Objective: 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.  Methods: 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 \u2018arrhythmia, tachycardia, bradycardia, atrial fibrillation, extrasystole\u2019 to evaluate the neurologist interpretation.  Results: Overall, 478 routine EEG recordings were scanned. The mean age of the patients was 42.8\u00b119.8 (16\u201395), 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%).  Conclusions: 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.<\/jats:p>","DOI":"10.1590\/0004-282x20200105","type":"journal-article","created":{"date-parts":[[2021,1,10]],"date-time":"2021-01-10T08:17:53Z","timestamp":1610266673000},"page":"15-21","source":"Crossref","is-referenced-by-count":4,"title":["Simultaneous
