Treatment of Bradycardia

Bradycardia, also known as slow heart rate, typically does not require specific treatment when it is sinus bradycardia; management primarily focuses on addressing the underlying cause. However, if patients exhibit prominent symptoms such as dizziness, along with angina pectoris, heart failure, or central nervous system dysfunction—and have a heart rate below 40 beats per minute—pharmacologic interventions such as atropine administration or sublingual isoproterenol may be used to increase heart rate. In severe cases, pacemaker therapy may be indicated.
