The Value of Concurrent Electrocardiography When Performing an Electroencephalograph

Area of Science:

• Neurology
• Cardiology
• Medical Diagnostics

Background:

• Concurrent electrocardiograph (ECG) and electroencephalograph (EEG) recording is standard practice.
• Previous studies focused on cardiologist interpretation of ECGs during EEGs.
• This study evaluates neurologist interpretation of concurrent ECGs during routine EEGs.

Purpose of the Study:

• To assess the incidence, nature, and diagnostic utility of ECG changes during routine EEGs, interpreted by neurologists.
• To provide demographic data on ECG abnormalities found during concurrent EEG/ECG recordings.
• To evaluate the impact of neurologist-interpreted ECG findings on patient management.

Main Methods:

• A single-center, retrospective study of routine concurrent EEG and ECG recordings.
• Analysis of demographic data, comorbidities, referral reasons, and ECG changes over a 12-month period.
• Assessment of ECG interpretation by neurologists.

Main Results:

• ECG abnormalities were found in 13.5% of concurrent recordings.
• Abnormalities were associated with seizure activity evaluation and increasing patient age.
• Newly identified cardiac dysrhythmias, including atrial fibrillation and sinus bradycardia, were noted in 3.5% of patients, leading to management changes in 0.5%.

Conclusions:

• Neurologist interpretation of concurrent ECGs during EEGs is valuable and supports their continued use.
• The study highlights the need for improved clinician response to newly diagnosed cardiac dysrhythmias identified during EEGs.
• Ongoing concurrent ECG monitoring during routine EEGs is recommended for comprehensive patient assessment.
