| 摘 要： | 目的：搪塞改变在体犬右心负荷对其电生理参数的影响。方法：改变右房、右室负荷，测定右房，右室舒张期阈值（ＡＤＰ、ＶＤＴ）；右房、右室相对流尖期（ＡＲＲＰ，ＶＲＲＰ）和右房，右室有效不庆期（ＡＥＲＰ，ＶＥＲＰ）。结果：分级（Ａ级和Ｂ级），机械性地部分阻断右房至右室的血流，右房峰值压力（ＰＲＡＰ）升高和有右室峰值压力（ＰＲＶＰ）降低使人ＡＥＲＰ和ＶＲＲＰ延长；但未发现ＡＤＴ，ＶＤＴ有明显变化。亦未出现

| Abstract: | AIM:To study the effects of changing right heart load on electrophysiologic parameters in anesthetized dogs. METHODS:Change of right atrial and ventricular load, right atrial and ventricular diastolic threshold (ADT, VDT), right atrial and ventricular relative refractory period (ARRP,VRRP) and right atrial and ventricular effective refractory period (AERP, VERP) were recorded. RESULTS: Increasing right heart load step by step(grade A and B) caused prolongation of ARRP, AERP, VRRP (grade B, P <0.01), but it was not in ADT and VDT, and atrial and ventricular arrhythmia was not induced. CONCLUSION: Mechanical and partial obstructing blood flow from right atria to right ventricle (changing right heart load)would prolong atrial and ventricular refractory period. |
