• sustained ventricular tachycardia
• 2nd or 3rd degree heart block
• prolonged pauses of > 3 seconds
  Possibly pathologic rhythms:
• brief runs of atrial fibrillation
• supraventricular tachycardia
• non- sustained ventricular tachycardia
• frequent in elderly without syncope or presyncope
• significant if symptoms accompany dysrhythmia
