Below we have listed our selection of the 8 highest quality blog posts related to 3 advanced level questions on cardiovascular topics posed, curated, and approved for residency training by the AIR-Pro Series Board. The blogs relate to the following questions:

  1. Advanced concepts about Sgarbossa’s Criteria
  2. Troubleshooting pacemaker’s and automated implantable cardioverter defibrillators (AICD’s)
  3. Troubleshooting left ventricular assist devices (LVAD’s)

In this module, we have 5 AIR-Pro’s and 3 Honorable Mentions. To strive for comprehensiveness, we selected from a broad spectrum of blogs identified through

AIR-Pro Stamp of Approval and Honorable Mentions

In an effort to truly emphasize the highest quality posts, we have two subsets of recommended resources. The AIR-Pro stamp of approval will only be given to posts scoring above a strict scoring cut-off of ≥28 points (out of 35 total), based on our AIR-Pro scoring instrument, which is slightly different from our original AIR Series scoring instrument. The other subset is for “Honorable Mention” posts. These posts have been flagged by and agreed upon by AIR-Pro Board members as worthwhile, accurate, unbiased, appropriately referenced, and have a score of 26-27. All posts will still be part of the quiz needed to obtain III credit. To decrease the repetitive nature of posts relating to these advanced concepts, we did not always include every post found that met the score of ≥28 points.
