Transient sinus node dysfunction with acute hepatitis of unknown etiology.

Area of Science:

• Cardiology
• Hepatology
• Electrophysiology

Background:

• Atrioventricular block and atrial arrhythmia are significant cardiac conditions.
• Hepatitis, an inflammation of the liver, can have systemic effects.
• The relationship between hepatitis and cardiac arrhythmias requires further investigation.

Observation:

• A 72-year-old diabetic male presented with complete atrioventricular block.
• During acute hepatitis, he developed transient atrial arrhythmia and sinus node dysfunction.
• Cardiac investigations including electrocardiogram, echocardiography, and thalium stress test were normal.

Findings:

• The patient's cardiac symptoms resolved completely following the improvement of hepatitis.
• Follow-up Holter monitoring at 3 and 6 months showed no recurrence of arrhythmia.
• Literature review explored the association between hepatitis and atrial arrhythmia.

Implications:

• This case suggests a potential transient link between acute hepatitis and cardiac arrhythmias.
• Hepatitis may precipitate or unmask underlying cardiac electrical instability.
• Further research is warranted to elucidate the mechanisms connecting liver inflammation and cardiac arrhythmias.
