Medical Students' Competency and Confidence in Interpreting Electrocardiograms at King Faisal University, Al-Ahsa.

ABSTRACT

Introduction Electrocardiography is a crucial emergency tool in the pre-hospital situation. It is a useful non-invasive diagnostic technique for quickly identifying various heart disorders. The clinical value of the electrocardiogram (ECG) depends on the clinician's ability to interpret the result of the ECG accurately. Aims This study aims to assess the competency as well as the confidence in the interpretation of ECG among medical students at King Faisal University, Al Ahsa, Saudi Arabia. Methods This cross-sectional study was conducted among medical students enrolled at King Faisal University. Four hundred and ten (410) medical students from all five years completed an electronic self-administered pre-validated questionnaire. The questionnaire includes basic demographic data and ECG strips to assess medical students' competency and confidence levels in interpreting each case. Results More than half of the medical students were considered to have low competency (56.1%) and confidence (59%) levels. Increased competency and confidence scores were associated with fifth-year medical students and those who learned more about ECG interpretation through teaching during clinical rotations. The majority of medical students correctly interpreted anterior MI (69.3%), ventricular tachycardia (65.6%), and supraventricular tachycardia (61.2%). On the other hand, most students were unable to correctly identify pacemaker ECG (19.8%), long QT (21.2%) and left bundle branch block (33.4%). Conclusion Medical students' competency and confidence in ECG interpretation seems to be lacking. Fifth-year medical students who learned more ECG skills through teaching during clinical rotations tended to be more competent and confident with their ECG interpretation skills.
