Objectives of the study: To assess effectiveness of demonstration and video assisted teaching on knowledge and practices regarding electrocardiogram among staff nurses. and compare effectiveness of demonstration and video assisted teaching on knowledge and practices regarding electrocardiogram among staff nurses working in the critical care unit.

Method and Materials: Research approach used for the study was quantitative and design was comparative experimental – one group demonstration pretest and posttest and another group video assisted teaching pretest and posttest without control group design was used. Variables under study were demonstration and video assisted teaching and knowledge and practice regarding electrocardiogram. The study was carried out on 60 samples with the Non-probability purposive sampling technique; samples were staff nurses working in the critical unit from selected hospitals of Pune city. Ethical clearance was taken from Institutional ethics committee. The data were directly collected from the staff nurses working in the critical care unit by using structured questionnaire and observation checklist. Tool validity was done to check its consistency & accuracy. Reliability was done and tool found reliable and The pilot study was conducted on sixty samples & the tool was found feasible to conduct study.

Result: The calculated t-value of knowledge score was 18.08 and that of practice was 6.09 statistically found to be significant‘t’ (df = 29) =1.69912 as p<0.05 for knowledge and‘t’ (29) = 1.69912 as p<0.05. The data indicated that demonstration on knowledge and practices regarding electrocardiogram among staff nurses significantly increases the knowledge and practices of staff nurses in posttest. The calculated t-value of knowledge score was 8.5 and that of practice was 5.3 statistically found to be significant‘t’ (df = 29) =1.69912 as p<0.05 for knowledge and‘t’ (df = 29) = 1.69912 as p<0.05. The data indicated that video assisted teaching on knowledge and practices regarding electrocardiogram among staff nurses significantly increased in posttest. The data signified that comparison of the effectiveness of demonstration and video assisted teaching on knowledge regarding electrocardiogram was found to be significant as per t calculated value was 3.6676 at t (df=29) =1.69912 as p<0.05 whereas comparison of the effectiveness of demonstration and video assisted teaching on practice regarding electrocardiogram was found to be not significant as per t calculated value was 0.9564 which was not significant at t (df=29) =1.69912 as p>0.05.

Conclusion: The study finding showed that there was effectiveness of demonstration and video assisted teaching on both knowledge and practices regarding electrocardiogram among the staff nurses working in the critical care unit.
