Exercise Tolerance Testing Flashcards
1
Q
Who first recorded the connection between ST depression and angina, and on what year?
A
Feil and Siegel reocrded the first instance in 1928.
2
Q
How did Bruce contribute to the development of stress testing?
A
Bruce invented calibrated protocols and aerobic principles.
3
Q
What are 12 signs that a person could use an ETT?
A
- post-MI
- post-CABG
- post-cardiac surgery
- tease out arrhythmias
- create exercise prescription
- chronic lung disease
- CKD
- PVD
- post-angioplasty
- post-valve replacement
- evaluation of high-risk person
- evaluate suspected heart disease
4
Q
Under which condition should an exercise test be halted, without question (8 answers)?
A
- drop in SBP >10mmHg from baseline + other sx ischemia
- moderate-severe angina
- nervous system abnormalities (clumsiness, dizziness, near syncope)
- signs of poor perfusion (cyanosis, pallor)
- technical difficulties in monitoring ECG or BP
- pt wants to stop
- sustained vTach
- ST elevation without q-waves (except in V1 or aVR)
5
Q
When testing for CAD, what class do people with baseline WPW, pacemaker rhythms, >1mm ST depression, or LBBB fall under?
A
Class III
6
Q
Which 9 findings indicate severe ischemic heart disease?
A
- ST depression developing before 3min exercise time
- ST depression >2.5mm
- downsloping ST depression
- ST elevation
- ST depression >8min into recovery phase
- serious arrhythmias developing at <130 bpm heart rate
- chronotropic incompetence
- > 10 mmHg drop in SBP during exercise
- inability to exercise longer than 3min
