Official Title

VNS Therapy Automatic Magnet Mode Outcomes Study in Epilepsy Patients Exhibiting Ictal Tachycardia

Eligibility Criteria

Ages Eligible for Study: Older than 12 Years
Sexes Eligible for Study: All
Accepts Healthy Volunteers: No
Inclusion Criteria:
  1. - Patients with a clinical diagnosis of medically refractory epilepsy with partial onset seizures suitable for implantation with the VNS Therapy System. - Patients willing to undergo an EMU evaluation for a period of at least three days with activation of the AMM feature during that time. - Patients must be at least 12 years old. - Patients must be in good general health and ambulatory. - Patient or guardian must be willing and able to complete informed consent/assent.
Exclusion Criteria:
  1. - Patients have had a bilateral or left cervical vagotomy. - Patients currently using, or are expected to use, short-wave diathermy, microwave diathermy, or therapeutic ultrasound diathermy. - A VNS Therapy System implant would (in the investigator's judgment) pose an unacceptable surgical or medical risk for the patient. - Patients expected to require full body magnetic resonance imaging (MRI). - Patients have a history of implantation of the VNS Therapy. - Patients with an IQ known or estimated to be < 70, history of depression requiring hospitalization, or suicidality as defined by DSM IV-TR that in the investigator's judgment would pose an unacceptable risk for the patient or prevent the patient's successful completion of the study. - Patients with a history of status epilepticus within 1 year of study enrollment. - Patients with known clinically meaningful cardiovascular arrhythmias as well as patients with clinically meaningful cardiovascular arrhythmias determined by a 24-hour Holter recording obtained during the baseline period. - Patients dependent on alcohol or narcotic drugs as defined by DSM IV-TR within the past 2 years. - Patients with a history of psychogenic non-epileptic seizures. - Women who are pregnant. Women of childbearing age must take a pregnancy test and agree to use an approved method of contraception during the study. - Patients currently enrolled in another investigational study.
