Aim: The aim of the study was to evaluate ECG interpretation skills among study population, and analyze factors determining their score.
Introduction: The electrocardiogram examination is one of the most frequently performed diagnostic test. Correct interpretation of the ECG, particularly in life-threatening scenarios (LTS) may influence the decisions on appropriate actions and consequently have an impact on the lives and health of patients. It is important for medical, nursing and emergency medicine students to acquire this skill.
Methods: ECG interpretation skills were assessed by self-prepared questionnaire including questions about demographic data and 20 ECG problems with 17 cases. In 6 cases there were LTS. Three questions evaluated basic knowledge about rhythm, heart rate and axis. The survey was conducted via Internet. Study population consist of 551 medical, nursing and emergency medicine students.
Results: The overall score among Polish medical students is 46% which is higher than nursing and emergency medicine students (22% and 37% respectively; p<0.001 in both). English division students scored almost similarly (49%; p=0.27). Polish medical students scored better in LTS than the nursing students (37% vs 23%; p<0.001). Among Polish medical students: Students in year “4–6” scored higher than those from year “1–3” (overall score: 51% vs. 31%; p<0.001, LTS: 41% vs 25%; p<0,001). In addition, members of cardiology scientific groups scored higher than the rest (57% vs 43%; p<0.001).
Conclusion: There is low level of ECG interpretation among medical students and quality of ECG training should be improved. Various factors influences ECG interpretation knowledge among students.
