Routine monitoring of a bipolar atrial electrogram (AEG) simultaneously with the electrocardiogram is a useful and safe clinical technique for the diagnosis of complex cardiac dysrhythmias. The large-amplitude A waves of the AEG can be more reliably identified than the corresponding low-amplitude p waves of the electrocardiogram. Epicardial wires placed during cardiac surgery, catheter-mounted endocardial electrodes, and esophageal electrodes can all be used for routine AEG monitoring. A multipurpose pulmonary arterial catheter with a pair of electrodes, and esophageal electrodes can all be used for routine AEG monitoring. A multipurpose pulmonary arterial catheter with a pair of electrodes mounted on the proximal shaft can be used for combined AEG and hemodynamic monitoring. The equipment needed for AEG monitoring and recording consists of an additional bedside amplifier with 12- to 100-Hz band-pass filter, a dual-channel display scope, and a dual-channel strip chart recorder. Care must be used to keep the atrial electrodes electrically isolated for patient safety. In addition to enhancing the diagnosis and management of dysrhythmias, recording an AEG provides a signal that is suitable for automatic processing.
双极心房电图（AEG）与心电图同时进行常规监测，是诊断复杂心律失常的一种有用且安全的临床技术。与心电图中相应的低振幅P波相比，AEG的高振幅A波能更可靠地识别。心脏手术期间放置的心外膜导线、导管式心内膜电极和食管电极均可用于AEG常规监测。带有一对电极的多用途肺动脉导管和食管电极均可用于AEG常规监测。近端轴上装有一对电极的多用途肺动脉导管可用于AEG和血流动力学联合监测。AEG监测和记录所需的设备包括一个带有12至100赫兹带通滤波器的床边放大器、一个双通道显示示波器和一个双通道条形图记录仪。为了患者安全，必须小心使心房电极保持电隔离。除了加强心律失常的诊断和管理外，记录AEG还能提供一个适合自动处理的信号。
