Cardiac resynchronization therapy in patients with a narrow QRS complex.
OBJECTIVES The purpose of this study was to evaluate the effects of cardiac resynchronization therapy (CRT) in heart failure patients with narrow QRS complex (<120 ms) and evidence of left ventricular (LV) dyssynchrony on tissue Doppler imaging (TDI). BACKGROUND Cardiac resynchronization therapy is beneficial in selected heart failure patients with wide QRS complex (> or =120 ms). Patients wi...
متن کاملCardiac resynchronization therapy in patients with a narrow QRS.
Although cardiac resynchronization therapy (CRT) is indicated in patients with moderate to severe heart failure with a wide QRS complex (> 120 ms), current guidelines exclude many heart failure patients with a narrow QRS. Detecting mechanical dyssynchrony on echocardiography has become a promising tool in selecting patients with a narrow QRS who may respond to CRT. Several small single-center s...
متن کاملEffect of Gender on Outcomes After Cardiac Resynchronization Therapy in Patients With a Narrow QRS Complex
Cardiac resynchronization therapy (CRT) has been demonstrated to reduce morbidity and mortality in numerous large clinical trials, and it has become an integral part of contemporary heart failure therapy. The inclusion criteria of these trials form the basis of current guidelines, recommending CRT for patients with a severely reduced left ventricular ejection fraction of ≤35%, symptomatic chron...
متن کاملMetaanalysis on effects of cardiac resynchronization therapy in heart failure patients with narrow QRS complex.
BACKGROUND To systematically review the benefits of cardiac resynchronization therapy (CRT) in heart failure patients with narrow QRS (< 120 ms) who have baseline mechanical asynchrony. METHODS We searched the MEDLINE, Cochrane Central Register of Controlled Trials, and reference lists of retrieved articles for relevant trials through October 2007. Studies were included if they were clinical ...
متن کاملCardiac-resynchronization therapy in heart failure with a narrow QRS complex.
BACKGROUND Indications for cardiac-resynchronization therapy (CRT) in patients with heart failure include a prolonged QRS interval (> or =120 msec), in addition to other functional criteria. Some patients with narrow QRS complexes have echocardiographic evidence of left ventricular mechanical dyssynchrony and may also benefit from CRT. METHODS We enrolled 172 patients who had a standard indic...
