Introduction
Electrocardiography is the most commonly used diagnostic test in cardiology. If properly
interpreted, it contributes significantly to the diagnosis and management of patients with cardiac
disorders. Importantly, it is essential to the diagnosis of cardiac arrhythmias and the acute
myocardial ischemic syndromes. These two conditions account for the majority of cardiac
catastrophes. It is appropriately used as a screening test in many circumstances.1 Basic knowledge
of the ECG is usually the most difficult to assimilate, as it implies learning the basis of
interpretation. With technological advances, changes in provision of healthcare services and
increasing pressure on critical care services, ward patients' severity of illness is ever increasing. As
such, nurses need to develop their skills and knowledge to care for their client group. Competency
in cardiac rhythm monitoring is beneficial to identify changes in cardiac status, assess response to
treatment, diagnosis and post-surgical monitoring.2 Every nursing student, nurse or even resident
doctor must be aware of the importance of correlating clinical findings after a complete
examination with the ECG finding. A good basic ECG interpretation may rely on the ability to
combine clinical skills with basic ECG interpretation.
6.1 The need for the study
Understanding and interpreting a standard 12-lead ECG can prove to be a quite difficult
task, especially for nursing students and practicing nurses at their first contact with clinical cases
requiring an accurate interpretation of an ECG. Interpretive exercises are identified as one of the
best methods to measure complex achievements by many educationist3. The students admitted to
third year B. Sc. Nursing programme have to study Advanced Medical-Surgical Nursing in their

curriculum, which highlights the need to have an in-depth understanding of the various diagnostic
tests. This study will help the students to obtain an understanding of the interpretation of ECG
changes of selected cardiac conditions, which will in turn help them to fulfil the needs of a
practicing nurse in the future. The graduate nurses has a large area of scope in nursing practice by
taking up the roles such as case manager, nurse practitioners, nurse managers etc. The
performance of these upcoming roles necessitates the need for learning the interpretation of ECG
changes.
A comparative study was conducted to investigate nursing students' responses to a basic
electrocardiography by a computer assisted learning (CAL) programme and a lecture on the same
topic. There were no significant differences between the CAL and lecture groups on cognitive
outcomes (measured by a 20 item test on electrocardiogram knowledge) or transfer of learning
outcomes (measured in the clinical setting by the students' ability to identify and interpret six
electrocardiogram tracings). However, CAL students displayed more positive affective responses.
They also took between 10 and 32 minutes to complete the programme while all lecture students
took a mandatory 50 minutes or more4.
A comparative study was conducted to assess the long term results of the pedagogic
approach (self instructional module). Fifth year medical students were assigned to receive self
instruction modules or expositive lectures on electrocardiography. The knowledge and opinions of
these two groups were evaluated two years later. Knowledge assessment was significantly better
among students receiving self instruction modules The self instruction method and traditional
lectures were qualified as very useful by 86.8 and 38.9% of students respectively. It is concluded
that self instruction methods have good long term results, when applied to medical students5.

From the above descriptions and personal experiences while working as a staff nurse in
cardiology department, the researcher felt a need to conduct a study to determine the effectiveness
of self instructional module on ECG interpretation of selected cardiac conditions for 3rd year B. Sc.
Nursing students with the main objective of improving their knowledge.
6.2 Review of Literature
A study conducted in 2004 to examine the effect of web based teaching method on
undergraduate nursing student’s of electrocardiography.. The study used a pre-test post-test
experimental design. A total of 105 senior nursing students were recruited at a university in Korea.
In that 54 students were assigned to an experimental group & 57 were assigned to a control group.
Knowledge about ECG among students in the control group was significantly lower than that of
students in study group (p<0.01) conversely the ability to interpret ECG recording was
significantly higher among students in the web based group (p<0.05). No significant difference
found between the two groups in level of motivation or satisfaction with learning. The self directed
web based ECG learning programme appears to be effective in helping nursing students to
interpret ECG recording.6
An exploratory study was conducted to determine, whether the ward nurses have basic
knowledge regarding 12 lead ECG recording and their interpretation ability in ECG changes
among nurses in general ward areas. The nurses were instructed to complete a 14 item
questionnaire on basic 12 lead ECG knowledge. The results of completed questionnaire by staff
nurses revealed that overall knowledge was insufficient. The mean score for correct answer was
42% those who had attended education session scored 55%. In that 79% of all nurses surveyed to
4
![Page 5: 05_N013_13909](https://reader036.vdocument.in/reader036/viewer/2022082419/544c4382b1af9f6e7d8b49dd/html5/thumbnails/5.jpg)
perform ECG on their wards. The reason given for performing the majority of ECGs were chest
pain and pre-operatively. Other reasons included pulmonary embolism, irregular pulse, post
cardiac catheter and angioplasty. In that 39% of ECGs were reviewed immediately 35% in 1-2
hour, 4% in 3-4 hrs, 9% at > 4 hrs, and 13% never.7
An evaluatory study was conducted to assess the effectiveness of a competency programme
on ECG interpretation and monitoring & also to find out the competency of staff nurses working in
critical care areas and to determine the factors influencing their competency as expressed by them.
A teaching guide on ECG monitoring and interpretation was prepared and distributed among the
participants. Descriptive and inferential statistics were used to analyze the data. The significant
findings of the study were: majority 29 (96.66%) of were having general nursing and midwifery
degree. Most 6 (20%) were from paediatric ICU and most of the staff nurses were having >7 years
of experience in critical care area. Statistical analysis shows that there was a significant increase in
competency scores (t29 = 8.11, p<0.05). Area-wise competency analysis shows that there was a
significant increase in knowledge (t29=9.35 p<0.05) and skill (t29=4.78, p<0.05) scores but there
were very minimal increase in attitude scores.8
A comparative study was conducted to determine the knowledge retention after completion
of either a competency based written self instructional module or a competency based didactic
lecture module among registered nurses. The 67 subjects were given pre-test and the same content
material using the two types of presentations and the post-test. Results indicated that no significant
difference among post-test scores of the treatment group and the control group. Knowledge
retention essentially was the same, regardless of the antecedent teaching methodology. The
advantage of one teaching method versus another may be in the flexibility afforded by the staff
5

educator. After desired outcomes are identified, a teaching method can be determined based on the
staff educator’s requirements, the resource available & the learner’s need9.
An experimental study was conducted to compare the effectiveness of assisted self-directed
learning (ASD) and traditional lecture method (TLM) in acquiring competency for
electrocardiogram interpretation, within a conceptual framework of developmental and adult
learning theory. After two teaching units were designed and an EKG post-test was constructed (r
=0.75) from actual patient records, registered nurse volunteers (N=19) were randomly assigned to
groups for simultaneous instruction. Because of the small sample size, statistical procedures were
used to determine the effectiveness of randomization and to justify statistical procedures. EKG
post-test scores for the experimental group (ASD, M=81) and the control group (TLM, M=71)
were significantly different. ASD had higher mean score and is more cost and time efficient.10
An evaluatory study was conducted to find out the effectiveness of computer-based tutorial
and a post-test on ECG interpretation for training residents and determining competency :forty
residents, six cardiology fellows, and four experienced physicians participated. The tutorial
emphasized recognition and understanding of abnormal ECG features. Active learning was
promoted by asking questions prior to the discussion of ECGs. Interactivity was facilitated by
providing rapid and in-depth rationale for correct answers. Post-test grades revealed that the
tutorial, contributed to marked improvement in feature recognition. Competency testing
distinguished between residents with outstanding grades and those who needed remediation. The
strategy for critical evaluation of our computer programme could be applied to any computer-
based educational programme, regardless of the topic.11
