Key result
Averaging the results of stepping down to the first failure and stepping up to the first success yielded lower total error in estimating the defibrillation threshold than either method alone.
Why the study?
Does a combined step-down and step-up averaging method reduce total error in determining defibrillation threshold compared to single-direction stepping methods?

Does a combined step-down and step-up averaging method reduce total error in determining defibrillation threshold compared to single-direction stepping methods?
Averaging the results of step-down and step-up methods provides a more accurate estimation of the true defibrillation threshold than either method alone.
Church et al. (1988) studied Fibrillation. Method 3 (averaging step-down and step-up methods) vs. Method 1 (step-down) and Method 2 (step-up) was evaluated on Total error in estimating the true defibrillation threshold. Averaging the results of stepping down to the first failure and stepping up to the first success yielded lower total error in estimating the defibrillation threshold than either method alone.
