Catastrophic neurologic syndrome with dramatic ECG changes.

Area of Science:

• Neurology
• Cardiology
• Critical Care Medicine

Background:

• Cerebrogenic electrocardiogram (ECG) abnormalities, such as T wave inversions and QT interval prolongation, are recognized complications of neurological injury.
• Various arrhythmias, including ventricular tachycardia (VT), can occur following neurologic insults.

Observation:

• A 22-year-old male presented with idiopathic acute encephalopathy, characterized by persistent fevers and refractory seizures managed with propofol.
• Serial ECG monitoring revealed significant ventricular repolarization abnormalities.

Findings:

• The patient exhibited marked QT(U) interval prolongation with episodes of torsade de pointes (a form of polymorphic VT).
• Diffuse ST elevations mimicking myocardial infarction and a Brugada-like pattern were also observed.
• This constellation of ECG findings is unprecedented in the context of a severe neurologic syndrome.

Implications:

• This case underscores the potential for profound and diverse cardiac manifestations secondary to acute encephalopathy.
• The findings suggest a need for comprehensive cardiac monitoring in patients with severe neurological conditions.
• Further research is warranted to elucidate the mechanisms linking catastrophic neurologic events to complex ECG abnormalities.
