Sinus bradycardia during hypothermia in comatose survivors of out-of-hospital cardiac arrest - A new early marker of favorable outcome?

摘要

Background: Bradycardia is a common finding in patients undergoing therapeutic hypothermia (TH) following out-of-hospital cardiac arrest (OHCA), presumably as a normal physiological response to low body temperature. We hypothesized that a normal physiological response with sinus bradycardia (SB) indicates less neurological damage and therefore would be associated with lower mortality.
