观察研究表明传统的右室心尖部起搏对左室功能可能有不利影响。
Observational studies suggest that conventional right ventricular apical pacing may have a deleterious effect on left ventricular function.
目的探讨左室显影(LVO)对前壁和侧壁心尖段的形态及运动的诊断意义。
Objective To discuss the significance of left ventricular opacification (LVO) for observing the shape and movement of apical anterior and lateral walls.
ICM左室大多数呈“圆拱门形”心尖圆钝变薄、收缩期运动明显低平，节段性室壁运动障碍及主动脉增宽为其特点。
The patients with ICM were characterized by thin spherical apex of left ventricle with hypokinesis, regional wall motion and dilated aorta.
