In this study, changes in electroencephalogram (EEG) and the hemodynamic state during ventricular fibrillation or induced ventricular tachycardia are investigated.

Condition Intervention
Ventricular Fibrillation Ventricular Tachycardia Device: EEG

Study Type: Interventional

Further study details as provided by Heidelberg University:

Estimated Enrollment: 30
Detailed Description:
Patients with a high risk of malignant tachyarrhythmia are routinely investigated by programmed electrophysiological study (EPS). To investigate the hemodynamic effects of ventricular arrhythmia to cerebral circulation an EEG and transcranial ultrasound are conducted simultaneously during the EPS. Before and after the EPS a neuropsychological test and an investigation of a specific blood sample (Neuron Specific Enolase, NSE) is done.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All

Inclusion Criteria:

  • Age > 18 years
  • Positive agreement
  • EPS for primary and secondary prophylaxis of a malignant ventricular tachyarrhythmia:

    • primary prophylaxis: Brugada syndrome, long QT syndrome, cardiomyopathy, short QT syndrome
    • secondary prophylaxis: Multicenter Automatic Defibrillator Implantation Trial (MADIT) criteria, syncope, documented ventricular tachycardia

Exclusion Criteria:

  • Severe neurological deficit
  • Cardiopulmonary resuscitation
