Quadripolar technology which was first to market and which has helped revolutionize pacing options for CRT is leveraged by the CRT-D pacing lead of Quartet and Quadra Assura. Heart failure patients can now be better managed through the second generation innovative CRT system that offers LV pacing at a preferred site through the use of ten different pacing configurations and four electrodes while minimizing lead stability compromise at the same time. Unlimited options offered by the Quadripolar technology are Less compromise on lead stability through greater basal pacing. According to studies, Improved outcomes and reverse LV remodeling seem to be associated with basal pacing. Common complications of pacing like phrenic nerve stiumulation and high thresholds of pacing are managed more effectively thus enabling less requirement for repositioning of lead and surgical revisions, One year shock management options and 98.5% patients are free from inappropriate shocks through Decision Programming and ShockGuard technology
