    Continuous ambulatory electroencephalography/electrocardiography (EEG/ECG) monitoring accurately diagnosed cardiogenic syncope. This method aids in differentiating syncope from seizures by analyzing simultaneous EEG/ECG data.

    Area of Science:

    • Neurology
    • Cardiology
    • Medical Instrumentation

    Background:

    • Syncope diagnosis can be challenging, often requiring differentiation from seizures.
    • Continuous ambulatory monitoring offers a potential solution for identifying the origin of recurrent syncope.

    Observation:

    • A patient with recurrent syncope underwent simultaneous electroencephalography/electrocardiography (EEG/ECG) monitoring using a continuous ambulatory cassette recorder.
    • The recording captured a spontaneous episode, revealing clear electrocardiographic abnormalities indicative of a cardiac origin.

    Findings:

    • Simultaneous EEG/ECG monitoring successfully identified the cardiogenic origin of the patient's syncope.
    • The study highlights the utility of this technique in the differential diagnosis of syncope and seizures.

    Implications:

    • ECG abnormalities during an event suggest a cardiogenic cause, warranting cardiac investigation.
    • Primary epileptiform EEG activity indicates a neurologic cause, necessitating neurological workup.
    • Non-epileptiform EEG slowing without ECG changes suggests non-cardiac syncope (e.g., hypotension, hypoglycemia).
