结论：增加左心室后负荷诱发室性心律失常，与左室空间不应期离散增加有关。
CONCLUSION: Ventricular arrhythmia induced by increasing afterload in LV related to increase of temporal dispersion of refractory period.

The relative refractory period, functional refractory period and effective refractory period (ERP) of right atrial, atrioventricular node and right ventricle were increased.
