"Child Nearly Dies After Taking Big Bite of Hot Dog"

The Brugada Syndrome

Last month, several news outlets sensationalized an event that probably struck fear in the minds of parents concerning the deadly consequences of the all American Hot Dog.

  • “Boy takes bite of hot dog and his heart stops” – CNN
  • “Child Nearly Dies After Taking Big Bite of Hot Dog” – livescience
  • “Bite of hot dog stops 9-year-old boy’s heart, reveals Brugada syndrome” – USAToday

The last headline gives a clue of the unusual underlying condition, the Brugada Syndrome, and the article describes the scene as “the boy was eating a hot dog and he fainted”.

After resuscitation, Turkish physicians determined that the vagus nerve, the nerve that can affect the heart rate, was stimulated and slowed his heart rate down and caused him to go into cardiac arrest.

What is the Brugada Syndrome?

The Brugada Syndrome, first described in 1992 by the Spanish cardiologists Pedro Brugada (de), Josep Brugada and Ramon Brugada, is a genetic condition that affects the specialized conduction system of the heart. Specifically, it may cause ventricular tachycardia due to abnormalities in the sodium ion channels in the conduction system. Abnormalities that affect the rhythm and the contraction of the heart.

It is suggested that there are some structural differences in the normal conduction system as seen in this image highlighting the left and right bundle branches.

The detection of Brugada Syndrome is usually determined after an event by employing electrocardiography. Since it is a genetic disorder, most physicians will test other family members as a precaution.

The Specialized Conduction System

The specialized conduction system of the heart consists of nerve tissue that initiates and transmits the electrical impulse for cardiac muscle cells to contract.

The normal action potentials of the heart follow a particular series of events that occur in the stimulation of the myocardium to contract. The exchange of sodium, potassium, and calcium across the cell membrane is required for contraction. The typical action potential of the heart muscle creates a waveform which consists of 4 phases.

In Brugada Syndrome, the action potentials of many cells are not in sync and can trigger cardiac arrhythmias.

The profile of the transmural action potentials vary from the norm due to aberrations sodium ion exchange.

The Electrocardiogram

The syndrome is also classified into 3 categories based on the electrocardiogram, they are:

  • Brugada Type I – Coved ST-segment elevation, high J-point amplitude ≥ 2mm, and a negative T wave
  • Brugada Type II – J-point elevation ≥ 2mm, saddleback ST-segment, positive or biphasic T-wave
  • Brugada Type III - Saddleback or coved with St-segment elevation < 1mm, T-wave not as marked

Special Procedures - The Drug Challenge

Under controlled and monitored setting, medications like procainamide or flecanide may be used to observe changes in the electrocardiogram indicating the effects in changing the ionic balance of the conduction system.

Things To Look Out For In Brugada Syndrome

Signs and Symptoms

Similar to most cardiac emergencies, the Brugada Syndrome includes:

  • Palpitations
  • Syncope
  • Seizures
  • Sudden death


There are no cures for Brugada Syndrome but treatment methods may include channel blocking agents to minimize abnormal rhythms or an implantable cardiac defibrillator in high-risk patients.


Genetic testing is a trend in heart diseases that may have a familial or genetic origin. The identifications of certain genes may identify the possibility that a patient is at high risk and follow-ups are usually performed for the signs of progression at which an appropriate treatment may be planned.

So, despite the headlines, hot dogs are not to blame for cardiac arrest, however, due to the high levels of bad fats in these tubes of deliciousness, one should eat them only sparingly as part of a healthy diet.
