Kawasaki disease electrocardiogram

Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Dildar Hussain, MBBS [2]

Overview

Electrocardiogram in Kawasaki disease may demonstrate evidence of ventricular dysfunction or, occasionally arrhythmia due to myocarditis. However, in acute disease the electrocardiogram may demonstrate prolonged PR interval, non-specific ST changes, T-wave changes and increased Q/R ratio, which are consistent with myocarditis.

Electrocardiogram in Kawasaki disease may demonstrate evidence of:^[1]
- Ventricular dysfunction
- Arrhythmia due to myocarditis
In the acute phase, the electrocardiogram may demonstrate the following abnormalities consistent with myocarditis:^[2]^[3]
- Prolonged PR interval
- Nonspecific ST changes
- T-wave changes
- Increased Q/R ratio
