Beyond three or five consecutive premature ventricular complexes (depending on definition), it is common to use the term nonsustained ventricular tachycardia (if lasting less than 30 seconds).\r\n\r\nPremature ventricular complexes in the setting of arrhythmogenic right ventricular dysplasia usually originate from the right ventricle (left delay) and are related to the location of the fibro-adipose infiltrates. They are shorter, wider, and often polymorphic and notched (different pathological foci, along with slowed and disorganized propagation within the ventricular myocardium), allowing to differentiate these asystoles from benign infundibular premature ventricular complexes. The response to catecholaminergic stimulation (exercise test, isoproterenol test) also differs with a significant increase in exercise irritability. Premature complexes are sometimes the first sign of the onset of this cardiomyopathy.","ecg_info_post_answer":"<img class=\"alignnone wp-image-10866 size-large\" src=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/06\/trace-5-10-ecg-en-1024x576.jpg\" alt=\"\" width=\"800\" height=\"450\" \/>"},"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.0 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Trace 5.10: Ventricular doublets and ventriculaires et arrhythmogenic right ventricular cardiomyopathy - Cardiocases<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/cardiocases.com\/fr\/ecg_case\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\/\" \/>\n<meta property=\"og:locale\" content=\"fr_FR\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Trace 5.10: Ventricular doublets and ventriculaires et arrhythmogenic right ventricular cardiomyopathy - Cardiocases\" \/>\n<meta property=\"og:url\" content=\"https:\/\/cardiocases.com\/fr\/ecg_case\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\/\" \/>\n<meta property=\"og:site_name\" content=\"Cardiocases\" \/>\n<meta property=\"article:modified_time\" content=\"2026-06-29T10:29:40+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/cardiocases.com\/wp-content\/uploads\/2026\/03\/trace-5-10-ecg-2-scaled.jpeg\" \/>\n\t<meta property=\"og:image:width\" content=\"2560\" \/>\n\t<meta property=\"og:image:height\" content=\"1263\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<meta name=\"twitter:label1\" content=\"Dur\u00e9e de lecture estim\u00e9e\" \/>\n\t<meta name=\"twitter:data1\" content=\"1 minute\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\\\/\\\/schema.org\",\"@graph\":[{\"@type\":\"WebPage\",\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/\",\"url\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/\",\"name\":\"Trace 5.10: Ventricular doublets and ventriculaires et arrhythmogenic right ventricular cardiomyopathy - Cardiocases\",\"isPartOf\":{\"@id\":\"https:\\\/\\\/cardiocases.com\\\/#website\"},\"primaryImageOfPage\":{\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/#primaryimage\"},\"image\":{\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/#primaryimage\"},\"thumbnailUrl\":\"https:\\\/\\\/cardiocases.com\\\/wp-content\\\/uploads\\\/2026\\\/03\\\/trace-5-10-ecg-scaled.jpeg\",\"datePublished\":\"2026-06-29T10:29:38+00:00\",\"dateModified\":\"2026-06-29T10:29:40+00:00\",\"breadcrumb\":{\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/#breadcrumb\"},\"inLanguage\":\"fr-FR\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/\"]}]},{\"@type\":\"ImageObject\",\"inLanguage\":\"fr-FR\",\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/#primaryimage\",\"url\":\"https:\\\/\\\/cardiocases.com\\\/wp-content\\\/uploads\\\/2026\\\/03\\\/trace-5-10-ecg-scaled.jpeg\",\"contentUrl\":\"https:\\\/\\\/cardiocases.com\\\/wp-content\\\/uploads\\\/2026\\\/03\\\/trace-5-10-ecg-scaled.jpeg\",\"width\":2560,\"height\":1263},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\\\/\\\/cardiocases.com\\\/ecg_case\\\/trace-5-10-ventricular-doublets-and-ventriculaires-et-arrhythmogenic-right-ventricular-cardiomyopathy\\\/#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"name\":\"Home\",\"item\":\"https:\\\/\\\/cardiocases.com\\\/\"},{\"@type\":\"ListItem\",\"position\":2,\"name\":\"Trace 5.10: Ventricular doublets and ventriculaires et arrhythmogenic right ventricular cardiomyopathy\"}]},{\"@type\":\"WebSite\",\"@id\":\"https:\\\/\\\/cardiocases.com\\\/#website\",\"url\":\"https:\\\/\\\/cardiocases.com\\\/\",\"name\":\"Cardiocases\",\"description\":\"Real cardiac device traces, pacemaker &amp;
