背　景 近年來隨著資訊與電腦科技的日益進步，多媒體教學也逐漸受到護理教育界之重視。多媒體教學不但可以打破時間與空間的限制，也可以提供更生動活潑的學習環境，使學習者能更方便且容易學習，進而提高學習成效。
目　的 本研究以心電圖學為主題，應用多媒體技術研發一套教學輔助教材，並將其介入於臨床護理人員在職教育中，以探討心電圖知識之學習成效。
方　法 本研究採準實驗性前後測研究設計，以立意取樣，選取台北市某醫學中心加護單位護理人員共77人進行施測。於「心電圖多媒體教學課程」介入之前後，以「心電圖教學之知識量表」收集相關資料。
研究資料以SPSS 15.0 Window套裝軟體進行各項統計分析。
結　果 本研究結果顯示：⑴教學介入後，實驗組在心電圖知識得分顯著優於對照組。⑵教學介入後，實驗組在心電圖知識後測得分能顯著提升。
結　論／實務應用 依本研究結果建議未來安排護理人員繼續教育時可運用多媒體教學策略，以增加護理人員學習興趣與動機，並提高學習成效。

Background: Rapid enhancements in information technology have focused increasing attention on the potentials of multimedia-assisted instruction in nursing education. Multimedia-assisted instruction not only goes beyond con-straints on time and space, it further provides learners with a more active and dynamic environments for learning. In this context, learning becomes easier and more convenient. Most importantly, such instruction has been shown to en-hance the effectiveness of student learning.
Purpose: The purpose of this research was to develop multimedia-assisted teaching materials focused on the subject of electrocardiography and to discuss the resulting effcacy of electrocardiography education relative to the overall in-service nursing education curriculum.
Methods: This study employed a pretest-posttest quasi-experimental design method and purposive sampling. Seven-ty-seven nurses were enrolled as participants from intensive care units of a Taipei hospital. An EKG knowledge ques-tionnaire was employed to collect data once prior to the start of the course and once following course completion. Data were analyzed using the SPSS 15.0 for Windows software package.
Results: Results showed the experimental group scored signifcantly higher on ECG knowledge after the intervention than the control group. The experimental group further showed signifcant differences in ECG knowledge in terms of pre- and post-intervention measurements.
Conclusions / Implications for Practice: In the future, the strategy of multimedia-assisted instruction should be applied extensively in the nursing staff continuing education curriculum in order to increase learner interest and moti-vation.
