In the Nuclear Cardiac worksheet, the following fields are calculated automatically. These calculated values automatically update when any of the source values are changed.
Field | Source Values | Calculation Logic |
|---|---|---|
Max APHR | Patient Age | 220 - Patient Age |
90% of Max APHR (Target) (or custom value instead of 90) | Max APHR | Max APHR × 0.9 Note: This calculation can be configured to use a custom value instead of 0.9. |
% of Max APHR
| Max APHR Max Achieved | (Max Achieved ÷ Max APHR) × 100 |
Duke Treadmill Score | Duration (min:sec) from Exercise section, Max ST Deviation, Angina Scale (0, 1, or 2) | Duration - (5 × Max ST Deviation) - (4 × Angina Scale) |
METs | last Grade and Speed with a BP or HR entry | (hc + vc + 3.5) ÷ 3.5 hc = (speed × 26.8 × 0.1) vc = [speed × 26.8 × 1.8 × (grade ÷ 100)] Note: METs will only be calculated for the following test types: Exercise Treadmill, Adenosine with Treadmill, or Regadenoson with Treadmill. The calculation will use the HR and BP from the last stage in which all values are documented. |
Double Product | Heart Rate (HR), Systolic Blood Pressure (SBP) from last stage with both entered (not Rest) | (HR) × (SBP) |
Studycast supports importing measurements to nuclear cardiac studies using XML files from nuclear post-processing software. Not all files have the same information. The table below shows which measurements each nuclear post-processing software shares.
Note: Studycast can automatically populate study data from Syntermed nuclear post-processing software.
