  1. Class I – Patients with cardiac disease but without resulting limitation of
    physical activity. Ordinary physical activity does not cause undue fatigue,
    palpitation, dyspnea, or anginal pain.
  2. Class II – Patients with cardiac disease resulting in slight limitation of
    physical activity. They are comfortable at rest. Ordinary physical activity
    results in fatigue, palpitation, dyspnea, or anginal pain.
  3. Class III – Patients with cardiac disease resulting in marked limitation of
    physical activity. They are comfortable at rest. Less than ordinary activity
    causes fatigue, palpitation, dyspnea, or anginal pain.
  4. Class IV – Patients with cardiac disease resulting in inability to carry on
    any physical activity without discomfort. Symptoms of heart failure or
    the anginal syndrome may be present even at rest. If any physical activity
    is undertaken, discomfort increases.1
