title: Blood pressure dynamics during simulated ventricular tachycardia in patients after right ventricular outflow tract reconstruction mainly for tetralogy of Fallot compared with patients after ventricular septal defect closure.
abstract: We studied hemodynamic changes during simulated ventricular tachycardia using ventricular pacing. Hemodynamic deterioration during pacing is more significant in patients after right ventricular outflow tract reconstruction, especially in adults, than after closure of a ventricular septal defect. The cardiac autonomic nervous system has a significant impact on hemodynamics during simulated ventricular tachycardia.
