Cardiac index, left ventricular index, left ventricle wall thickness and diameter of myocardial cell were recorded.
计算心脏指数、左心室指数、左心室的厚度、心肌细胞直径。

The results showed that transverse diameter. longitudinal diameter of the heart. cardiac area and cardio- thoracic ratio decreased markedly after labor(P<0.01 ).
结果：心脏横径、心脏长径、心脏面积、心胸比率较初入高原时显著缩小（P＜0．01）；

Select the left and right atria, ventricular end systolic and end diastolic diameter, diameter, diameter change as indicators to determine changes in cardiac shape.
