This patient has a biventricular pacemaker with one lead in the RV (also his ICD lead), and a second wire into the coronary sinus (thinner lead extending further to the left heart wall). This pacer produces simultaneous biventricular activation and is often used now in patients with significant heart failure.<\/p>\n<p><a href=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2016\/05\/293.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-547\" src=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2016\/05\/293.png\" alt=\"293\" width=\"261\" height=\"249\" \/><\/a> <a href=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2016\/05\/294.png\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-548\" src=\"http:\/\/torreyekg.com\/wp-content\/uploads\/2016\/05\/294.png\" alt=\"294\" width=\"196\" height=\"249\" \/><\/a><\/p>\n<p><\/p><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Does this ventricular paced complex look different from usual?<\/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-544","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\/544","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=544"}],"version-history":[{"count":2,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/544\/revisions"}],"predecessor-version":[{"id":550,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/posts\/544\/revisions\/550"}],"wp:attachment":[{"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/media?parent=544"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/categories?post=544"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/torreyekg.com\/index.php\/wp-json\/wp\/v2\/tags?post=544"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
