1Myocardial Ischemia correlated with
angina
1-2 mm ST depression
radionuclide evidence of ischemia
dysrhythmia
2anginal threshold - max HR ___ bpm below ischemic HR
10
3Dyspnea associated with poorer prognosis if it ______ ex test
limits
4Hemodynamic instability correlated with
abnormal changes in EKG, BP, HR, SpO2
5Decreased CO correlated with
angina
dizziness
low BP
syncope
weak pulse
altered consciousness
anxiety
tachycardia
6What is considered a good GXT?
8-12 mins
achieve 85% age predicted max HR
7How do we know if max effort was reached?
Vo2 plateau - not common for cardiac pts
Failure of HR to increase as workload increases
RPE >17 or 7 modified
8HRR
Heart rate reserve
HR max - HR rest
9if there was no GXT or 85% not achieved, can use
HR data from 6MWT or HR rest + 20-30 or RPE 12-16
NOT age predicted
