Myocardial electrical impedance as a predictor of the quality of RF-induced linear lesions.

Production of complete (i.e. continuous and transmural) cardiac lesions by radiofrequency (RF) ablation can cure certain cardiac arrhythmias.

Heart rate variability during interictal epileptiform discharges.

Rationale: Seizures may produce a variety of autonomic alterations. These alterations may occur due to evoked autonomic reflexes or as a direct cortical effect on autonomic control. In animal studies, lock step phenomena of interictal discharges to autonomic output have been repeatedly documented.
