Aim: The aim of this study was to compare cardiac physiology practices which were applied on the frog heart with watching the video of the same experiment by the first year medical students.
Methods: Students (n=217) observed an experimental study on frog heart and they prepared an observation report at the end of this practice. Other students (n=196) watched the video recordings of the same experiment. They also prepared an observation report. Grades were given from the reports. All students were answered a Likert type questionnaire about what they learnt one year after the practice. The answers were compared in two groups by Mann Whitney U test and Chi-squire test.
Results: No difference was determined between the answers about to understand the cardiac function (p=0.980), the effects of ions on cardiac function (p=0.709), knowledge about pace makers and conduction system of the heart (p=0,474) in two groups. Grades were higher for the students who were watched the video recordings than the students who were observed the animal study (88,4 and 84,7 out of 100, respectively, p<0,01).
Conclusions: The present study demonstrated that watching video recordings are suitable alternative instead of using living animals in teaching cardiac physiology.
