Electrocardiographic changes after recovery from measles.

Children with measles seen at our hospital had an initial electrocardiogram (ECG) and a repeat after 3 months. The patients were aged 5 months to 8 years (mean 19 months). The ECG changes observed after clinical recovery included T-wave inversion in eight patients (16%), flattening in eight patients (16%), prolonged PR interval in six (12%), prolonged Q-Tc in three (6%) and low QRS amplitude in four (8%). At least one ECG change was present in 18 patients (36%) after recovery, 14 of these were due to persistence of the changes noted during measles. The implication of above findings and the need for a longer-term follow-up study are discussed.
