Outcomes
We collected data on in-hospital mortality as well the development of
hemodynamic compromise (HC) following ATA. To determine HC in those with
new-onset ATA, the maximum NE Eq doses of vasopressor recorded the hour
before the onset of ATA were compared with the maximum NE Eq dose of
vasopressors during the hour after the onset of these arrhythmias.
Participants were classified as having HC following ATA if their NE Eq
vasopressor dose requirement increased or if direct current
cardioversion was performed within one hour of acute arrhythmia onset.
