Final answer:
The initial treatment for complete heart block may involve urgent treatment with cardioversion or defibrillation for severe symptoms. In less severe cases, medications such as atropine or pacemakers may be used.
Step-by-step explanation:
The initial treatment for complete heart block depends on the severity of symptoms. In patients with severe symptoms, urgent treatment may involve controlled electric shock in the form of cardioversion or defibrillation.
In less severe cases, medications such as atropine or pacemakers may be used. Atropine is a medication that increases the heart rate, while pacemakers are small devices implanted in the chest that regulate the heart's electrical activity.
