Impact of Beta-blockers Use on Ventricular Arrhythmias and ICD Shocks in Patients on Long-Term Inotropic Therapy

Purpose null Continuous infusion of inotropes is increasingly used in patients with end-stage heart failure who are being discharged from the hospital. However, Dobutamine and Milrinone are both known to be arrhythmogenic agents. Because Milrinone does not act through the beta-adrenergic system, it may allow for the cautious addition of beta-blockers (BB). We therefore sought to compare the impact of BB use is these patients on ventricular...
