Activities of Daily Living and Outcomes in Patients with Advanced Heart Failure.

Background: Functional debility is associated with worse outcomes in the general heart failure population, but the prevalence of difficulty with activities of daily living and clinical significance once patients develop advanced heart failure requires further examination.

Methods: This was a population-based, retrospective cohort study of Olmsted County, Minnesota adults with advanced heart failure from 2007-2018. Difficulty with 9 activities of daily living was assessed by questionnaire.

Wide complex tachycardia discrimination tool improves physicians' diagnostic accuracy.

Background: Timely and accurate discrimination of wide complex tachycardias (WCTs) into ventricular tachycardia (VT) or supraventricular WCT (SWCT) is critically important. Previously we developed and validated an automated VT Prediction Model that provides a VT probability estimate using the paired WCT and baseline 12-lead ECGs. Whether this model improves physicians' diagnostic accuracy has not been evaluated.
