Table 3. Correlation between electrocardiographic PR and QRS width and end-systolic volumes of RV and LV.
correlationcoefficient, R | P value* | |
PR vs. RVESV | 0.21 | 0.014 |
QRS vs. RVESV | 0.24 | 0.006 |
PR vs. LVESV | 0.25 | 0.005 |
QRS vs. LVESV | 0.26 | 0.003 |
LVESV, left ventricular end-systolic volume; RVESV, right ventricular end-systolic volume.
P value calculated with linear regression analysis.
