• An arrhythmia is a change in the heart’s normal rate or rhythm.
  •  When an arrhythmia occurs repeatedly over time or causes symptoms such as
    palpitations, lightheadedness, fainting (syncope), shortness of breath, or chest pain, it
    requires treatment.
  • Antiarrhythmic drug treatment is designed to suppress arrhythmias by treating the
    underlying cause of arrhythmia, to prevent conditions that contribute to arrhythmias, and
    to manage arrhythmia symptoms.
  •  Common medications used to treat arrhythmias include a category of drugs referred to
    as antiarrhythmic agents, beta-blockers, calcium channel blockers, and digitalis.
