Wicket Spikes - Benign Temporal Variant Misdiagnosed as Epilepsy

A 58-year-old woman is referred for EEG after a single unprovoked syncopal episode preceded by lightheadedness on standing. Cardiac workup including tilt-table testing suggests vasovagal syncope. During drowsy relaxation, the EEG shows brief runs of 8–10 Hz archiform activity over the left mid-temporal electrode (T3), with amplitude 80–150 microvolts appearing in bursts of 4–8 waves. Individual waveforms have a rounded configuration and do NOT disrupt background activity. The structure marked **A** in the diagram represents this activity. Which of the following is the MOST IMPORTANT clinical implication of correctly identifying this finding?
