- evaluate and treat possible aggravating factors (e.g. ischemia, electrolyte disturbance, transvenous catheter in right ventricle, elevated sympathetic tone, hyperthyrodism, hypoxemia, acid/base distrubance, drugs)
- consider B-blocking agents if not contraindicated; other antiarrhythmic agents should be avoided
- admit for further evaluation, particularly to identify those who have structural heart disease and low ejection fraction, as this subset may benefit from an ICD
