The literature suggests that graduating medical and physician assistant (PA) students lack competency in electrocardiogram (ECG) interpretation. This project aimed to determine whether use of perceptual adaptive learning modules (PALMs) would improve PA students' ECG interpretation, alter self-perceptions of their ECG education, or both.
PALMs were incorporated into the PA curriculum after lecture-based ECG learning. Students' pretest, posttest, and delayed-posttest scores were then compared. Students' ability to correctly interpret ECGs (accuracy) and the percentage of ECGs accurately interpreted within 15 seconds or less (fluency) also were evaluated. Finally, students' perceptions of PALMs and overall ECG training were assessed.
PALM training improved ECG interpretation accuracy and fluency (p < .0001), as well as delayed-posttest accuracy and fluency (p < .0001). The majority of student respondents felt supplemental training enhanced their learning.
These perception results combined with data on ECG interpretation improvement supports continued use of supplemental PALMs in ECG interpretation training.
文献表明，毕业的医学生和医师助理（PA）在心电图（ECG）解读方面缺乏能力。本项目旨在确定使用感知自适应学习模块（PALM）是否会提高 PA 学生的心电图解读能力，改变他们对心电图教育的自我认知，或者两者兼而有之。
在基于讲座的心电图学习之后，将 PALM 纳入 PA 课程。然后比较学生的前测、后测和延迟后测成绩。还评估了学生正确解读心电图的能力（准确性）和在 15 秒或更短时间内准确解读心电图的百分比（流畅性）。最后，评估了学生对 PALM 和整体心电图培训的看法。
PALM 培训提高了心电图解读的准确性和流畅性（p<0.0001），以及延迟后测的准确性和流畅性（p<0.0001）。大多数学生受访者认为补充培训增强了他们的学习。
这些感知结果与心电图解读能力提高的数据相结合，支持在心电图解读培训中继续使用补充 PALM。
