The T-wave alternans test is especially important, because it can identify who's at risk for sudden cardiac death," says Cleveland Clinic cardiologist Patrick Tchou, MD.
Microvolt T-wave alternans test done at baseline was abnormal in 66% of patients, and the two-year event rate was 15% and 2.
The T-wave alternans test emerges as a good predictor of ventricular malignant arrhythmias permitting the selection of low risk heart failure patients (independent of etiology: ischemic or idiopathic), who may not benefit of ICD implantation by standard criteria, due to high negative predictive values in most studies.
About the Cambridge Heart Microvolt T-Wave Alternans Test
The Cambridge Heart Microvolt T-Wave Alternans Test measures extremely subtle beat-to-beat fluctuations in a person's heartbeat called T-wave alternans.
Taking the alternans test is similar to getting the standard stress test except that a patient is hooked up to a few extra leads.
Microvolt T-Wave Alternans Test Identifies Latent Risk for Sudden Cardiac Arrest
Among the entire study population, only one patient with an indeterminate or negative T-wave alternans test died.
Moreover, an abnormal T-wave alternans test was associated with a 7.
Therefore, all eyes are now on two large, more definitive ongoing prospective randomized interventional ICD trials that incorporate the only Food and Drug Administration-approved T-wave alternans test, developed by Cambridge Heart Inc.
The T-Wave Alternans test is included in the Guideline for Management of Patients with Ventricular Arrhythmias and the Prevention of Sudden Cardiac Death jointly developed by the American College of Cardiology (ACC), The American Heart Association (AHA) and the European Society of Cardiology (ESC).
The Cambridge Heart Microvolt T-Wave Alternans Test measures a specific extremely subtle pattern of beat-to-beat fluctuations in a person's electrocardiogram.
