title: Technical advances in the investigation of the cardiac patient.
abstract: Patients who never have experienced symptoms of heart failure or ischaemia but who demonstrate abnormalities have a much better prognosis than their symptomatic counterparts. At present the significance of some detected abnormalities is unknown: caution in interpreting these is advised and whenever possible an optimistic outlook should be given to the patient.
