demonstrations of this relationship include the relationship between prognostic significance of ventricular ectopy and left ventricular ejection fraction , impairment of ventricular function in association with loss of atrial systole in disease states , increased risk of potentially lethal arrhythmias in the myopathic ventricle , and the evolution of advanced grades of ventricular arrhythmias in acute heart failure .
