[ECG. Chest X ray]

Area of Science:

• Pediatric Cardiology
• Diagnostic Imaging

Background:

• Kawasaki disease (KD) is a pediatric vasculitis with potential cardiac complications.
• Electrocardiogram (ECG) findings in KD are often minimal and dynamic.
• Chest X-rays (CXRs) reveal significant interstitial patterns in most KD cases.

Purpose of the Study:

• To review the spectrum of electrocardiogram (ECG) findings in Kawasaki disease (KD).
• To highlight the diagnostic and prognostic implications of ECG and CXR in KD management.

Main Methods:

• Retrospective analysis of ECG and CXR findings in a cohort of pediatric patients diagnosed with Kawasaki disease.
• Correlation of ECG abnormalities with clinical presentation and coronary artery involvement.

Main Results:

• Common ECG findings include PR prolongation, QTc prolongation, low voltage, ST segment changes, and T wave abnormalities.
• Ischemic changes on ECG can mimic adult patterns when coronary artery lesions are present.
• Chest X-rays frequently show interstitial patterns (90%), with occasional pleural effusion, atelectasis, or emphysema.

Conclusions:

• ECG findings in Kawasaki disease, though often subtle, are important indicators of cardiac involvement and potential complications.
• Integrated analysis of ECG and CXR provides valuable insights into the cardiac status of patients with Kawasaki disease.
