Benign; generally does not require any treatment or additional workup
Treat hypoxia/drug toxicity if existing
Correct electrolyte imbalances, particularly magnesium, calcium, potassium
Acute ischemia/infarction:
Complex ectopy frequently seen after patient receives thrombolytics
1st line are β-blockers, options below:
Acute MI: Metoprolol 5mg IV q2 min for x3 doses, then PO metoprolol 50mg q6hrs for 2 days, followed by maintenance of 100mg bid
Post-MI: Atenolol 5mg IV over 5 min, then repeat in 10 min, then PO atenolol 50mg q12hrs for 7 days post-MI
