SCA Can be Detected Using Microvolt T-Wave Alternans
Sudden cardiac arrest (SCA) can be detected using Cambridge Heart’s Microvolt T-Wave Alternans (MTWA) diagnostic test, a cost-effective treadmill test can identify those at high or low risk. CThe test is said to be 1,000 times more sensitive than an ECG in detecting tiny heartbeat irregularities closely associated with SCA risk. MTWA is also a consistently accurate predictor of SCA, according to a 6,000 patient meta-analysis and four supporting studies recently published by Heart Rhythm Journal. Cambridge Heart’s MTWA is the only T-wave alternans test reimbursed by Medicare.
