A 52-year-old woman who had acute heart failure with severe left ventricular systolic dysfunction and left bundle branch block was admitted to a university medical center. Contrast-enhanced magnetic resonance images of the heart did not show any evidence of myocardial infarction or myocarditis. Rate-related left bundle branch block and subsequent left ventricular dyssynchrony resulted in acute systolic dysfunction that resolved with beta-blockade therapy that allowed heart rate control and narrowing of the QRS complex. Of note, the use of inotropic agents would have dramatically worsened the cardiac condition.<\/jats:p>","DOI":"10.4037\/ajcc2010310","type":"journal-article","created":{"date-parts":[[2010,5,1]],"date-time":"2010-05-01T07:04:15Z","timestamp":1272697455000},"page":"e12-e14","source":"Crossref","is-referenced-by-count":2,"title":["Acute Heart Failure Due to Transient Left Ventricular Dyssynchrony: Case Study"],"prefix":"10.4037","volume":"19","author":[{"given":"Matthieu","family":"Jourdain","sequence":"first","affiliation":[{"name":"Matthieu Jourdain was a fellow in the intensive care unit, Jean Jacques Bauchart is a consultant in the intensive care unit and the cardiac catheterization laboratory, and Jean Luc Auffray, Philippe Asseman, and Pierre Vladimir Ennezat are consultants in the intensive care unit at the Cardiology Hospital of the Centre Hospitalier Re\u0301gional et Universitaire in Lille, France.
