例1 男68岁,因头晕、黑矇晕厥反复发作2个月,临床诊断冠心病,心律失常Ⅱ度Ⅱ型及高度房室传导阻滞伴阿-斯综合征,植入西航QB-1 VVI起搏器。起搏频率69次。阈值0.9V,脉宽0.53ms,阻抗508Ω。一周后起搏器失灵,脉冲信号72次/分、规则,不能夺获病人自身心搏,且呈Ⅲ度房室传导阻滞,室率30次/分,X线胸部平片未发现电极导管脱位及断裂。半小时后阿-斯综合征发作,再行临时心脏起搏。取出埋植的起搏器,发现电极插头与插孔插接不严,经重新插紧固定后,起搏功能恢复正常。插接松脱在临床上需与不全断裂和起搏阈值升高鉴别。这种现象的发生,主要是技术不熟练,经验不足所致。
Example 1 Male 68 years old, due to dizziness, hemophthalmia recurrent seizures for 2 months, clinical diagnosis of coronary heart disease, arrhythmia Ⅱ degree Ⅱ type and atrioventricular block with A - Syndrome, implanted XB-1 VVI pacemaker. Pacing frequency 69 times. Threshold 0.9V, pulse width 0.53ms, impedance 508Ω. A week after the failure of pacemaker, pulse signal 72 beats / min, the rules can not seize the patient’s own heart rate, and was Ⅲ degree atrioventricular block, room rate 30 beats / min, X-ray chest film was not found in the lead Dislocation and fracture. Half an hour after the onset of Alzheimer’s syndrome, and then temporary cardiac pacing. Remove the implantable pacemaker and found that the electrode plug and socket plug lax, after re-tightening fixed, pacing function returned to normal. Pin loose in clinical need to be broken and pacing threshold increased identification. The occurrence of this phenomenon is mainly due to inexperienced technology and inexperience.
