目的 :观察双腔起搏器自动模式转换功能在房性心律失常治疗中的应用效果。方法 :2 1例患者分别植入MedtronicInc .KappaKDR73 1或 73 3型双腔起搏器 ,分别于术后第 4d、1个月及每隔 3个月一次跟踪随访 ,观察房性心律失常的发生情况和起搏器自动模式转换情况及临床症状。结果 :全部病例随访 1～ 18个月 ,共出现阵发性房颤、房扑及房性心动过速 62阵次 ,起搏后由DDD(R)自动转换成DDI(R)模式 5 8阵次 ,患者自觉心悸 9阵次。结论 :①MedtronicInc .Kap paKDR70 0系列具有良好的房性心动过速诊断和自动模式转换功能。②自动模式转换功能可使起搏器在患者发作房性心动过速时发挥对心室的保护作用 ,有效避免由于起搏器跟踪快速心房率而造成心室率过快 ,引起的血流动力学改变 ,并能明显减轻心悸等临床症状 ,提高病人的舒适性和安全性
Objective: To observe the effect of automatic mode switching of dual chamber pacemaker in the treatment of atrial arrhythmia. Methods: Twenty-one patients were implanted MedtronicInc. KappaKDR73 1 or 73 3 double-chamber pacemaker, followed by a follow-up at 4 days, 1 month and 3 months after operation to observe the occurrence of atrial arrhythmia Situation and pacemaker automatic mode conversion and clinical symptoms. Results: All cases were followed up for 1 ~ 18 months. A total of 62 paroxysmal atrial fibrillation, atrial flutter and atrial tachycardia were seen. DDD (R) was automatically converted to DDI (R) mode after pacing Times, patients consciously palpitations 9 array. Conclusion: ①MedtronicInc. Kap paKDR70 0 series has a good diagnosis of atrial tachycardia and automatic mode conversion. ② automatic mode conversion function allows the pacemaker in patients with atrial tachycardia play a protective role in the ventricle, effectively avoid the pacemaker tracking rapid atrial rate caused by excessive ventricular rate, resulting in hemodynamic changes , And can significantly reduce clinical symptoms such as palpitations, improve patient comfort and safety
