Microvolt T-Wave Alternans Test Accurately Predicts Risk of Sudden Cardiac Arrest, Meta-Analysis Finds

Evidence from 13 clinical studies involving 6,000 heart patients and four additional papers published today support MTWA testing

 

 

The meta-analysis, conducted by a group led by Stefan Hohnloser, MD, FHRS, of the JW Goethe University Division of Cardiology in Frankfurt, Germany, assessed 13 MTWA clinical studies involving approximately 6,000 cardiac patients.

“The results demonstrate that MTWA testing is a consistently accurate predictor of sudden cardiac death and cardiac arrest in patients who do not already have implantable cardiac defibrillators (ICDs),” said Dr. Stefan Hohnloser. “These are the patients for whom MTWA testing is intended."

The meta-analysis authors also conclude that:
