Commotio Cordis

What this episode covers

<br /> Commotio cordis is caused by the blunt impact of a hard object directly over the heart occurring during a specific window of ventricular repolarization leading to immediate collapse, ventricular fibrillation, and cardiac arrest. This episode focuses on risk factors and management of this rare but catastrophic injury.<br /> <br /> <br /> <br /> <a rel="noreferrer noopener" href="http://www.pwmblog.com" target="_blank">PEMBlog</a><br /> <br /> <br /> <br /> <a href="http://twitter.com/PEMTweets">@PEMTweets on Twitter</a><br /> <br /> <br /> <br /> <a rel="noreferrer noopener" href="https://med-mastodon.com/@bradsobo" target="_blank">My Mastodon account @bradsobo</a><br /> <br /> <br /> <br /> <a href="https://cpr.heart.org/en/cpr-courses-and-kits/heartsaver/heartsaver-first-aid-cpr-aed-training" target="_blank" rel="noreferrer noopener">American Heart Association CPR and AED Training</a><br /> <br /> <br /> <br /> References<br /> <br /> <br /> <br /> Link MS.
