本文介绍经食管心房起搏治疗长 QT 间期综合征(LQTS)并发尖端扭转型室性心动过速(TSYT)引起阿斯综合征频繁发作2例,疗效满意,应用方便、快速.例1,女,60岁。患者近1年多来常因情绪激动而致反复昏厥,曾二次住本院,这次又因情绪激动后反复3次昏厥而于1983年9月21日第三次入院.体检:血压120/70.心率76,频发早搏.余无特殊发现。血钾4.4mmol/L.多次心电图示 U 波明显大于 T 波,T、U 融合,QT(U)c 0.61秒,阿斯综合征发作时可见 TSVT,记录到的最长一次 TSVT持续39秒.患者入院当日阿斯综合征反复发作,末次阿斯综合征发作时又心音消失,一边作心脏挤压,同时插入食管电极导管作心房起搏,导管插入33cm,输出脉冲电压35V、脉宽2ms,起搏频率94
This article describes transesophageal atrial pacing in patients with long QT syndrome (LQTS) complicated by torsades de pointes ventricular tachycardia (TSYT) caused by frequent attacks of Asper’s syndrome in 2 cases, the effect is satisfactory, the application is convenient and fast.Examples 1, Female, 60 years old. In the past year or so, patients often fainted repeatedly because of agitation. They had lived in our hospital twice, and were again admitted for the third time on September 21, 1983 after experiencing agitation for 3 times. Physical examination: blood pressure 120 / 70. Heart rate 76, frequent premature beats. I found no special. Potassium potassium 4.4mmol / L. Multiple ECG U wave was significantly greater than the T wave, T, U fusion, QT (U) c 0.61 seconds, visible as TSVT onset of Asperger syndrome, recorded the longest a TSVT lasted 39 seconds Asymptomatic patients recurrent on the day of admission, the last attack of Asyndrome disappeared again while the heart, while the heart squeeze, while inserting esophageal catheter for atrial pacing, catheter insertion 33cm, the output pulse voltage 35V, pulse width 2ms , Pacing frequency 94
