Table 4 Predictors of echocardiographic response

From: Prediction of response to cardiac resynchronization therapy using left ventricular pacing lead position and cardiovascular magnetic resonance derived wall motion patterns: a prospective cohort study

  Univariate Multivariate
Variable Odds ratio 95 % confidence interval P value for logistic regression Odds ratio 95 % confidence interval P value for logistic regressiona

  1. aNo significant difference with 1000 sample bootstrapped multivariate logistic regression analysis
  2. (p = 0.012 for T2CL, p = non-significant for all others)
  3. bA favorable ECG pattern is indicated by the presence of a true left bundle branch block and a QRS duration > 150 ms
  4. ECG = Electrocardiogram; NICM = Non-Ischemic Cardiomyopathy; T2CL = Type II wall motion pattern and a concordant left ventricular lead
