Final answer:
Symptomatic wide complex tachycardia is primarily treated with electrical cardioversion and antiarrhythmic medications like amiodarone. Adenosine can be used in certain cases for diagnosis or when the rhythm is believed to be supraventricular with aberrant conduction.
Step-by-step explanation:
The medical treatment for symptomatic wide complex tachycardia can involve several approaches. Electrical cardioversion is used in emergency situations to restore a normal heart rhythm when the patient is unstable. Antiarrhythmic medications, including amiodarone and procainamide, are often used to treat ventricular arrhythmias like wide complex tachycardia by modulating the heart's electrical conduction system. Although not a primary treatment for wide complex tachycardia, adenosine may be administered in certain cases of regular, monomorphic wide complex tachycardia to aid in the diagnosis or to treat when the rhythm is thought to be supraventricular in origin with aberrant conduction. The choice among these treatments should be based on clinical judgment and the specific characteristics of the patient's tachycardia.
