Final answer:
The recommended therapy for bradycardia caused by a complete heart block or abnormal sinus node function is a pacemaker.
Step-by-step explanation:
Treatment for Bradycardia
If bradycardia is the result of a complete heart block or an abnormal sinus node function, the recommended therapy is a pacemaker.
A pacemaker is a small device that is surgically implanted in the chest to help regulate the heart's electrical activity. It delivers electrical impulses to the heart muscle, ensuring that the heart continues to contract and pump blood effectively.
Pacemakers can be programmed to stimulate the heart temporarily upon demand or on a continuous basis, as per the cardiologist's instructions.
