Interactions between disordered cardiac rhythm and abnormal cardiac hemodynamic function are well recognized. Demonatrations 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. With the development of newer and more potent antiarrhythmic agents, in conjunction with drugs that can improve the failing circulation, it is now possible to clarify these interrelationships and perhaps develop new strafegies for clinical management.
