The importance of simultaneous 2-lead electrocardiogram (ECG) recording during routine electroencephalogram (EEG) has been reported several times on clinical grounds.
To investigate arrhythmia rates detected by simultaneous 2-lead ECG in our patient sample undergoing routine EEG. Remarkably, we sought to assess the possible expansion of results with a more experienced interpretation of simultaneous ECG.
Simultaneous 2-lead ECG recordings during routine EEG, performed between January and March, 2016, have been retrospectively analyzed by a cardiology specialist. In addition, EEG reports were screened with the keywords 'arrhythmia, tachycardia, bradycardia, atrial fibrillation, extrasystole' to evaluate the neurologist interpretation.
Overall, 478 routine EEG recordings were scanned. The mean age of the patients was 42.8±19.8 (16-95), with a sex ratio of 264/214 (F/M). In 80 (17%) patients, findings compatible with arrhythmia were identified on simultaneous ECG after a cardiologist's evaluation. The detected arrhythmia subtypes were: ventricular extrasystole (n=27; 5.6%), supraventricular extrasystole (n=23; 4.8%), tachycardia (n=9; 1.8%), prolonged QRS duration (n=7; 8.7%), atrial fibrillation (n=6; 1.2%), and block (n=6; 1.2%). On the other hand, keywords related to arrhythmia were present in 45 (9.4%) of EEG reports. The reported statements were tachycardia (3.3%), arrhythmia (2.5%), bradycardia (2.1%), and extrasystole (1.5%).
A considerably high rate of arrhythmia cases was determined on simultaneous ECG during routine EEG after being interpreted by a cardiologist. However, the screening results of EEG reports revealed relatively low arrhythmia rates. These results suggest that the detection rates of ECG abnormalities during routine EEG may be potentially improved.
在临床实践中，已经多次报道了在常规脑电图（EEG）期间同时记录双导联心电图（ECG）的重要性。
调查我们的常规 EEG 患者样本中通过同时双导联 ECG 检测到的心律失常率。值得注意的是，我们试图通过更有经验的同时 ECG 解释来评估结果的可能扩展。
由心脏病专家对 2016 年 1 月至 3 月期间进行的常规 EEG 期间的同时双导联 ECG 记录进行回顾性分析。此外，通过关键词“心律失常、心动过速、心动过缓、心房颤动、期外收缩”筛选 EEG 报告，以评估神经科医生的解释。
总共扫描了 478 次常规 EEG 记录。患者的平均年龄为 42.8±19.8（16-95），男女比例为 264/214（F/M）。在 80 名（17%）患者中，经过心脏病专家评估，在同时 ECG 上发现了与心律失常相符的发现。检测到的心律失常亚型为：室性期外收缩（n=27；5.6%）、室上性期外收缩（n=23；4.8%）、心动过速（n=9；1.8%）、QRS 时限延长（n=7；8.7%）、心房颤动（n=6；1.2%）和阻滞（n=6；1.2%）。另一方面，EEG 报告中存在与心律失常相关的关键字。报告的内容为心动过速（3.3%）、心律失常（2.5%）、心动过缓（2.1%）和期外收缩（1.5%）。
在心脏病专家解释后，通过同时 ECG 在常规 EEG 期间确定了相当高的心律失常病例率。然而，EEG 报告的筛选结果显示心律失常率相对较低。这些结果表明，常规 EEG 期间心电图异常的检测率可能会有所提高。
