Role of sympathovagal balance in the initiation of idiopathic ventricular tachycardia originating from right ventricular outflow tract.


VT originating from the right ventricular outflow tract (RVOT) is prone to occur when sympathetic nervous activity is increased. beta-Blockade is, therefore, effective in suppressing this VT. The purpose of this study was to determine the role of sympathovagal balance assessed by heart rate variability (HRV) in the spontaneous initiation of repetitive… (More)
