The baseline electrocardiogram (ECG) is less informative in neurally mediated syncope (NMS) than in arrhythmic syncope. However, some of the ECG patterns present in NMS can have diagnostic and prognostic value in such patients. Electrocardiographic documentation of a syncopal spell and thus identification of the ECG changes can be performed during tilt table test (TTT) or during prolonged ECG monitoring. This work reviews the specific ECG patterns in NMS, which are primarily related to the cardioinhibitory reflex. In addition, there are other ECG findings present in patients with NMS that are being analyzed, such as increased heart rate variability as well as specific QRS voltage patterns. In addition to the diagnostic and prognostic value, these ECG patterns in NMS may help improving the selection of patients for pacemaker implant.
基础心电图（ECG）在神经介导性晕厥（NMS）中不如心律失常性晕厥中信息丰富。然而，NMS 中存在的一些 ECG 模式在这些患者中有诊断和预后价值。在倾斜台试验（TTT）或长时间心电图监测期间，可以对晕厥发作进行心电图记录，从而识别 ECG 变化。本文回顾了 NMS 中的特定 ECG 模式，这些模式主要与心脏抑制反射有关。此外，NMS 患者还存在其他正在分析的 ECG 发现，例如心率变异性增加以及特定的 QRS 电压模式。除了诊断和预后价值外，NMS 中的这些 ECG 模式还有助于改善对起搏器植入患者的选择。
