Further evaluation of the wide QRS complex also reveals a short PR interval \u2013 this is Wolff-Parkinson-White syndrome with a bypass tract that conducts intermittently.   Thus it is a great comparison of a normal AV node conducted complex with the altered complex of Wolff-Parkinson-White (a \u201cfusion\u201d of AV node-His-Purkinje conduction with abnormal ventricular depolarization via a bypass tract).\n<p>The trick to this EKG is to recognize WPW as the cause for the wide complex beats \u2013 it might be tempting to diagnose bigeminy, or even, intermittent LBBB.<br \/>\n<\/p><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>40-year-old woman with palpitations earlier this day.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3],"tags":[],"class_list":["post-707","post","type-post","status-publish","format-standard","hentry","category-ekg-of-the-week"],"_links":{"self":[{"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/707","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/comments?post=707"}],"version-history":[{"count":3,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/707\/revisions"}],"predecessor-version":[{"id":722,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/707\/revisions\/722"}],"wp:attachment":[{"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/media?parent=707"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/categories?post=707"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/tags?post=707"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
