目的探讨经食管临时心脏起搏技术在手术患者中的应用的可行性。方法在21例有缓慢性心律失常的非食管手术患者中应用经食管临时心脏起搏技术。结果所有患者都顺利完成手术治疗,电极到位率100%,左房起搏有效率100%,临时心脏起搏持续时间平均(2.5±0.6)h。起搏参数:起搏频率60次/min;脉宽1.5~5.5(3.2±1.4)ms;起搏电压15~40(30±8)V。结论我们认为临床上对有缓慢性心律失常需要处理的非食管手术患者值得推广应用经食管临时心脏起搏技术。
Objective To investigate the feasibility of transesophageal elective cardiac pacing in surgical patients. Methods Transient esophagectomy was used in 21 patients with non-esophageal surgery with arrhythmia. Results All patients underwent surgical treatment successfully. The rate of electrode placement was 100%, the efficiency of left atrial pacing was 100%, and the duration of temporary cardiac pacing was 2.5 ± 0.6 h. Pacemaker parameters: pacing rate 60 beats / min; pulse width 1.5 to 5.5 (3.2 ± 1.4) ms; pacing voltage 15 to 40 (30 ± 8) V. Conclusions We believe that clinical non-esophageal surgery for patients with chronic arrhythmia should be promoted using transesophageal temporary pacing.
