WebApr 14, 2024 · Or planned upgrade of an existing pacemaker or ICD to a biventricular pacing system (CRT-P or CRT-D), where the ECG is with sinus rhythm and a typical left bundle branch block or there has been> 90% right ventricular pacing from an existing pacemaker for at least 2 months prior to enrollment ... Typical left bundle branch block: QRS width > 130 ... WebSep 9, 2015 · Ventricular demand appears as a single pacemaker spike followed by a typical QRS pattern that is representative of a ventricular repolarization. This pattern often is associated with atrial fibrillation. Dual chamber sequential AV pacing may be identified on an EKG as a pacemaker spike prior to the P wave and QRS complex.
Webpacemaker implantation, intrinsic narrow QRS for EITHER of the following: RV pacing anticipated ≤ 40%, LVEF ≤ 35%, NYHA Class III-IV RV pacing anticipated > 40%, NYHA Class I,II, III-IV • Refractory NYHA Class III/IV heart failure < … WebIf adaptive BiV pacing is delivered, then BiV pacing will be 30 ms after the end of P-wave or 50 ms before intrinsic A-RVs interval, whichever is smaller. The interventricular pacing delay (VV timing) during BiV pacing is calculated based on A-RVs as well as RVs-QRS end intervals. The shortest VV interval will be selected to allow LV preactivation.
