Cardiology Flashcards
CABG waiting period
Minimum — 3 months regardless of type of CABG surgery performed
Ejection fraction minimum
An LVEF greater than or equal to 40%.
Stable angina waiting period
Minimum — 3 months with no rest angina or change in angina pattern
Maximum certification period — 1 yea
Abnormal Exercise Tolerance Test (ETT) is defined by
-Inability to exceed 6 METS (beyond completion of Stage II, or 6 minutes) on a standard Bruce protocol
or
- presence of ischemic s/s (e.g., characteristic angina pain or 1 mm ST depression or elevation in 2 or more leads)
or
- inappropriate SBP and/or heart rate responses (e.g., inability in the maximal heart rate to meet or exceed
85% of age-predicted maximal heart rate)
or
-ventricular dysrhythmia.
Medium work requires ___________ METs and includes carrying moderate weight objects of up to 50
pounds.
