我们对一例病态窦房结综合征伴眩晕患者安装了AAI起搏器,并进行了血流动力学观察。女性患者,47岁。以头晕、黑矇、胸闷反复发作,持续性心动过缓8年,出现眩晕而入院。查体:Bp12/9.3kPa(90/70mmHg),心界正常,心率42次/分,律不齐,各瓣膜区无病理性杂音,双肺(一)。ECG:窦性心动过缓,窦性停搏,P-R间期及QRS波群时限正常。DCG:24小时平均心率为49次/分,最快心率99次/分,最慢为30次/分,连续出现窦性停搏,P-P间期>3000ms共325次,最长为4600ms。心房调搏SNRT:3730ms,CSNRT:2382ms,文氏阻滞点150次/分,IHR75次/分。诊断为病态窦房结综合征,窦房结起搏功能障碍,房室传导功能正常。经右锁骨下静脉穿刺插入J形心房电极固定于右心耳内,测P波幅度4mV,起搏阈值电压1.0V。将起搏器(Pinnade
We installed an AAI pacemaker on a patient with sick sinus syndrome and vertigo and performed hemodynamic observations. Female patient, 47 years old. To dizziness, dark, chest tightness, recurrent, persistent bradycardia for 8 years, appeared dizzy and admitted to hospital. Examination: Bp12 / 9.3kPa (90 / 70mmHg), normal heart rate, heart rate 42 beats / min, irregular arrhythmia, the valve area without pathological murmurs, lungs (a). ECG: sinus bradycardia, sinus arrest, P-R interval and QRS wave group normal duration. DCG: 24 hours average heart rate 49 beats / min, the fastest heart rate 99 beats / min, the slowest 30 beats / min, continuous sinus arrest, P-P interval> 3000ms a total of 325 times, the longest 4600ms. Atrial pacing SNRT: 3730ms, CSNRT: 2382ms, Wen’s block point 150 beats / min, IHR75 beats / min. Diagnosis of sick sinus syndrome, sinus node pacing dysfunction, atrioventricular conduction function is normal. The right subclavian vein puncture inserted J-shaped atrial electrode fixed in the right atrial appendage, measured P wave amplitude 4mV, pacing threshold voltage 1.0V. Pacemaker (Pinnade
