摘　　要：目的探讨生理性心脏起搏的临床应用。方法 2 1例患者 ,男性 14例 ,女性 7例 ,年龄42～ 81岁。病态窦房结综合征 10例 ,高度房室传导阻滞 9例 ,三束支传导阻滞 2例。植入DDDR 8例 ,DDD 10例 ,AAI 1例 ,VVIR 2例。结果植入各种类型生理性起搏器占同期植入起搏器总数的5 0 % ,其中双腔起搏器占 42 9% ,频率适应性起搏器占 2 3 8% ,均经穿刺锁骨下静脉送入心房和 /或心室电极 ,分别成功固定于右心耳或右室心尖部 ,测试起搏阈值、电极阻抗及P波或R波振幅均较满意。结论生理性心脏起搏符合生理需要 ,是较理想的起搏方式。Objective To investigate the practical valuation of three-dimensional (3D) sonagraphic imaging in diagnosis of gallstone. Methods To observe the feature of gallstone on 3D sonagraphic imaging, the gall bladders of 86 patients with cholelithiasis were examined by Kretz C-530 3D imaging system (volume 3.5 MHz transducer ) with the modes of 2D and/or 3D. 3D ultrasound restructions of gallstones in 65 cases of these patients were demonstrated with surface imaging mode. Results The structure of whole gall bladder, the size, number and form of stone and the relation between stone and gall bladder were clearly displayed by 3D sonographic imaging. Conclusion 3D ultrasound can provide more information than 2D.
