Correlation Coefficients of Systolic Time Intervals and Left Ventricular Ejection Fraction and Left Ventricular End‐Diastolic Pressure
| Systolic Time Intervals | LVEF | P‐Value | LVEDP | P‐Value | BNP | P‐Value |
|---|---|---|---|---|---|---|
| EMAT | −0.51 | <0.0001 | 0.16 | 0.14 | 0.16 | 0.14 |
| Q‐S2 | −0.39 | 0.0003 | 0.05 | 0.64 | 0.08 | 0.44 |
| LVST | −0.20 | 0.069 | −0.04 | 0.73 | 0.006 | 0.96 |
| EMAT/LVST | −0.41 | 0.0001 | 0.20 | 0.055 | 0.20 | 0.055 |
LVEF = left ventricular ejection fraction; LVEDP = left ventricular end‐diastolic pressure; BNP = B‐type natriuretic peptide; EMAT = electromechanical activation time; LVST = left ventricular ejection time.
