to determine whether haemodynamic effective support of the failing heart can prevent spontaneous irreversible ventricular fibrillation ( ivf ) after experimental cardiogenic shock , 63 open chest dogs were assigned randomly into four groups -- two control groups ( combined heart failure -- chf ) and two mchss-treated ( combined heart failure and non-pulsatile bypass with intraaortic counterpulsation ) .
