|
A dysrhythmia has to contain at least one of the following abnormalities: (SAC acronym) |
1. Synctium 2. Automaticity 3. Conductivity |
|
|
SYNCTIUM |
free flow of electrical impulse through cardiac cells |
|
|
AUTOMATICITY |
the hearts own electrical capabilities (movement of Na+, K+, and Ca++) |
|
|
CONDUCTIVITY |
special pathways to carry impulse |
|
|
How do you treat a 2nd degree AV block (type 1) if it is symtomatic? |
treat like bradycardia but usually asymptomatic |
|
|
A 1st degree AV block is normal except for what? |
PR interval greater than .2 |
|
|
Epinephrine |
Increases HR and contractility -give with symptomatic brady -slam it IV with pulseless v-tach |
|
|
Vasopressin |
pressor and antidiuretic properties (anti-pee pee)...prevents loss of water from the body -treat v-tach without a pulse |
|
|
atropine |
blocks vagal responses to the heart; increases HR -treat with brady |
|
|
Digoxin |
increases contractility, decreases heart rate |
|
|
Beta Blockers (-olol) |
decreases contractility and HR -give with sinus tachy, and PSVT |
|
|
calcium channel blockers (end in -pine) |
decrease HR, block calcium influx -give with sinus tachy |
|
|
adenosine |
-antiarrhytmic agent, slows conduction trough SA and AV node -give IV for PSVT |
|
|
ibutilide |
prolongs the action potential -give bolus with A-fib |
|
|
what is an agonal rhythm? |
body not perfusing. nonfuntional, body using up all chemical or electrical energy; escaped beats |
|
|
amiodarone |
acts directly on cardiac tissue, prolongs duration of action potential and refractory period -tx: ventricular arhythmias or atrial w/ rapid ventricular response |
|
|
where do you place paddles for defibrilation? |
1. to the right of the sternal border 2. lower portion of the rib-cage; mid-axilariary on the left side |
|
|
what are the 3 components to a pacemaker? |
1. pulse generator 2. battery 3. leads |
|
|
what do we do for a pt. who receives a subcutaneous temporary pacemaker? |
1. painful, so we usually sedate 2. afterwards there will be a burn so we dress with silvadine after removing |
|
|
what is our highest concern for a patient with a transvenous temporary pacemaker (inserted with a swan ganz)? |
****DISLODGEMENT!!!! -NO LIFTING >10lbs for 2 months (can dislodge) -infection is a risk but not the highest concern |
|
|
what do you teach someone who just had a permanent pacer put in? |
-passive range of motion on affected arm for 48 hours...don't raise arm right away (first 2-3 days) -wound care (usually staples) -no lifting >10lbs for 2 months -avoid magnets, welding, MRIs, constricting clothing -card with type of pacer and settings at all times -**Notify MD if HR>5 below min. rate -may set of metal detectors (story about old couple in the airport) |
|
|
What is the most important nursing diagnosis with for a person with a pacer? |
RISK FOR DECREASED CARDIAC OUTPUT -if lead comes off, going to kill them a lot faster than an infection |
