Official title

Identifying Genetic Markers That Predict Microvolt T-wave Alternans Status and Arrhythmia Risk in Patients With Ischemic Heart Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The ABCD clinical study (ClinicalTrials.gov Identifier NCT00187291) was designed to determine if a T-Wave Alternans (TWA) test is equivalent to an Electrophysiology Study (EPS) in predicting life-threatening heart rhythms in patients with ischemic heart disease, left ventricular dysfunction, and non-sustained tachycardia. The purpose of the ABCD Genetic sub-study is to identify genetic markers that predict TWA status and arrhythmia risk in this same population.
