Microvolt T-wave altemans

The most novel of the noninvasive techniques involves evaluation of microvolt T-wave altemans (MTWA). This noninvasive diagnostic approach detects minute changes in electrical activity in the T-wave as it alternates in shape, amplitude, and timing beat by beat A positive MTWA test has been linked to inducible (48-51) and spontaneous (57,58) maUgnant ventricular arrhythmias.
