Effects of left ventricular pacing on cardiac performance and on quality of life in patients with drug refractory heart failure.
We assessed the effects of left ventricular pacing on echocardiographic and clinical parameters in 13 consecutive patients with heart failure and bundle branch block by means of a controlled acute and medium-term evaluation. Left ventricular pacing induced a significant improvement in left ventricular ejection fraction, Minnesota Living with Heart Failure Questionnaire score, New York Heart Association class, and 6-minute walking test compared with sinus rhythm or right ventricular pacing.
