Increased QT Dispersion Is Linked to Worse Outcomes in Patients Hospitalized for Out‐of‐Hospital Cardiac Arrest [PDF]
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Background The incidence and mortality of out‐of‐hospital cardiac arrest (OHCA) remains high, but predicting outcomes is challenging. Being able to better assess prognosis of hospitalized patients after return of spontaneous circulation would enable ...
