Episode notes
Approach ICU Arrhythmia Workup
- Start arrhythmia workup fresh postoperatively, considering surgical, volume, cardiac, or pulmonary causes.
- Obtain 12-lead ECG and full labs, assess hemodynamic stability, and review patient trend and history.
Prioritize Rate Control
- Prioritize rate control in postoperative atrial fibrillation to reduce tachycardia and help wean vasopressors.
- Use beta blockers or calcium channel blockers as first-line medications for rate control in stable patients.
Medications for Rate Control
- Use beta blockers first for rate control especially if patient was previously on them.
- Consider amiodarone cautiously if beta blockers insufficient, avoiding it early in postoperative patients.
