Table 5. Changes in the left and right ventricular and atrial dimensions in systole and diastole in normal pregnancy among the study participants.

*Statistically significant

LVPWd (cm): left ventricular posterior wall in diastole, LAD (cm): left atrial diameter, LVPWs: left ventricular posterior wall in systole, LVIDs: left ventricular internal diameter in systole, LVIDd: left ventricular internal diameter in diastole, LAVs: left atrial volume in systole, LAVI: left atrial volume index, RVD1 (cm): right ventricular basal diameter (basal diameter), RAD (cm): right atrial diameter, RAV (cm): right atrial volume, CI: confidence interval
