PHASE I - Detection
The DETECTION phase filters the subcutaneous (S ECG) signal and generates detections for further analysis. A variety of profiles are used for detection of signals, including the new SMART Pass filter which is used to further reduce cardiac oversensing.
PHASE II - Certification
The CERTIFICATION phase analyses the detected events and classifies them as cardiac or noise. Four separate algorithms are used to prevent oversensing and ensure an accurate heart rate.
PHASE III - Therapy Decision
During the Therapy Decision phase, the INSIGHT algorithm discriminates between treatable and other high-rate events such as AF, sinus tachycardia, and other SVTs, helping to avoid inappropriate therapy. The Conditional and Shock Zone settings are programmable.
INSIGHTTM with Smart Pass Technology
- The SMART Pass feature activates an additional high-pass filter designed to reduce oversensing while still maintaining an appropriate sensing margin.1
- SMART Pass is only applied in the sensing path, while the morphology is unchanged.1
- In one study SMART Pass technology reduced T-wave oversensing (TWOS) by 82% compared to the Gen 1 S-ICD and 71% compared to the EMBLEM S-ICD2*.
