T-wave area predicts response to cardiac resynchronization therapy in patients with left bundle branch block.

Greater response to cardiac resynchronization therapy in patients with true complete left bundle branch block: a PREDICT substudy.

CONCLUSION: In patients with conventional wider LBBB morphology, the presence of mid-QRS notching or slurring is a strong predictor of better response to CRT. Multivariate analysis showed that t-LBBB (odds ratio, OR, 11.680 95% confidence interval, CI, 1.966-69.390 P = 0.007) and left ventricular end-diastolic dimension (OR, 0.891 95% CI, 0.797-0.996 P = 0.043) are independent predictors of super-response to CRT. All patients with t-LBBB were responders, some were super-responders. IVCD) and changes in mean New York Heart Association class were -1.2 ± 0.6 in t-LBBB, -0.8 ± 0.6 in nt-LBBB (P = 0.071), and -0.5 ± 0.6 in IVCD (P = 0.01, t-LBBB vs. At 6 month follow-up, mean absolute increases in left ventricular ejection fraction were 16.0% ± 11.6% in t-LBBB, 8.1% ± 11.2% in nt-LBBB (P = 0.02), and 3.3% ± 7.8% in IVCD (P < 0.001, t-LBBB vs. We prospectively enrolled 58 patients with heart failure and allocated them to three groups: true LBBB (t-LBBB, n = 22) non-true LBBB (nt-LBBB, LBBB with no notch or notches in fewer than two of the leads, n = 17) and non-specific intraventricular conduction delay (IVCD, n = 19).

METHODS AND RESULTS: We defined true LBBB as conventional LBBB plus QRS duration ≥ 130 ms and mid-QRS notching/slurring in at least two of the leads I, aVL, V1, V2, V5, or V6. N2 - AIMS: To determine whether patients with congestive heart failure and true left bundle branch block (LBBB) morphology have better response to cardiac resynchronization therapy (CRT) than do patients without true LBBB. JF - Europace : European pacing, arrhythmias, and cardiac electrophysiology : journal of the working groups on cardiac pacing, arrhythmias, and cardiac cellular electrophysiology of the European Society of Cardiology T1 - True complete left bundle branch block morphology strongly predicts good response to cardiac resynchronization therapy. We defined true LBBB as conventional LBBB plus QRS duration ≥ 130 ms and mid-QRS notching/slurring in at least two of the leads I, aVL, V1, V2, V5, or V6.
