用无创性程序胸壁刺激法和起搏器检测器,对51例起搏患者进行68次检测,发现强依赖型7例。起搏频率下降10％,起搏器不应期>500ms,急需更换起搏器者2例。检测结果表明:胸壁刺激法可估价起搏紧急故障下病人心脏的自律性,程序胸壁刺激法可估价起搏器电池耗竭后心脏的自律性,两者均可作为起搏器随访指标,后者较前者安全可靠。
Using noninvasive procedures chest wall stimulation and pacemaker detector, 51 cases of pacing patients were detected 68 times and found that 7 cases were strongly dependent. Pacemaker frequency decreased 10%, pacemaker refractory period> 500ms, urgent need to replace pacemaker in 2 cases. The test results show that chest wall stimulation can evaluate the self-discipline of the patient’s heart under the pacing emergency, and the chest wall stimulation can evaluate the self-discipline of the pacemaker battery after exhaustion, both of which can be used as the pacemaker follow-up index, More secure than the former.
