Microvolt T-Wave Alternans Testing
Procedure Description
Microvolt T-Wave Alternans testing identifies patients at risk of life-threatening heart rhythm disturbances. "T-Wave" testing will enable your physician to determine if you have a specific underlying electrical disorder that may put you at risk for sudden cardiac death. The test requires a mild elevation of you heart rate for a brief period of time. At VCC this is done using the treadmill. As with any treadmill test, excellent contact between your chest and the electrodes is imperative. Since Microvolt T-Wave Alternans testing analyzes smaller signals however, the chest prep is slightly more vigorous. The exercise portion of the test will last approximately 8-10 minutes. Information about your heart is gathered before, during and after the test.
