"Diagnostic tests in syncope patients are performed to assess the patient's prognosis and to tailor therapy. Exclusion of a cardiac cause is important and can mostly be done with simple tests including an ECG and echocardiogram. There is no ‘golden standard test' which provides a definite diagnosis, Therefore, several tests are used in common practice. The prognostic value, in terms of sensitivity and specificity, is discussed for three diagnostic tests : electrophysiologic testing, head-up tilt test and the ATP (Adenosine Tri-Phosphate) test. All of these tests have a value in the diagnostic evaluation, with their own limitations. The ECG at the time of syncope appears the best test, although it does not always provide a definite diagnosis. The Implantable Loop Recorder (ILR) seems a promising tool in various patient subgroups." |
