作者报告一组急性特发性渗出性心包炎病例,于渗出期末出现一过性心脏缩窄而以后自行恢复正常。177例急性特发性渗出性心包炎中发现16例有一过性心脏缩窄(男10例,女6例),年龄8～59(年龄38)岁。全部病例均行 M 型超声心动图检查,以检出心包积液和室间隔舒张早期切迹,并行颈静脉脉搏检查。以左、右心导管行血液动力学检查,并以1000ml 生理盐水于8min 内静脉输注后重测压力和心排出量。结果全部病例均有下列各期。Ⅰ期(心包积液):全部病例超声心动图证实有中至大量心包积液,其中9例并发胸积液。3例有心脏填塞。6例曾 The authors report a group of patients with acute idiopathic exudative pericarditis that had a transient cardiac constriction at the end of exudation and returned to normal afterwards. A total of 177 cases of acute idiopathic exudative pericarditis were found in 16 cases of transient cardiac constriction (10 males and 6 females), aged 8 to 59 (38 years of age). All cases underwent M-mode echocardiography to detect pericardial effusion and ventricular diastolic early notch, parallel to the jugular vein pulse examination. Hemodynamic examination was performed with left and right cardiac catheters, and the pressure and cardiac output were measured again with intravenous infusion of 1000ml normal saline within 8 minutes. Results All cases had the following periods. Stage I (pericardial effusion): Echocardiography was confirmed in all cases with moderate to large pericardial effusion, of which 9 cases had concurrent pleural effusion. 3 cases of heart packing. 6 cases ever
