A Study to Evaluate the Effectiveness of PowerPoint Presentation on Knowledge Regarding Electrocardiogram (ECG) Among Second Year B.Sc. Nursing Students at Selected Nursing Colleges of Udupi, Karnataka

Abstract

ECG is used to measure the rate and regularity of heartbeats, likewise the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart, such as pacemaker. An ECG is the best technique to measure and diagnose abnormal rhythms of the heart, particularly abnormal rhythms caused by damage to the conductive tissue that carries electrical signals, or abnormal rhythms caused by electrolyte imbalances usually for diagnosis of heart abnormalities. Nurses are the primary care givers to the patients so they should have adequate knowledge regarding ECG. A preexperimental research design was used for the present study. The samples are 2nd year B.Sc. nursing students in selected nursing colleges of Udupi districts. Purposive sampling technique was employed to select the participants. The total samples size was 30. The data were collected by using structured knowledge questionnaire. Data collected were that pre- and posttest knowledge analyzed and interpreted by using descriptive and inferential statistics. In the present study it was found that, majority 18(60%) of the students were in the age group of 19 years where as 18(36.66%) were in the age group of 18 years, and 1(3.33%)were more than 20 years, 30(100%) of the students were female, majority 17(56.66%) of the participants belongs to Christian. Where as13(43.33%) were belongs to Hindu, 30(100%)subjects were residing at hostel, majority 23(77.66%) of students were observed ECG procedure, 7(23.33%) of the students were not observed ECG procedure, majority 25(83.33%) of the students’ parents had different occupation, remaining 5(16.66%) were nurses, majority 83.33% of the students were undergone ECG, 16.66% of the students were not undergone ECG procedure. The mean posttest knowledge score (21.6±1.79) was higher than the mean pretest knowledge score (13.13±2.56) and computed ‘t’ value between pre- and posttest knowledge score was (t(29)=2.704, p<0.0495) shows statistically significant in improving the knowledge of the subjects through power point presentation, and there was an association between the pretest knowledge score with the previous observation of the ECG procedure.
