Authors' recommendations:
A meta-analysis and a number of large prospective studies have demonstrated the effectiveness of MTWA testing in predicting future arrhythmic events across a variety of patient populations. The test appears to be a useful method for identifying which patients with heart disease and left ventricular dysfunction are unlikely to receive benefit from ICD therapy. However, although the NPV of the test is high, there is still some concern surrounding the number of events occurring in patients who test MTWA negative, particularly given the nature of such events. Furthermore, the potential value of the MTWA test in clinical, economic and financial terms will be determined by the willingness of the clinician to act upon the MTWA test result, either alone or in combination with other prognostic information.
