EF improvement by 7.5% (n=30)
VariablesOR (95% CI)P value
R-R dispersion (per 100 unit increase)1.59 (1.00 to 2.55)0.03
LVIDd, mm (per 10 unit increase)0.57 (0.10 to 3.17)0.51

  • *Restricted to echocardiographic and ECG variables only due to limited sample size, keeping all variables from table 1 with univariable p value <0.10.

  • EF, ejection fraction;LVIDd, left ventricular internal diameter during end-diastole;LVIDs, left ventricular internal diameter during end-systole.
