EXAM 2 Flashcards
(59 cards)
PR interval needs to be no more than
5 small boxes, 0.2 msec
QRS complex should be no more than
2.5 small boxes or 0.1 msec
What can causes Sinus Bradycardia and can you work with this patient?
Beta Blocker, and you can work with them as long as they are not symptomatic
A patient that has a sinus arrhythmia, can you work with them?
This would be considered a benign arrhythmia, because conduction is normal. This arrhythmia typically happens at rest, with exercise patient should become normal due to the changes with breathing and intra-throacic pressure. COMMON in AEROBIC athletes.
What type of Arrhythmia is a sinus pause or drop beat?
If a patient had a lot of drop beats, more than 6 in a minute the would become light-headed and symptomatic. This arrhythmia can only bet detected through a HOLTER MONITOR, can be due to a congenital abnormality. Treat with Pacemakers.
What type of arrhythmia is a premature atrial contraction, can you work with this patient?
p-wave more rounded, R-R is regular, one isolated beat, which came early. P wave and q wave look like all the others. considered benign because there is a p wave, normal conduction.
Describe paroxymal atrial tachycardia and can you work with this patient?
normal conduction–>to supraventricular tach, usually seen with mitral valve dysfunction, if HR over 100 probably can’t work with this patient.
Describe atrial flutter and can you work with this patient?
avaiant p waves, look at the rate, if its less than a 100 you can work with the patient, just takes conduction a little longer to get to the AV node because atria are ‘fluterring”
Define Pre-mature nodal contraction and can you work with this patient?
This is a benign arrythmia, no p-wave but has nomral qrs, you can work with them because AV node is still working
Would you work with a patient that displayed “Bradycardia”?
this person is probably symtomatic, so you wouldn’t work with them, you would treat with pace maker.
Describe Junctional/Supraventricular tachycardia.
normal, QRS, no p-wave and very fast rate.
R on T PVC are considered, couplets?
life threatening, couplets are very dangerous.
V-Fib is considered…
a medical emergency,get AED, call code.
Describe first degree AV block and can we work with this patient?
longer than normal time to get to the av node so PR interval is longer but usually a begin block.
Type 1 second degree block is common in what type of a patient?
RCA blockage, infract or ischemia, treated with temp pacemaker, probably wouldn’t be seeing this patient, because they would most likely be in the ER
Type II Second degree block, where a beat drops twice, work with is patient?
nope, pacemaker
What is the signature of a bundle branch block?
notched QRS
What should you monitor changes (HISBED), what are the symtpoms that a patient maybe be having an arrhythmia?
palpitations, dizziness, SOB, racing heart... HYPOXIA ISCHEMIA Bradycardia Electrolyte disturbance (postassium) Drugs (digoxin)
just have one PVC in a 6 sec strip you probably could exercise as long as the rate is alright.
What is the normal range for cardiac index and how is it calculated?
2.6-4.2, a low cardiac index = poor contractility of the left ventricle, cardiac output/body surface area.
If a patient has an LVAD, what vitals will you not be able to measure appropiately?
BP, pulse ox, HR. need to use RPE, and MAP.
What are the factors for heart transplant candidacy?
- less than 1 year to live
- VO2max<14mg/o2…
- no other organ damage
- appropriate BMI
- no smoking/drinking
- Family support.
- no cancer.
A patient who has a heart transplant, their vitals may change how?
elevated resting HR and may take up to 5 minutes to see a rise in HR with exercise.
T/F you can rehab someone with an LVAD as early as 2 weeks post op?
t (watch for decreased o2 sta, OH, ataxia, big changes SBP)
PREDISONE(cortiocosteriod) side effects?
osteoporosis, proximal muscle weakness…
