药丸电极是一种包藏在标准的药物胶囊里为病人易于吞食的特制电极。作者试图用这种电极作食管心房起搏,测定其对心房扑动(房扑)病人的疗效和耐受性。14例房扑病人,男11例,年龄25～65岁,女3例,26～72岁。电极为双极丸状,宽3mm,间距13mm,用一对细导线通过食管前置放大器连接至心电图机,病人吞食药丸电极后,胶囊迅速融化。根据最大的心房波来确定食管电极的最佳位置,然后将电极联接至恒流刺激器,先以高于心室率15～20次/min 行试验刺激,无心室夺获后以高于心房率10～20次/min 行心房起搏,刺激时间最长20秒,然后突然停止。如起
The pellet electrode is a special electrode housed in a standard drug capsule for easy patient ingestion. The authors attempted to use this electrode for esophageal atrial pacing and determine its efficacy and tolerability in patients with atrial flutter (atrial flutter). 14 cases of atrial flutter patients, 11 males, aged 25 to 65 years old, 3 females, 26 to 72 years old. Electrodes bipolar pellets, width 3mm, spacing 13mm, with a pair of thin wires through the esophageal preamplifier connected to the ECG machine, the patient swallowed pill electrodes, the capsule quickly melted. According to the largest atrial wave to determine the optimal esophageal electrode position, and then the electrode is connected to the constant current stimulator, first higher than the ventricular rate of 15 to 20 times / min line stimulation test, no ventricular seizure higher than the atrial rate 10 ~ 20 times / min atrial pacing, stimulation time up to 20 seconds, and then suddenly stopped. As of
