Teaching antiarrhythmic therapy and ECG in simulator-based interdisciplinary undergraduate medical education.

Abstract

Third-year students in the Dresden Medical School Programme undergo a 6 week course 'Basics of Drug Therapy' in a problem-based learning curriculum. As part of this course a practical seminar about antiarrhythmic drugs and ECG was set up. This study was conducted to evaluate the use of a simulator in this course. A total of 234 students were randomly allocated to receive instructions with (Group S) or without (Group C [control]) the use of a simulator. After a lecture on antiarrhythmic drugs, arrhythmias were presented to Group S using an advanced life support (ALS) manikin. The students were asked to administer a drug or to defibrillate, and the outcome was shown on the monitor. The students in Group C were presented with ECG charts without a simulator. The course was evaluated by a questionnaire and multiple-choice questions (MCQ) about arrhythmias. We received 222 questionnaires. The content-time ratio was rated almost perfect in both groups, but the students in Group S rated the course better suited to link theory and practice. Students in Group S considered the simulator helpful and a good tool for teaching, and the extra effort to be worthwhile. A significantly higher number of students in Group S preferred electric cardioversion as therapy for ventricular tachycardia. An ALS manikin can be an effective tool in teaching clinical pharmacology.
