Holter Monitor Recordings in Patients with Asymptomatic Positive Exercise Thallium-201 Defects
Silent myocardial ischemia has been the subject of recent attention in the literature [1–5]. In spite of its clinical importance, the diagnostis of silent ischemia has remained unclear. While myocardial ischemia is usually accompanied by symptoms, asymptomatic episodes of ischemia have directed our diagnostic attention to the potential for laboratory diagnosis . The ease with which the electrocardiogram and Holter monitor can be obtained has led clinicians to view these tools as useful for the identification of episodes of silent ischemia. Unfortunately, ST- and T-wave abnormalities are nonspecific indicators of myocardial repolarization, thus compromising the value of these changes when they do occur.
