A) Graph showing right ventricular (RV) impedance trend over 80 week period. B) Real-time tracing at 25mm/s, showing EGMs. The source of EGM1, EGM2 (wavelet), EGM3 in the tracings are RV tip to RV ring, can to RV coil, and RVtip to RVcoil, respectively. (EGM–electrogram, Vs – sensed ventricular complex, Vp-paced ventricular complex, RV – right ventricle).
