The Ellipse ICD and #8217 provides an excellent balance between the thinness and the footprint. It is the smallest device with high energy. This uses a profile with 30cc small VR DF4 model and 12mm thin with 36 J energy delivery and header with a unique angle. Shock management feature is available in VRDF4 model. It is predicted by the decision TX and #174 that 98.5% of sufferers will be free of incorrect shocks and #8212 with the help of shock guard and #174 without sensitivity compromise. Shock guard technology expands to the algorithm of RV lead noise discrimination and secure sense and #8482 and helps in differentiating the lead noise from VFVT. The detection of clinical VF is 1100%.
