This booster provides practice of some of the most common cardiac dysrhythmias. What you will see in this booster is the rhythms produced by the electricity that is generated within the cardiac cells. A repetitive step by step approach can help you systematically analyze each heart rhythm for interpretation. These files are SCORM packages and can be easily uploaded to your Learning Management System (LMS), such as Blackboard or Desire2Learn. If you want to view or use the files without an LMS, download the files to your computer, extract (unzip) the file, open the extracted folder, and click to open the story.html file. The booster or test will open in your browser window. If used on your LMS, for the booster, the user will be given a score of complete or incomplete; for the pre and post-tests, the user will be given a numerical score. This scoring functionality and completion data is only available if used on an LMS. The SCORM packages are complete and not available for editing. If you would like to include additional information, consider adding the content before or after the booster on your LMS.
