Abstract

Introduction. The use of concurrent, single lead electrocardiograph (ECG) recording, when performing a routine electroencephalograph (EEG), has been standard practice for many years. Previous studies have reported on the usefulness of concurrent EEG in assessing syncope and the detection of newly identified cardiac dysrhythmia but have relied on specialist cardiologist interpretation of the ECG trace. This study expands the understanding of concurrent ECG and provides demographic information regarding the incidence, nature of ECG changes and diagnostic utility of ECG interpretation, during routine EEGs, as evaluated by neurologists. Methods. A single center, retrospective study of routine concurrent EEG and ECG recordings was performed. All routine EEGs, performed within a 12 month period were analysed. Demographic data, underlying comorbidities, reasons for referral and ECG changes were assessed. Results. ECG abnormalities were identified in 147 (13.5%) of concurrent ECG/EEG routine recordings. The presence of ECG abnormalities was significantly associated with the reason for referral, namely being assessed for the evaluation of seizure activity and with increasing patient age. Thirty-eight patients (3.5%) had newly identified ECG abnormalities, of which atrial fibrillation (AF) (12 patients) and sinus bradycardia (9 patients) were the most common. Five patients (0.5%) had a change in their management consequent to the identified ECG changes. Conclusions. These findings support the value of neurologists' interpretation and need for ongoing concurrent ECGs, during routine EEG recordings. The study raises concern about the requesting clinician's response to the identification of newly diagnosed cardiac dysrhythmias.

进行脑电图时并发心电图的价值。
介绍。在进行常规脑电图(EEG)时,使用并发单导联心电图(ECG)记录已成为多年来的标准做法。先前的研究报道了并发脑电图在评估晕厥和检测新发现的心律失常方面的有用性,但依赖于专科心脏病专家对心电图痕迹的解释。这项研究扩大了对并发心电图的理解,并提供了关于发生率、ECG变化的性质和心电图解释的诊断效用的人口统计信息,在常规脑电图中,由神经科医生评估。方法。采用单中心回顾性研究,同时进行常规脑电图和心电图记录。分析12个月内所有常规脑电图。评估了人口统计数据、潜在合并症、转诊原因和心电图变化。结果。心电图异常147例(13.5%)。心电图异常的存在与转诊的原因显著相关,即评估癫痫活动和患者年龄的增加。38例(3.5%)患者新发现心电图异常,其中房颤(AF) 12例、窦性心动过缓(9例)最为常见。5名患者(0.5%)因心电图改变而改变了治疗方法。结论。这些发现支持了神经科医生的解释的价值,以及在常规脑电图记录期间持续并发心电图的必要性。这项研究引起了人们对临床医生对新诊断的心律失常的反应的关注。
