The VT Prediction Model: A simplified means to differentiate wide complex tachycardias.

abstract：INTRODUCTION:Previous studies suggest that class III antiarrhythmic drugs are more effective in reentrant arrhythmias because they prolong refractoriness (ERP) and wavelength and reduce dispersion of refractoriness compared to Class IA antiarrhythmic drugs, which slow conduction velocity (CV) in addition to their effec...
