Cardiac resynchronization therapy
Current Cardiology Reports, 2005Cardiac resynchronization therapy (CRT) addresses abnormal left ventricular (LV) activation that produces detrimental effects on cardiac systolic and diastolic function. CRT improves symptoms and ventricular performance, promotes reverse remodeling, and decreases mortality and hospitalization in patients with congestive heart failure (CHF).

Spontaneous cardiac resynchronization
Journal of Electrocardiology, 2004A 73-year-old woman with dilated cardiomyopathy presented with heart failure. The ECG showed sinus rhythm with left bundle branch block, left-axis deviation and prolonged QRS duration and frequent ventricular premature complexes from the left ventricular septal wall were present.

Physiology of cardiac resynchronization
Current Cardiology Reports, 2004Dyssynchronous ventricular contraction, often associated with delayed electrical activation, contributes to worsened clinical status in patients with chronic dilated heart failure. There are three levels of impaired electromechanical synchrony that can be recognized and potentially improved with pacing methods. Prolonged atrioventricular (AV) delay can

Cardiac resynchronization therapy
Current Treatment Options in Cardiovascular Medicine, 2008It is now well established that electrical and mechanical dyssynchrony are not clinically synonymous; however, at present no individual noninvasive method can reliably and consistently identify the criteria for mechanical dysfunction correctable through device therapy. The results of the PROSPECT (Predictors of Response to CRT) trial not only highlight

Myocardial Dyssynchrony and Resynchronization
Heart Failure Clinics, 2006Heart failure is a common cardiovascular condition with more than 500,000 new cases each year and requiring close to 1 billion dollars in health care expenses [1]. During the last decade or so, several publications have noted the prevalence and unfavorable effects of conduction abnormalities in heart failure [2–5].

Cardiac resynchronization therapy
British Journal of Hospital Medicine, 2013This article provides an overview of cardiac resynchronization therapy. At the end of the article, the reader should be familiar with the indications, risks and complications of cardiac resynchronization therapy and important areas of debate.

Cardiac Resynchronization Therapy
Critical Care Nursing Quarterly, 2007About 30% of patients with left ventricular systolic dysfunction also have ventricular conduction delays (prolonged QRS duration greater than 0.12 second) most frequently seen as left bundle branch block. This intraventricular conduction delay causes nonsynchronous ventricular activation between the right ventricle and the left ventricle (or ...

Cardiac resynchronization therapy
Current Cardiology Reports, 2002Despite advances in medical therapy for patients with congestive heart failure, morbidity and mortality remain high. Conventional atrioventricular pacing with a short atrioventricular delay was first introduced as a nonpharmacologic treatment for patients with severe heart failure.

Heart Failure Reviews, 2011
Although there is little debate over the fact that cardiac resynchronization therapy (CRT) can benefit the majority of patients selected with routine indications, the precise mechanism for improvement may be considered controversial. Among patients selected with New York Heart Association functional class III or IV symptoms, left ventricular ejection ...
