Pediatric Electrocardiography Interpretation: Where We Are Now?

Electrocardiography (ECG) is an important diagnostic tool used in the early diagnosis and treatment of arrhythmias and conduction disorders. Pediatricians need to interpret the ECGs correctly and be able to decide the situations that require pediatric cardiology consultation. In this study, we aimed to determine the ECG evaluation competencies of pediatricians. The obtained data will serve as a guide for the development of a training module.

Pediatric residents and specialists were included in the study. A questionnaire was sent to the participants via Google Forms. In this questionnaire, participants were asked to evaluate whether 10 ECG samples were normal or abnormal, detect the abnormality in the ECGs, define the specific diagnosis, and indicate how confident they were in their evaluation. A total of 242 participants, 160 of whom were pediatric residents and 82 were pediatricians, were included in the study.

The mean knowledge level of the participants was 17 ± 4.1 out of 30 points. Electrocardiography knowledge score increased with increasing age, increasing experience after graduation from medical school, increasing seniority during residency training, and increasing self-confidence in ECG interpretation. A significant difference was found between the ECG knowledge scores of those who attended an ECG course after graduation and those who did not. The rate of correctly defining the distinction between normal and abnormal was 93.7%. The rate of detecting pathologies in ECGs accurately and correct identification of specific diagnosis was 56.7%.

The accuracy level of pediatricians in ECG evaluation is low. Electrocardiography trainings are needed to develop ECG assessment skills.
