Explanation:
The first line of treatment for bradycardia with no adverse effects is atropine administration. Atropine is a medication that increases the heart rate by blocking the action of the vagus nerve, which slows down the heart rate. It is commonly used to treat bradycardia in emergency situations. Examples of other treatments for bradycardia include pacemakers and medications like epinephrine, but atropine is the first line of treatment.
