Cardiac 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 کاملCardiac 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 کاملDifferential response to cardiac resynchronization therapy and clinical outcomes according to QRS morphology and QRS duration.
OBJECTIVES The goal of this study was to examine the relative impact of QRS morphology and duration in echocardiographic responses to cardiac resynchronization therapy (CRT) and clinical outcomes. BACKGROUND At least one-third of all patients treated with CRT fail to derive benefit. Patients without left bundle branch block (LBBB) or patients with smaller QRS duration (QRSd) respond less or n...
متن کاملOCUS ISSUE: CARDIAC RESYNCHRONIZATION THERAPY Normal QRS Duration and Resynchronization
Cardiac resynchronization therapy has been shown to be an effective treatment for patients with systolic ventricular dysfunction, prolonged ( 120 ms) QRS duration, and New York Heart Association (NYHA) functional class III or IV symptoms despite optimal medical therapy. However, studies show that a majority of heart failure patients have QRS duration 120 ms. We have been investigating the poten...
