It has been associated with ventricular dysfunction in the setting of incessant tachycardia. We present the case of an otherwise healthy adolescent who had frequent DVR without tachycardia leading to left ventricular dysfunction. Slow pathway modification led to a significant reduction in ectopy and normalization of ventricular function. This highlights that DVR without tachycardia might lead to ventricular dysfunction in pediatric patients. Slow pathway modification with reduction of ectopy may be sufficient to restore ventricular function.<\/jats:p>","DOI":"10.1007\/s00246-024-03506-9","type":"journal-article","created":{"date-parts":[[2024,5,6]],"date-time":"2024-05-06T05:01:27Z","timestamp":1714971687000},"page":"499-503","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Double Ventricular Response with Aberrant Conduction Leading to Ventricular Dysfunction"],"prefix":"10.1007","volume":"46","author":[{"given":"Paul W.","family":"Warren","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adam W.","family":"Powell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy","family":"Knilans","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chad","family":"Connor","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shankar","family":"Baskar","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2024,5,6]]},"reference":[{"key":"3506_CR1","doi-asserted-by":"publisher","first-page":"85","DOI":"10.1016\/j.pcl.2005.10.004","volume":"53","author":"SJ Doniger","year":"2006","unstructured":"Doniger SJ, Sharieff GQ (2006) Pediatric dysrhythmias.
