食道心房调搏具有操作简便、安全等特点,在临床心脏电生理检查及治疗中有着重要作用。国内已较普遍应用于临床。现将我们应用的52例进行总结如下。 一、操作: 应用苏州电子仪器厂SHB—Ⅰ食道心上房搏机,将食道电极经鼻孔送入食道,插入深度32～36cm,以食道导联心电图获得双相或高大正相P波为准。起搏电压30～35V,起搏脉冲宽度1.5ms,频率一般在60～130 Esophageal atrial pacing with simple, safe and so on, in clinical cardiac electrophysiology and treatment has an important role. China has been more commonly used in clinical. Now we apply the 52 cases are summarized as follows. First, the operation: The application of SHB-Ⅰ esophageal supraventricular pacemaker in Suzhou Electronic Instrument Factory, the esophageal electrodes into the esophagus through the nose, the depth of 32 ~ 36cm, the esophageal lead electrocardiogram bipolar or high positive phase P-wave prevail . Pacing voltage 30 ~ 35V, pacing pulse width 1.5ms, the frequency is generally 60 ~ 130
