Insights
Sudden infant death in a neonate was linked to a Brugada ECG pattern, later attributed to medium-chain acyl-CoA dehydrogenase deficiency. This suggests fatty acid buildup may trigger the Brugada pattern.
Area of Science:
- Neonatal cardiology
- Metabolic disorders
- Clinical electrocardiology
Background:
- Brugada syndrome is a rare genetic disorder characterized by abnormal electrocardiogram (ECG) findings and an increased risk of sudden cardiac death.
- Fatty acid oxidation disorders (FAODs) are inherited metabolic diseases that impair the body's ability to break down fatty acids for energy.
Observation:
- A neonate resuscitated from sudden death presented with a Brugada electrocardiogram (ECG) pattern days after the initial event.
- The neonate was diagnosed with medium-chain acyl-CoA dehydrogenase deficiency (MCAD), a type of fatty acid oxidation disorder.
Findings:
- The study reports a correlation between medium-chain acyl-CoA dehydrogenase deficiency (MCAD) and the Brugada ECG pattern in a neonate.
- This case suggests that the accumulation of free fatty acids, a consequence of MCAD, may induce the Brugada ECG pattern.
Implications:
- This finding may expand the understanding of Brugada syndrome's potential triggers beyond genetic factors.
- Early screening for metabolic disorders like MCAD in neonates with unexplained cardiac events could be considered.
- Further research is warranted to elucidate the precise mechanisms linking fatty acid metabolism and cardiac electrical abnormalities.
Abstract:
We report a neonate resuscitated from sudden death with a Brugada ECG pattern several days after the initial event. The baby was subsequently diagnosed with a fatty acid oxidation disorder (medium chain Acyl-CoA dehydrogenase deficiency or MCAD). We speculate that free fatty acid accumulation can give rise to the Brugada ECG pattern.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

Components of the Electrocardiogram
The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
Cardiac Action Potential
The cardiac action potential process involves a series of phases characterized by the movement of ions across the cardiac cell membranes, leading to the depolarization and repolarization of the cardiac myocytes.
