心房感知心房起搏(AAI)是一种既经济又简单实用的生理性起搏。广泛推广AAI起搏的关键在于:适应证的选择、心房电极的固定和电极导管及起搏参数的调试。我院安置AAI起搏器三例患者均为女性,年龄52～60岁,有持续性窦性心动过缓5～20年,伴头昏黑矇。食管调搏检查窦房结恢复时间1920～2040ms,房室结文氏阻滞点140～180次/分,例1有频发房性早搏、短阵房性心动过速。均诊断为病态窦房结综合征(SSS)。采用秦明公司Pinnacle 8619型起搏器及J型心房电极导管。经右侧锁骨下静脉穿刺,将直钢丝插入J形电极导管内,使电极J形头变直,送入锁骨下静脉。经上腔、右房至下腔静脉入口处。将X线球管调至右前斜位45°,后撤电极内钢丝约5厘米,电极即恢复J形。调整电板方向,使J形
Atrial Sense Atrial Pacing (AAI) is an economical, simple and practical physiological pacing. Extensive promotion of AAI pacing the key is: indications of choice, atrial electrode fixation and lead and pacing parameters debugging. Our hospital placement of AAI pacemaker in three patients were female, aged 52 to 60 years, with persistent sinus bradycardia 5 to 20 years, with dizzy. Esophageal pacing check sinus node recovery time 1920 ~ 2040ms, atrioventricular node resistance Wenshan 140 points to 180 beats / min, a case of frequent atrial premature beats, short atrial tachycardia. All diagnosed as sick sinus syndrome (SSS). Using Qin Pinnacle 8619 pacemaker and J-type atrial catheter. The right subclavian vein puncture, the straight wire inserted into the J-shaped electrode catheter, the electrode J-shaped head straight into the subclavian vein. The upper chamber, right atrium to the entrance of the inferior vena cava. X-ray tube will be transferred to the right front oblique 45 °, retracting the electrode wire about 5 cm, the electrode that is restored J-shaped. Adjust the board direction so that J-shaped
