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:

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.)

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.
