Summary:
The purpose of this prospective study is to show a technique for recording electroencephalographic activity via an endovascular approach in presurgical evaluation of epileptic patients. Technical aspects and insertion strategy are outlined. Advantages of intra-arterial electroencephalography have been demonstrated. It is a semi-invasive procedure that provides information in temporal lobe and extratemporal epilepsy. It allows a dynamic electroencephalographic recording and patient tolerance is excellent. Risks are practically absent. Disadvantages are: in comparison to ovale electrodes, chronic and multicontact recording is not possible and the recording is only intercritical.

An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.
