Cambridge Heart's Micro-V Alternans SensorsCambridge Heart’s proprietary Micro-V Alternans Sensors are designed to minimize noise and artifact. The multi-segment sensors allow the recording of up to four ECG signals from the same anatomical site. An adaptive noise reduction algorithm combines these signals, along with impedance and respiratory signals, to create an enhanced ECG.

Micro-V Alternans Sensors are available in pouches or as part of self-contained Test Kits that include all disposables required for MTWA testing including:

• MTWA Test kit 7 Micro-V Alternans Sensors
• 7 Standard Electrodes
• Razor
