Key result
An asynchronous microlearning ECG curriculum significantly improved Internal Medicine residents' overall ECG interpretation test performance by a mean difference of 0.97 points out of 15.
Why the study?
ECG interpretation skills remain poor among Internal Medicine residents, and there is no standardized method for teaching ECG interpretation.
Does an asynchronous microlearning ECG curriculum improve confidence and skill in interpreting ECGs among Internal Medicine residents?
Does an asynchronous microlearning ECG curriculum improve confidence and skill in interpreting ECGs among Internal Medicine residents?
Mean Difference: 0.97
p-value: p=<0.01
A weekly asynchronous microlearning curriculum significantly improved Internal Medicine residents' confidence and overall performance in ECG interpretation, particularly for identifying normal variants.

May support microlearning ECG curricula in IM residency; hypothesis-generating pending RCTs on retention and outcomes.
Capustin et al. (2025) studied Internal Medicine residents (ECG interpretation skills) (n=151). Asynchronous microlearning ECG curriculum vs. Pre-intervention baseline (internal control) was evaluated on Overall performance on a 15-ECG test (MD 0.97, p=<0.01). An asynchronous microlearning ECG curriculum significantly improved Internal Medicine residents' overall ECG interpretation test performance by a mean difference of 0.97 points out of 15.
