Medical Therapy

Bradyarrhythmias are well controlled with pacemakers, while tachyarrhythmias respond well to medical therapy. However, because both bradyarrhythmias and tachyarrhythmias may be present, drugs to control tachyarrhythmia may exacerbate bradyarrhythmia. Therefore, a pacemaker is implanted before drug therapy is begun for the tachyarrhythmia.

Contraindicated medications

Sick sinus syndrome is considered an absolute contraindication to the use of the following medications:

• Adenosine
• Carvedilol
• Diltiazem
• Dronedarone
• Esmolol
• Fingolimod
• Metoprolol
• Nebivolol
• Propafenone
