The study was undertaken to determine the feasibility of obtaining esophageal ECGs using resterilized 3F temporary pacing balloon-inflated electrodes in place of the more expensive pill-electrode and its associated expensive preamplifier.
Tests were conducted in the emergency department and ICU.
Subjects were 12 acutely ill patients for whom standard 12-lead surface ECGs were insufficient to afford accurate, immediate arrhythmia diagnosis.
Reasonable quality esophageal ECGs were obtained by use of the electrodes, generally with minimal patient discomfort. The test never required more than ten minutes. Of the 12 patients who participated in this preliminary study, esophageal ECGs enabled definitive diagnoses to be made in ten cases.
The use of resterilized temporary pacing balloon-inflated electrodes enables esophageal ECGs to be obtained in an acute care setting.
本研究旨在确定使用经过再消毒的3F临时起搏球囊充气电极代替更昂贵的药丸电极及其相关的昂贵前置放大器来获取食管心电图的可行性。
在急诊科和重症监护病房进行测试。
研究对象为12名急性病患者，其标准12导联体表心电图不足以进行准确、即时的心律失常诊断。
使用这些电极获得了质量合理的食管心电图，患者通常只有轻微不适。该测试从未超过十分钟。在参与这项初步研究的12名患者中，食管心电图使10例患者得以明确诊断。
使用经过再消毒的临时起搏球囊充气电极能够在急性护理环境中获取食管心电图。
