Figure 3 Electrocardiogram during left ventricular (LV) pacing, showing fusion at AV1 and AV2 but not at AV3 and AV4. The right ventricular (RV) electrogram (EGM) is now changing when AV1 is programmed to AV2 and an additional change is noticed from AV2 to AV3 and AV4. The change from AV1 to AV2 is determined by the degree of fusion and from AV2 to AV3 by the complete loss of fusion.
