Echocardiography is fundamental in the understanding of cardiology; however, echocardiography is not routinely taught in medical schools. The aim of this study is to assess whether teaching echocardiography to preclinical medical students using an e-learning software (ELS) is practical and appropriate.
From 2017 to 2019, 1084 second-year medical students at Indiana University School of Medicine were introduced to echocardiography by using the ELS. In 2017 and 2018 students had a postcourse survey to assess echocardiography appropriateness and cardiology learning. Students in 2018 and 2019 were assessed for any association between the use of the ELS and learning cardiology by comparing examination scores.
In 2017-2018, 127 students responded to the survey (18% response rate). In 2017, 79% of responders and in 2018, 89% reported that introducing echocardiography to medical students is appropriate. In 2017, 78% and in 2018, 87% reported that it improved the understanding of cardiology. Student ELS usage was high for 2017-2018 (93% and 70%) but dropped in 2019 (30%). In 2018 and 2019, students who used ELS did statistically significantly better on the examination (total scores 84% vs. 82% (P = .008) in 2018; 84% vs. 81% (P = .002) in 2019).
Many 2nd year medical students felt learning echocardiography with ELS was appropriate and enhanced their learning cardiology. Using echocardiography to help learn cardiology appears to be supported with an association of ELS usage and improved examination scores. Our study suggests that echocardiography learning can and probably should begin in medical school.
超声心动图在心脏病学的理解中起着基础性作用；然而，医学院通常不教授超声心动图。本研究旨在评估使用电子学习软件（ELS）向医学预科生教授超声心动图是否实际可行且恰当。
2017 年至 2019 年，印第安纳大学医学院的 1084 名二年级医学生使用 ELS 学习超声心动图。2017 年和 2018 年，学生们通过课后调查评估超声心动图的恰当性和心脏病学学习情况。2018 年和 2019 年的学生通过比较考试成绩，评估 ELS 使用与学习心脏病学之间的任何关联。
2017-2018 年，有 127 名学生对调查做出回应（回应率为 18%）。2017 年，79%的应答者和 2018 年，89%的应答者表示向医学生介绍超声心动图是恰当的。2017 年，78%和 2018 年，87%的应答者表示它提高了对心脏病学的理解。2017-2018 年，学生对 ELS 的使用非常高（93%和 70%），但 2019 年下降（30%）。2018 年和 2019 年，使用 ELS 的学生在考试中的表现显著更好（总分为 84%比 82%（P=.008）在 2018 年；84%比 81%（P=.002）在 2019 年）。
许多二年级医学生认为使用 ELS 学习超声心动图是恰当的，并增强了他们学习心脏病学的能力。使用超声心动图来帮助学习心脏病学似乎得到了 ELS 使用与考试成绩提高之间的关联的支持。我们的研究表明，超声心动图的学习可以并且可能应该在医学院开始。
