Microvolt T-Wave Alternans and Risk of VT Events
Despite a modest association with VTE, the results of spectrally derived MTWA testing do not sufficiently modify risk assessment of VTE to change clinical decisions, particularly if conventional risk markers such as reduced EF indicate an increased pretest risk. Based on current evidence, routine incorporation of MTWA results into clinical decision making regarding ICD therapy is not warranted.
