Once a systematic deviation is identified, the deviating timepoint is corrected and the trend re-smoothed to calculate new deviations.
The balloon inflations that produced the greatest extent of ST-segment deviation were identified for each lead ("maximally ischemic periods").
Mean, range and standard deviation were identified in economic data.
The type of deviations and the reasons for them were examined and baseline factors associated with deviation were identified.
Points on a plot that lie outside a chosen multiple of the standard deviation are identified by colour.
Within each of these selected windows individual spikes with amplitudes greater than five times the epoch standard deviation were identified.
A further subgroup of critical deviations was identified as irretrievable critical deviations, where a patient completed the journey and was discharged.
In the third step, four of the ten deviations are identified by means of the link geometry.
In the first and second steps, after performing two measurements, six out of ten deviations are identified by means of an observation equation.
As the surgeon performs these tasks, any occurrence of errors, lack of clarity in the documented steps, necessary deviations are identified and documented.
