Final answer:
Symptomatic bradycardia is treated by addressing the underlying cause, which may include medications or possibly a pacemaker if the condition is severe. Beta blockers are used to manage the condition but can also be a cause when overprescribed.
Step-by-step explanation:
Symptomatic bradycardia, a condition where the heart rate drops below 60 beats per minute (bradycardia), can be concerning if it results in symptoms like weakness, fatigue, or dizziness.
Treatment focuses on the underlying cause, which can range from metabolic disorders to electrolyte imbalances or cardiac issues such as SA or AV node abnormalities.
Oxygen supplementation is sometimes required. Various medications, including beta blockers and antiarrhythmic agents like procainamide, may be administered to manage heart rhythm.
However, overprescription of beta blockers can also lead to bradycardia. In cases of severe symptomatic bradycardia, a medical device such as a pacemaker may be implanted to maintain a regular heartbeat.
