Ease of Use: 5 stars
Reviewed: Aug 10, 2008 by Health Sciences
Overview: This interactive tutorial reviews the rationale for, and placement of, the
electrodes for the 12-lead ECG. The participant has the opportunity to hear and view correct electrode placement for each lead on a diagram and practice placement. It includes a comparison of lead placement for 12-leads with 5-leads. The tutorial is well-organized, brief, and easy to use. It is appropriate for any individual working in the health care fields who needs to perform ECGs or works with telemetry patients. This tutorial can be used independently. A basic knowledge of the action and electrophysiology of the heart is useful. It is appropriate for use with nurses, allied health technicians, and other who may be responsible for ECG lead placement.
Learning Goals: The following learning objectives are stated: 1. recall human anatomical positioning of ECG electrode placement. 2. compare ECG electrode placement for 5- and 12-lead ECGs. 3. demonstrate ECG electrode placement for a 12-lead ECG. The author does an excellent job of identifying correct positioning of ECG electrodes by anatomical landmarks. Verbal and visual information is provided.
Target Student Population: This tutorial is appropriate for technical and professional students in the health care settings.
Prerequisite Knowledge or Skills: Fundamental knowledge of heart structure, electrophysiology, and ECG equipment would be beneficial prior to completion of this activity. Participants require basic computer literacy for the use of a mouse and the ability to find and install Flash if it is not already loaded on their systems.
Type of Material: The learning resource is classified as a simulation. This activity provides a lecture then
allows the user to simulate electrode placement and provides positive feedback for correct placement.
Recommended Uses: This activity could be used as an in-class activity but would be particularly useful as a supplemental or self-directed learning activity. Given that participants simulate electrode placement it would nicely complement a case study or could be used in lieu of a clinical learning situation.
Technical Requirements: The author has defined technical requirements as a computer with an Internet
connection, a browser, and Flash software. In addition, a soundcard and speakers
are strongly suggested. The activity can be accessed without the use of sound
but the attendant lectures provide useful information and direction.

Evaluation and Observation

Content Quality

Rating: 5 stars
Strengths: The content is solid, clearly presented, and highly significant for accurate evaluation of cardiac function. The participant can repeat the audio content and simulated electrode placement as often as needed for content mastery.
Concerns: No concerns.

Potential Effectiveness as a Teaching Tool

Rating: 5 stars
Strengths: The learning module depicts a core concept. It is well-organized, accurate and valid.
Concerns: There are no concerns.  The site could be enhanced
with links to other resources.

Ease of Use for Both Students and Faculty

Rating: 5 stars
Strengths: Very easy to use. Allows students to practice in a nonstressful situation. It is simple, colorful, and interactive. The user can complete the learning module in less than five minutes.
Concerns: No concerns.

Other Issues and Comments: No other issues
