Acoustic intensity. The acoustic intensity of the transmitter when placed onto the viable intercostal space (ICS) was modeled. A transmitter was placed onto a 3-dimensional reconstruction of the rib cage, and the corresponding acoustic intensity was shown on a 16-segment bull’s-eye plot. This patient had 3 available ICSs. White areas had no power coverage, and blue areas had the greatest acoustic intensity likely to yield reliable biventricular pacing. If the target segment was basal anterolateral, then the sixth ICS should not be used, as this would not provide biventricular pacing.
