CV Surgical (ICU Test 2)Betty Neuman Health care system model - ANS-What is the nursing theory based on
the individual's relationship to stress, the reaction to the stressors, and the reconstitution
factors that are dynamic in nature?
Pulse Generator - ANS-_________ generates the electrical current that travels directly
to the heart and initiates myocardial depolarization
Pacing Lead - ANS-___________ is the 1,2, or 3 electrodes that may be unipolar (one
neg) or bipolar (one neg one pos)
Dysthymias that are unresponsive to meds
Bradydys
Tachydys
Support of CO after cardiac therapy - ANS-what are some indications for pacing?
sinus bradycardia, 2nd and 3rd heart block - ANS-What are the bradydysrhythmias?
increase ventricular rate thereby enhancing CO - ANS-What is the goal of
bradysrhythmias pacemaker therapy?
use overdrive pacing to decrease the rate prevents/interrupts breakthrough ectopy
(results from a slow rate) allows the natural pacemaker to regain control - ANS-what is
the goal of tachydsrhythmias pacemaker therapy?
transcutaneous pacemaker
symptomatic bradycardia - ANS-What is Typically used as short-term therapy - 1st line
(emergency), quickest way to achieve rhythm and adequate CO?
ACLS recommends this for treatment of _____________ that doesn't respond to
atropine
Transvenous pacing - ANS-_______ pacing electrode wire through a central line is
advanced through the internal jugular vein to the RA, RV, or both (connected to a pacer
box)
transthroacic (epicardial) - ANS-_____ pacing--electrodes are sewn to the epicardium
during cardiac surgery to maintain the CO postop
, right ventricular pacing - ANS-A leadless pacemaker is reserved for _________ only
VF/VT, prevention of sudden cardiac death in HF patients, lethal arrhythmias could be
induced during EPS, ischemic heart disease - ANS-What is an implantable defibrillator
used for:
Decrease HR
A-fib
V-tach/V-fib - ANS-Pacing?
Cardioversion?
Debrillation?
40%
PACE, CARDIOVERT AND DEFIBRILLATE - ANS-PPM's can increase CO by ______
AICD (auto implantable cardiovert defibrillator) does what?
R - ANS-Cardiovert shocks on top of ________ waves
the cardiac chamber that is paced - ANS-What does the first letter of the pacemaker
stand for?
the cardiac chamber that is sensed - ANS-What does the second letter of the
pacemaker stand for?
mode (pacemakers response to the sensed event)
triggered or inhibited - ANS-What does the third letter of the pacemaker stand for?
Synchronous - ANS-______ delivers temporary pacing stimulus only when the heart's
intrinsic pacemaker fails to function at predetermined rate; stimulus is either inhibited or
triggered by the sensing of intrinsic activity
Asynchronous - ANS-_____ delivers temporary pacing stimulus at a set (fixed) rater
regardless of the occurrence of spontaneous myocardial depolarization-- occurs in
non-sensing modes
Rate control - ANS-_____ regulates the number of impulses delivered to the heart per
minute
