Associated with higher mortality and longer stays in surgical ICU patients; hypothesis-generating for causality versus marker of illness severity.
Does the development of new-onset atrial arrhythmias increase mortality and length of stay in surgical ICU patients following major noncardiothoracic surgery?
New-onset atrial arrhythmias after major noncardiothoracic surgery are associated with increased mortality and longer hospital stays, serving as markers of morbidity rather than direct causes of death.
