lv leads LV lead threshold management according to manufacturer. Fig. 1 Legend: Panel A: LV automatic threshold test for Medtronic devices (Vector Express), displaying loss of capture with intrinsic RV conduction. The channels displayed are: EGM 1 = atrial channel; ECG = the “large” RV dipole (coil to can) with A-V markers; EGM 3 = the “LV cathode .Markedly increased LV voltages: huge precordial R and S waves that overlap with the adjacent leads (SV2 + RV6 >> 35 mm). R-wave peak time > 50 ms in V5-6 with associated QRS broadening. LV strain pattern with .
Quartet Quadripolar LV Lead More pacing flexibility without compromising lead stability. Built on the proven QuickFlex™ µ lead platform, the Quartet™ quadripolar LV lead offers superb deliverability with exceptional stability and performance. Studies reflect an implant success rate averaging approximately 97%. 1,2 The LV lead position was assessed in 799 patients by means of coronary venograms and chest x-rays recorded at the time of device implantation. The LV lead location was classified along the short axis into an anterior, lateral, or posterior position and along the long axis into a basal, midventricular, or apical region.
lv leads However, LV epicardial lead placement is associated with increased rates of complications such as renal insufficiency and infections. 5 With the advancements made in tools and techniques for LV lead delivery, the implanting electrophysiologist now has a variety of approaches to adopt when encountering challenging LV lead implants to .
