| Popis: | BACKGROUND With extraction of cardiovascular implantable electronic devices (CIED) increasingly necessitated, various studies have contemplated to investigate clinical predictors for its success and complications. Intrinsic parameters of CIED leads have been studied less extensively and are the foci of this study. METHODS Three major pacemaker manufacturers accepted invitation. Leads then underwent tensile test in vitro with their composite tensile strength (TS) compared. Mechanism of yielding, under tensile stress, was also observed among them. RESULTS All pacing leads, participated in this study, surpassed requirement of European Standard EN 45502-2-1. Boston Scientific's FINELINE II STEROX 4456/52 cm (Boston Scientific Corp., St. Paul, MN, USA) and Medtronic's CAPSURE SENSE 4074/52 cm (Medtronic, Minneapolis, MN, USA) showed similar composite TS and both were stronger compared with St. Jude Medical's ISOFLEX OPTIM 1948/52 cm (P |
