Webtricular pacing lead impedance had increased from 480 to .3000 V (Figure 1), whereas the RV and superior vena cava shock coil impedance had remained nearly unchanged. In addition, the P-wave amplitude and atrial pacing impedance were within the normal ranges. Neither the ventricular nor the atrial lead appeared abnormal on the chest roentgen-ogram. WebDec 19, 2024 · Defibrillation impedance (also termed shock or HV impedance) can be measured in two different ways: either through a high output therapy—termed true shock …
Biventricular Pacing Versus Right Ventricular Pacing in Patients ...
WebClassically for CRT, and especially in CRT-D, the RV lead is placed at the RV apex. Lead positioning may significantly influence the quality of CRT and thus the outcome of the patients. WebThe Active Can ™ /SVC Coil parameter specifies the electrodes used for defibrillation and cardioversion pulses. Either the Active Can or the SVC coil can be turned off to noninvasively troubleshoot the ICD shock vectors in … the work wife parents guide
RV lead low impedence and insulation fracture
Web1) The RV pacing lead impedance measurement for either polarity is less than 50% or greater than 175% of the baseline impedance. The baseline measurement is the median … Webbackup support. Then the lead was re-implanted in the septal area. Fig. 2. Multi-detector CT scan images. A, Distal portion of the lead (dotted circle) is obs erved in the 3D reconstruction image. B, Arrowheads indicate the pacemaker lead penetrating RV apical myocardium and extending to anterior chest wall. LV, left ventricle; RV, right ventricle. WebRV lead impedance was lower with RV pacing (p = 0.047), but no significant differences were observed in impedance across other CRT leads. Conclusions: This study supports turning off LV lead pacing in LVAD patients with CRT.
