Bipolar leads for left ventricular pacing (LVP) such as the newly available ACUITY™ or the standard EASYTRAK™ II and EASYTRAK™ III leads from GUIDANT in combination with suitable devices for cardiac resynchronization therapy (CRT) allow for the non-invasive programming of different Left Ventricular Pacing (LVP) configurations. Hence, this Electronic Repositioning (ER) may help physicians to overcome problems in cardiac resynchronization therapy (CRT) such as ineffective biventricular pacing, high Left Ventricular Pacing (LVP) thresholds and phrenic nerve stimulation (PNS) without the need for an additional patient's operation to reposition LV leads. The ERACE study it a multi-center, prospective, non-randomized clinical study to document and evaluate appropriate performance of GUIDANT's Electronic Repositioning™ in the clinical routine with respect to the following major aspects:
avoidance of PNS and low LVP thresholds (for low battery consumption and extended device longevity) in standard cardiac resynchronization therapy (CRT)
