Cardiology Flashcards
LVEF
helps determine CO –> helpful in dx HF
ex: LVEF of 65% means that 65% of overall amount of blood found in LV is pumped out w/ each cardiac contraction
Acceptable LVEF
40% in all conditions where clearance is dependent on LVEF
ETT
measure of exercise performance required for clearance evaluated by 2 indicators
–exercise to capacity of > 6 metabolic equivalents (METs) (through Bruce Stage II or equivalent)
–attain HR of >85% of predicted max (unless on BBs)
–rise in SBP >20mmHg w/o angina
–significant ST depression or elevation
CAD initial presentation
angina
chest pressure or pain w/ exertion or at rest
palpitations
presyncope or true syncope
refer to cardiology –> cert will be “incomplete”
acute MI
WP = 2 months
bi-annual ETT thereafter
no LVD
DQ = rest angina or changes in angina patter w/ in last 3 months
angina pectoris
implies that at least 1 coronary artery has hemodynamic narrowing
unstable angina
rest angina
changes in angina pattern
decreased response to meds
WP = 3 months w/out rest angina or changes in patterns
stable angina
max cert = 1 year if
cleared by cardio
tolerating meds well
pass annual PE
pass bi-annual ETT
DQ = unstable angina w/in 3 months of exam
CABG
WP = 3 months (min)
max cert = 1 year –> must have yearly annual ETT starting @ 5 years PO d/t to increased r/o re-occlusion overtime
PCI
max cert = 1 year –> must have yearly bi-annual ETT
WP = none if
–asx
–tolerating meds well
–no injury to vasc. access site
implanted cardiac devices
max cert 1 year
WP = depends on underlying dz
–sinus node dysfx or AV block = 1 month
–hypersensitive carotid sinus w/ syncope = 3 months
supraventricular arrhythmias
SVT & A-fib
not considered high r/f sudden death, but can cause LOC or compromise cerebral fx
a-fib = high r/f embolism/stroke
max cert = 1 year if
–HR controlled
–cleared
–adhering to meds
WP for SVT s/p ablation
1 month if:
asx
adequate anticoag tx
dx of
–AVRT/AVNRT
–WPW
–junctional tach
–atrial tach
ventricular arrhythmias
CAD, right outflow VT, idiopathic left VT
max cert = 1 year if
–asx
–non-sustained VT
–EF > 40&
–cleared
WP = 1 month
ventricular arrhythmias DQ
sustained VT
sx
non-sustained VT w/ EF < 40%
VT w/ concurrent dx of
–hypertrophic cardiomyopathy
–long QT syndrome
–brugada syndrome
CHD
max cert = 1 year for dx of
mild tricuspid anomaly
mild cardiac enlargement
mild RV dysfx
cleared, asx, echo
CHD DQs
sx (dyspnea, palps, emboli)
intra-cardiac lesion (ASD)
cardiac shunt
accessory conduction pathway
HF (systolic dysfx)
NYHA most common classification system
Class 1 HF
no limitations, no sx w/ ordinary activity
max cert = 1 year
Class 2 HF
slight, mild limitation of activity, comfortable at rest or mild activity
Class 3 HF
marked limitation of activity, comfortable @ rest only
Class 4 HF
confined to bed/chair; any physical activity elicits sx; sx @ rest
HF DQs
EF < 40%
sustained VT > 30 seconds
Class 2+
Heart transplant WP s/p transplant
1 year
Max cert s/p heart transplant
1 year if:
–cleared by cardiology AND transplant med
–no sx of rejection
–asx
–tolerating meds well
Myocardial dz DQs
hypertrophic cardiomyopathy
restrictive cardiomyopathy
