Comparison of left ventricular-biventricular pacing on ventricular synchrony, mitral regurgitation, and global left ventricular function in patients with severe chronic heart failure

Am J Cardiol. 2004 Aug 15;94(4):519-21. doi: 10.1016/j.amjcard.2004.04.072.

Abstract

We compared the effects of left ventricular and biventricular pacing in 16 patients (15 men and 1 woman; aged 64 +/- 8 years) with severe heart failure by conventional and tissue Doppler echocardiography. Intraventricular synchrony, regional and global systolic function, diastolic function and filling time, and the severity of secondary mitral regurgitation were similar between left ventricular and biventricular pacing.
