Identifying a cardiac source of embolism

Where there is a confirmed diagnosis of a new ischaemic stroke / TIA the patient’s cardiac rhythm should be determined.

  • An ECG will determine the presence of an abnormal cardiac rhythm such as atrial fibrillation (AF)
  • Prolonged cardiac monitoring may be required for some patients
  • A patient in sinus rhythm would normally be prescribed antiplatelet drugs
  • A patient in AF or paroxysmal AF should be considered for  anticoagulant drugs
  • Where there is a risk of bleeding a patient in AF or paroxysmal AF may be prescribed antiplatelet drugs
