What follows is a regular narrow-complex tachycardia at 150\/minute with an inverted P-wave preceding each QRS complex. The rate of 150\/minute raises the consideration of atrial flutter with 2:1 conduction, but in the lead II rhythm strip there is no indication of flutter waves at a rate of 300\/minute.  The regular, deeply-inverted P waves in lead II suggest an ectopic rhythm, and thus this short run of tachycardia is an ectopic tachycardia.<br \/>\n<\/p><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>50-year-old man complains of palpitations.<\/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-741","post","type-post","status-publish","format-standard","hentry","category-ekg-of-the-week"],"_links":{"self":[{"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/741","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/comments?post=741"}],"version-history":[{"count":1,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/741\/revisions"}],"predecessor-version":[{"id":744,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/741\/revisions\/744"}],"wp:attachment":[{"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/media?parent=741"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/categories?post=741"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/tags?post=741"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
