由于 T 波电压交替致起搏器超感知现象(Oversensing)临床上很少见到,笔音近日发现一例现报告如下.病例简介患者男性,73岁.1987年6月19日因全身浮肿、伴呼吸困难半年余,加重月余,诊断冠心病、Ⅲ度房室传导阻滞、心衰Ⅲ度,合并心包、胸腔积液入院。经吸氧、休息、利尿剂、血管扩张剂治疗病情无明显改善。于1987年6月23日置入 YCP—Ⅱ型起搏器(重庆华伟产、编号84470).术中经过顺利.腔内心电图 R 波振幅为11.1mV,ST 上抬3.5mV,起搏阈值0.9V.术后24小时测定 Due to the T wave alternating voltage induced pacemaker over-awareness of the phenomenon (Oversensing) clinically rare, a recent case of stroke was reported as follows.Patients profile Male patients, aged 73. June 19, 1987 due to systemic edema, with More than six months of breathing difficulties, increased more than a month, the diagnosis of coronary heart disease, Ⅲ degree atrioventricular block, heart failure Ⅲ degree, combined pericardial, pleural effusion admission. The oxygen, rest, diuretics, vasodilators no significant improvement in condition. On June 23, 1987, the YCP-Ⅱ pacemaker (Hua Wei, Chongqing No. 84470) was placed in operation.The intracranial ECG R wave amplitude was 11.1 mV, the ST elevation was 3.5 mV, and the pacing threshold 0.9V. Determination of 24 hours after surgery
