WebJun 28, 2024 · RV lead location is assessed by fluoroscopy during implantation, ... This position is not good for stability and chronic pacing threshold since movements of the tricuspid valve and deep respiration can pull on the lead. RV apical pacing is associated with ventricular desynchronization, adverse remodeling, and pacing-induced cardiomyopathy. ... WebFeb 14, 2012 · In one patient without a pacing indication, sensing was obtained from the MCV lead; in this position, the R-wave sensing was excellent and capture threshold acceptable (2.8 V at 0.5 ms; diaphragmatic stimulation only occurred at an output of 7.5 V at 0.5 ms).
