case_images: Within three weeks, the AV and VV delays were automatically adjusted by the device on a weekly basis; the patient became asymptomatic while the SonR signal amplitude increased (Figure 1).

case_images: Figure 2 shows the SonR signal amplitude evolution during these two periods (before and after LV lead implantation): the amplitude increased while the patient's status improved after the successful LV lead implantation.

case_images: Figure 3 shows the decrease of the SonR signal amplitude that started concomitantly to AF and remained low as long as AF lasted.
