WebSep 1, 2024 · CRT should be considered for patients with HF and LVEF ≤35% in NYHA class III or IV if they are in atrial fibrillation (AF) and have intrinsic QRS ≥130 ms, provided a strategy to ensure biventricular capture is in place. AV junction ablation should be added in the case of incomplete biventricular pacing (<90-95%) due to conducted AF. WebAberrant conduction occurs when the length of the cardiac cycle is changed without a compensatory change in the length of the refractory period. This is explained by the changes of the refractoriness in the His-Purkinje system related to changes in the RR interval.
