The evaluation of the artificial pacemakers from hemodynamics and cardio-electrophysiology is relatively mature, while that from myocardial mechanics is needed.

从血流动力学和心电生理学方面对心脏人工起搏效果的评价相对成熟，而从心肌的机械活动方面的评价较少。

Assessment of the severity of PH is based on clinical parameters, functional tests (six-minute walk test), echocardiography and hemodynamics.

评价PH的严重程度是根据临床参数、功能试验（6分钟步行距离）、超声心动图和血流动力学参数。

Using an epidural catheter placed at the level of T1-2 or T2-3, seven patients scheduled for awake CABG received TEA for total arterial myocardial revascularization after partial lower sternotomy.Six patients remained awake and spontaneously breathing during the entire procedure, but one required intraoperative intubation for respiratory distress caused by phrenic nerve palsy. Hemodynamics were stable throughout surgery without significant arterial hypercarbia. All patients rated TEA as "good" or "excellent."

七个患者被安排在清醒的CABG接受TEA，在部分下肢手术后，使用安置於 T1-2 或 T2-3 的硬膜外导管，以进行总动脉的心肌血管更换术，其中六名患者保持清醒，并且在手术过程中自然地呼吸，但是一位患者因为隔膜神经瘫痪导致呼吸困难，而需要进行手术中的插管，血液动力学在手术过程中是稳定的，并未发生动脉的血中二氧化碳含量过高，所有患者认为TEA是&良好或极佳的&。

No thrombosis was found as well by means of examining kidney, membrane-pump and catheter. Conclusions PUCA pump can successfully maintain the hemodynamics in a sheep acute heart failure model associated with few blood destruction and thrombosis.

结论PUCA泵的短期辅助能稳定急性心力衰竭动物的血流动力学，并且无明显的血小板和红细胞破坏及血栓形成等并发症。

Methods After heart failure model was induced successfully in 10 sheep, PUCA pump was inserted through aorta and the aortic valve orifice with its tip located in the left ventricle. It was then activated to support the hemodynamics for 3 hours. Hemodynamic parameters were monitored and recorded before thoracotomy, heart failure, and every 60 min after the support. Platelet and plasma free hemoglobin were tested during the experiment.

方法对10只绵羊诱导左心衰竭模型建立成功后行PUCA泵辅助3h，监测并记录血流动力学参数，采动脉血人工计数血小板并测定血浆游离血红蛋白；经辅助3h后检查肾、隔膜泵及导管血栓形成的情况。
