Figure 7 Sensitivity analysis, non-device costs. Input for each cost varied from 50% to 200% of baseline values. The x-axis represents the cost-advantage of the atrioventricular (dual-chamber) implantable cardioverter-defibrillator (AV-ICD) strategy over the single-chamber strategy. The vertical line represents the $3,000 cost advantage of the AV-ICD strategy assuming baseline values. At no variation of input values does the AV-ICD strategy become more expensive (cross zero).
