The
Process
"A WebQuest is an inquiry-oriented activity in
which most or all of the information used by learners is drawn from
the Web"
- Bernie Dodge accessed September 22. 2006 from
http://webquest.sdsu.edu/overview.htm.
You will explore the content for this WebQuest by following the
provided links to access information about Cardiac arrhythmias.
You can work in groups or independently.
1. First you will need to review the anatomy and physiology of the
heart. You can access information related to the Anatomy & Physiology
of the heart by using your university textbooks or through the various
links, including:
http://www.gwc.maricopa.edu/class/bio202/Cardiovascular/models/hartint0.htm
http://www.hhmi.org/biointeractive/cardiovascular/animations.html
Click on Banjo Man to view a short video reviewing the A&P of the
heart.http://www.youtube.com/watch?v=PIyHkONpH40
2. Next, you will need to review the conduction system of the heart.
Again, you can access information related to the cardiac conduction
system by using your university textbooks or through the various
links, including:
http://www.hrsonline.org/PatientInfo/TheNormalHeart/
3. After you have reviewed the conduction system of the heart, you
will need to determine how to identify the various components of
a normal electrocardiogram (ECG) pattern and how those components
are related to the conduction system. (Remember an ECG is simply
the graphic representation of the electrical conduction of the heart.)

ECG Interpretation
4. Finally, you will explore the various cardiac rhythms based upon
their point of origin:
- Sinus Rhythms
- Atrial Rhythms
- Nodal rhythms/Heart
Blocks
- Ventricular
Rhythms
*Important items to note are rhythm regularity, heart rate, presence
and characteristics of P-waves, P-R interval duration, presence
and characteristics of QRS complex, and QRS duration.
This lesson
is presented as an independent learning activity to supplement the
Cardiac Module presented to sophomore nursing students. It is made
available to the learner one week prior to the beginning of didactic
portion of the cardiac content. The learner is given two weeks to
complete the activity on their own time. During those two weeks,
the cardiac didactic content will be provided to the learner.
The learner can choose to do the WebQuest alone or as a group. For
group work, all members will receive one group grade. Collaboration
is encouraged.
The teacher should possess a solid knowledge of the content provided
in the WebQuest. It is imperative that suggested links have been
assessed for content validity and reliability.
