IDIAQUEZ C, Juan; RIVERA T, Enzo; SANTIN M, Julia  y  GODOY F, Jaime. Bradycardia during epileptic seizures: Report of two patients. Rev. méd. Chile [online]. 2009, vol.137, n.3, pp. 401-404. ISSN 0034-9887.  http://dx.doi.org/10.4067/S0034-98872009000300012.

Cardiac rate and rhythm due to autonomic activation, may occur during epileptic seizures. They are probably a consequence of the spreading seizure activity to structures involved in the autonomic control of cardiac rhythm. Sinus tachycardia is the most frequent finding (90%). letal bradycardia is rare and Ufe threatening asystoles require cardiac pacemaker insertion. We report two patients with a right frontal seizure associated to bradycardia, during simultaneous EEG/ECG monitoring. Interictal autonomic function tests showed preserved sympathetic and cardiac vagal responses. Normal interictal autonomic function tests, suggested a transient failure of sympatho-vagal balance .
