Sudden, unexplained cardiac death, notably during sleep, represents a meaningful but often overlooked public health concern. While relatively rare, certain underlying heart conditions can predispose individuals to fatal arrhythmias without prior warning. This report from Jakarta focuses on Brugada syndrome, a potentially life-threatening heart rhythm disorder characterized by electrical disturbances impacting the heart’s lower chambers, and the importance of recognizing its symptoms and causes for effective risk management.
Jakarta –
Sudden cardiac death during sleep is a frightening prospect for many. Certain heart conditions can trigger abrupt cardiac arrest without any prior symptoms, and recognizing these risks is crucial for public health. One such condition is Brugada syndrome.
Brugada syndrome is a rare but potentially life-threatening heart rhythm disorder that can strike while someone is asleep. Understanding how to detect it, its symptoms, and its underlying causes is vital for those at risk.
What is Brugada Syndrome?
Brugada syndrome is a rare, but potentially fatal, heart rhythm abnormality – a type of arrhythmia. Individuals with Brugada syndrome are at risk of irregular heart rhythms originating in the lower chambers of the heart.

According to Indonesia’s Ministry of Health, the syndrome is diagnosed through an electrocardiogram (EKG). Further testing may include a Holter monitor, which uses a portable EKG to track heart activity for 24 to 48 hours, as well as blood or saliva tests.
What Causes Brugada Syndrome?
Each heartbeat is initiated by electrical signals generated by specialized cells in the right upper chamber of the heart. These cells contain tiny pores, known as channels, that regulate the flow of electrical activity, enabling the heart to beat.
In Brugada syndrome, changes to these channels disrupt the heart’s electrical signals, causing it to beat too quickly and develop a dangerous rhythm. This can prevent the heart from pumping enough blood throughout the body. Brief, irregular heart rhythms can lead to fainting, and in severe cases, sudden cardiac death can occur if the irregular rhythm doesn’t resolve.
The Mayo Clinic reports that Brugada syndrome can be caused by:
- Structural problems with the heart that may be difficult to detect
- Imbalances in chemicals, called electrolytes, that help transmit electrical signals throughout the body
- The use of certain prescription medications or cocaine.
Symptoms of Brugada Syndrome
Often, individuals with Brugada syndrome experience no noticeable symptoms. Sudden cardiac death can occur, particularly during sleep, potentially due to increased tension on the vagus nerve.
However, potential signs and symptoms associated with Brugada syndrome include:
- Dizziness
- Fainting
- Shortness of breath and difficulty breathing, especially at night
- Irregular heartbeat or palpitations
- A very fast and chaotic heartbeat
- Seizures.
