Abstract : it is necessary to control the mechanical stimuli precisely in the studies of cardiac mechano - electrical feedback ( mef ) . in the present study a ventricular pressure - clamping system has been developed , which can be applied to isolated - perfused rabbit hearts . controlled by a computer , this system not only can make the left ventricle follow a command defining the same pressure wave as that during a beating cycle under physiological condition , but also deliver mechanical stimuli with a proper waveform to the ventricle at a particular time phase . this system integrates multiple functions , including perfusing , pacing , recording of electrocardiogram and monophasic action potentials , and clamping and measuring of ventricular pressures in isolated - perfused hearts . thus , it is a distinct system for investigating the phenomena and mechanisms of cardiac mef at organ level 文摘:在心臟機械電反饋的研究中準確控制機械刺激是非常重要的.本研究室構建了一套適用于離體家兔心臟的心室壓力鉗系統.該系統通過計算機控制壓力鉗,不僅能模擬正常生理條件下左心室的壓力波形,還能在心室活動周期的特定時相、以適當波形對心室施加機械刺激.該系統集心臟灌流與起搏、表面心電圖記錄、單相動作電位記錄、心室壓力鉗制與測定等多種功能于一體,特別適用于器官水平上觀察機械電反饋現象并探討其機制
