The last generation devices, including INTENSIA, PARADYM, PARADYM RF and PARADYM 2 can be connected to unipolar or bipolar LV leads. In a unipolar, a single Distal LV à Proximal RV vector is available. In a bipolar configuration, 3 vectors are available, including a) Distal à Proximal LV, b) Distal LV à Proximal RV, and c) Proximal LV à to RV coil.
By the end of year 2015, the next generation of devices will offer 6 LV vectors with a bipolar IS-1 lead and 14 vectors with a quadripolar IS-4 lead.
