Laboratory Findings
Laboratory studies in patients with atrial flutter include:
- Complete blood count is routinely done to look for anemia
- Differential count to look for elevated white cell count in infectious causes like pericarditis
- Thyroid function tests are done to look for hyperthyroidism, which is a potential cause of atrial flutter
- Blood gas analysis is done to look for hypoxia and carbonmonoxide poisoning
- Erythrocyte sedimentation rate
- Urinalysis
- Liver function tests
- Pre-warfarin coagulation screen (INR/aPTT)
