Exercise, a physiologic stress, has been used in adults to unmask abnormalities of left ventricular hemodynamics not detectable at rest. Similar data in children are not available. An evaluation was made of the feasibility, safety and value of a graded upright and supine ergometer stress test to assess exercise hemodynamics during cardiac catheterization in 21 children with left-sided cardiac disease. The catheterization technique involved the simultaneous recording of intracardiac and great vessel pressures, thermodilution cardiac index and M mode echocardiograms of the left ventricular cavity. The method appears practical and safe. Although hemodynamic responses varied among clinical groups, the lack of control data currently prevents assessment of the value of this technique for long-term management.
运动作为一种生理应激，已被应用于成人以揭示静息时无法检测到的左心室血流动力学异常。儿童方面的类似数据尚不明确。本研究对21例患有左侧心脏病的儿童在心脏导管插入术期间进行分级直立和仰卧测力计应激试验以评估运动血流动力学的可行性、安全性及价值进行了评估。导管插入术技术包括同时记录心内和大血管压力、热稀释心排血量及左心室腔的M型超声心动图。该方法似乎切实可行且安全。尽管不同临床组的血流动力学反应有所不同，但目前缺乏对照数据，妨碍了对该技术在长期管理中的价值进行评估。
