Abstract

The electrocardiogram (ECG) is the most widely used cardiovascular diagnostic test and its interpretation depends on the physician's knowledge.


Objective: To evaluate the knowledge of ECG interpretation and its associated factors in medical students during their medical internship at a Peruvian university.


Methods: This is an observational, analytical and cross-sectional study. The sample consisted of 148 medical students evaluated by means of the "Electrocardiography Knowledge Questionnaire".


Results: 53.38% (n=79) of the medical interns had a medium level of knowledge of ECG interpretation, 43.25% (n=64) a high level and 3.37% (n=5) a low level. In the bivariate analysis, the statistically significant factors associated with knowledge were: weighted grade point average p=0.000; PR=1.285; 95%CI [1.158-1.426], having taken the Critical Patient Management course p=0.019; PR=1.148; 95%CI [1.025-1.286], orientation towards a medical specialty p=0.033; PR=0.881; 95%CI [0.785 -0.989]. In the multivariate analysis, the statistically significant factors were: weighted average of "Good" ratings p=0.000; PR=4.738; 95%CI [2.216-10.133] and orientation to a clinical specialty p=0.025; PR=2.382; 95%CI [1.114-5.094].


Conclusions: final year medical students predominantly present a medium and high level of knowledge of ECG interpretation and the significantly associated factors were: having a weighted grade point average in the good category, having taken the Critical Patient Management course, and having an orientation towards a clinical specialty.
