患者女性,35岁,工人,反复胸闷、心悸、头晕伴阵发性晕厥十五年。临床诊断:慢-快综合征,尖端扭转型室性心动过速伴阿-斯综合征发作。因药物控制不满意,于1988年5月安装秦明公司Pinnacle101型心脏起搏器,术后间断服用异搏定或小剂量心得安控制过速型心律失常。门诊随访,病情一直稳定,起搏功能良好。1991年7月中旬,患者在做上肢活动时突感心前区疼痛伴心悸、头晕及右胸壁安装起搏器部位皮肤、肌肉搏动。急查心电图提示:窦性心动过缓,频发房性早搏,起搏脉冲幅度较前明显减小,电信号仅有部分起搏心室,起搏器磁铁频率仍为72次/分,初步考虑起搏器不全移位收住院。
Female patient, 35 years old, worker, repeated chest tightness, palpitations, dizziness with paroxysmal syncope for fifteen years. Clinical diagnosis: slow - fast syndrome, torsades de pointes torsades de pointes ventricular tachycardia with Asperis syndrome onset. Due to drug control is not satisfied, in May 1988 to install Qin Pinnacle101 pacemaker, intermittent withdrawal of verapamil or low dose of propranolol after the control of tachyarrhythmias. Outpatient follow-up, the condition has been stable, pacing function is good. In mid-July 1991, the patient felt sudden pain in the anterior heart area with palpitations, dizziness, and wearing the pacemaker on the chest wall of his right chest. Urgent ECG check tips: sinus bradycardia, frequent atrial premature beats, pacemaker pulse amplitude was significantly reduced compared with the previous, the signal only part of the pacing ventricular pacemaker magnet frequency is still 72 beats / min, initially considered Pacemaker incomplete shift hospital.
