title: Corrections.
abstract: In the April article by Cooper, “Biventricular Pacemakers in Patients With Heart Failure” (Critical Care Nurse. 2015; 35[2]:20-28), there was an error referring to right and left atrial chambers on page 25. The last full sentence in the first column on this page should read: “When biventricular pacemakers were first implanted, it was not always evident that both right and left ventricular chambers were being paced as there was no programmed delay between right and left ventricular pacing.”
