndrome arises due to abnormalities in the electrical conduction system of the heart and can increase the risk of sudden cardiac arrest, especially in young adults. Symptoms may include dizziness, shortness of breath, palpitations, and arrhythmia. However, symptoms can vary from person to person and may sometimes be asymptomatic. Treatment is generally determined based on the symptoms, the patient's general health status, and risk factors.
Brugada syndrome is a disease that can be identified with genetic tests and controlled with early diagnosis. Therefore, it is important for individuals carrying risk factors to protect their health through regular cardiological check-ups and genetic tests.
What Are the Symptoms of Brugada Syndrome?
Brugada symptoms usually occur due to cardiac arrhythmia and can vary from person to person. The symptoms of this syndrome are generally mild and sometimes may not present any symptoms at all. However, when symptoms are observed, it is important to consult a specialist cardiologist immediately. Here are the symptoms of Brugada syndrome:
Dizziness and Fainting: In cases where blood cannot be pumped sufficiently due to cardiac arrhythmia, dizziness and fainting spells may occur. These symptoms usually appear suddenly.
Shortness of Breath: As a result of the heart working irregularly, sufficient oxygen cannot be transported to the body, which can cause shortness of breath. Shortness of breath can especially occur during sleep at night.
Sudden Heartbeat Changes: In individuals with Brugada syndrome, sudden increases or decreases in heartbeats can be observed. This condition may be a sign of cardiac arrhythmia.
Family History: Since Brugada syndrome is a genetic disease, having similar conditions in the family history can also be a symptom. If there are sudden deaths or heart problems in the family, genetic tests may be recommended in this case.
What Causes Brugada Syndrome?
Brugada syndrome is a condition usually based on genetic factors and causes cardiac arrhythmia. However, there may be various causes that influence the emergence of this syndrome. Here are the main factors contributing to the development of Brugada syndrome:
Genetic Factors: Brugada syndrome usually occurs due to certain genetic mutations. These mutations can disrupt the normal electrical conduction of heart cells, leading to arrhythmia.
Drug Use: Certain medications can trigger Brugada syndrome. Antiarrhythmic drugs, which have an effect on heart rhythm in particular, have the potential to bring out this syndrome. Additionally, some antidepressants and antipsychotic medications can also be a risk factor.
Substance Use: Illicit substances, especially stimulants such as cocaine and ecstasy, can trigger Brugada syndrome. These substances can increase the risk by causing cardiac arrhythmia.
Electrolyte Imbalances: Electrolyte imbalances in the body, especially low potassium levels, can affect Brugada syndrome. Potassium is important for the normal conduction of heart cells.
Ischemia (Lack of Blood Supply): Situations where the heart cannot receive enough oxygen are called ischemia. Ischemia can contribute to the triggering of Brugada syndrome.
Heart Failure: Heart failure is a condition where the heart cannot perform its normal pumping function. This situation can pave the way for Brugada syndrome.
Who Gets Brugada Syndrome?
Brugada syndrome is a cardiac arrhythmia based on genetic mutations and is generally seen more frequently in males, young adults, particularly individuals of Asian descent, and people who have experienced this syndrome in their families. Patients generally experience symptoms such as dizziness, shortness of breath, racing heart, arrhythmia, and sudden fainting spells.
A family history of sudden death, a distinct ECG pattern, and other heart problems can increase the risk of Brugada syndrome. Genetic tests are important in diagnosis. Factors such as substance use, medications, electrolyte imbalances, and ischemia can also influence the emergence of the syndrome.
Brugada Syndrome Treatment
Brugada syndrome treatment is personalized according to the patient's symptoms and risk factors. Drug therapy aims to keep seizures under control by regulating the heart rhythm. Catheter ablation can be considered in patients who are not suitable for or do not respond to medications. In this procedure, abnormal electrical activity is corrected using radiofrequency energy.
The use of an implantable cardioverter-defibrillator (ICD) is considered in high-risk patients, and the ICD protects vital functions by sending automatic shocks in the event of cardiac arrest. It is important for patients to control risk factors and avoid smoking and alcohol.
Regular doctor check-ups and follow-ups are important to evaluate the effectiveness of the treatment and monitor the patient's condition. The treatment process should be tailored to the patient's individual needs and guided by a specialist cardiologist.
