BACKGROUND
Interpretation of electrocardiograms (EKG) is an essential tool for every physician. Despite this, the diagnosis of life-threatening pathology on EKG remains suboptimal in trainees. The purpose of this study is to study resident attitudes and behaviours towards EKGs, and describe an innovative way to teach EKGs.
OBJECTIVE
Study attitudes and behaviours towards EKGs. Describe an innovative way to teach EKGs.
METHODS
Design:
An observational cross-sectional study through an anonymous online survey of resident attitudes and comfort with EKG interpretation. This was followed by creation of a WhatsApp group for discussion and interpretation of EKGs with peers. At the end of the day, the official EKG interpretation was posted.
Setting:
Internal medicine residency at Southern Illinois University.
Participants:
Internal medicine residents
Interventions:
Creation of WhatsApp group to aid with EKG interpretation
Measurements:
A 17 item questionnaire, followed by detection of degree of participation in a WhatsApp group.
RESULTS
Forty-one out of 63 residents (65%) completed the survey. 85% of respondents thought that an interactive way to teach EKGs is the best method of teaching, and 73% did not feel confident interpreting EKGs. 30% often rely on automated EKG interpretation. Further analysis indicated that PGY-1 residents reported ordering fewer EKGs (correlation coefficient -0.399, p = 0.012) and were uncomfortable diagnosing QT prolongation on an EKG (correlation coefficient -0.310, p = 0.049). Residents in the third or greater year of training ordered more EKGs (correlation coefficient 0.379, p = 0.015), less frequently relied on the computer for EKG diagnosis (correlation coefficient 0.399, p = 0.010), and were comfortable diagnosing an acute myocardial infarction and atrial arrhythmias.
CONCLUSIONS
In conclusion, most IM trainees do not feel comfortable interpreting EKG, however, this does improve with PGY year. WhatsApp is a possible platform for teaching EKGs.
