Microvolt T-Wave Alternans to Identify Risk of Ventricular Arrhythmias and Sudden Cardiac Death

Record ID 32010000898
English
Authors' objectives:

Microvolt T-wave alternans (MTWA) testing is proposed as a screening tool for detecting patients who are at risk for ventricular tachyarrhythmia and sudden cardiac death in order to identify patients most likely to benefit from an inserted implantable cardioverter-defibrillator (ICD). MTWA is a subtle, beat-to-beat variability in the morphology, amplitude, and/or polarity of the T-wave portion of the heartbeat. It is detected by electrocardiographic (ECG) studies that involve specialized highresolution electrodes and computer analysis. MTWA testing requires gradual elevation of the heart rate, which is achieved by exercise, drugs, or, in some cases, atrial and ventricular pacing.
