ECGS- ARRT CI
1st degree heart block - ANS-impulses from sa node to vent. are delayed, not blocked
2:1 AV block - ANS-2 p waves occur for every QRS
2nd degree heart block - ANS-intermittent disturbance in the impulses between the atria
and ventricles
2nd degree type 1 other names - ANS-Mobitz 1, Wenkebach
3rd degree heart block - ANS-complete block in the conduction of impulses between the
atria and ventricles
a bipolr lead contains a positive & negative electrode @ the - ANS-tip
a delayed conduction w/ 1st degree block means - ANS-a longer PR interval
a secondary ___________ stimulate the _____________ in 3rd degree block -
ANS-pacemaker, ventricles
a unipolar electrode means the neg. electrode is at the ______ and the positive
electrode is the ___________ - ANS-tip, pulse generator
ABERRANTLY CONDUCTED PACS HAVE A _______ QRS - ANS-WIDE
adenosine dose - ANS-Rapid IV push 6mg followed by NS flush; Second dose of 12mg
if required
advanced 2nd degree av block - ANS-3 or more consecutive p waves with no QRS
amiodarone dose - ANS-150 mg IV over 10 min
another name of asystole - ANS-cardiac standstill
are p waves identifiable in afib? - ANS-no
Are their p waves in ventricular escape beats? - ANS-absent or after QRS if retrograde
conduction occurs
, ARE THERE P WAVE IN AVNRT? - ANS-OFTEN HIDDEN IN THE QRS, NEGATIVE P
WAVES MAY BE OCCUR IF VENTRICLES ARE STIMULATED FIRST
atria fire____ time due to afib - ANS-300 to 600 times
atrial fibrillation - ANS-one or several rapidly firing sites in the atria
ATRIAL FLUTTER IS CAUSED BY... - ANS-IRRITABLE SITE WITHIN ATRIA FIRES A
VERY RAPID RATE. REENTRY IMPULSE CIRCLE IN ATRIA
atrial flutter treatment when patient is stable - ANS-beta blockers to control the
ventricular rate
ATRIAL SYSTOLE- CARDIAC CYCLE - ANS-ATRIA CONTRACT- ATRIA PUSH
BLOOD INTO THE VENTRICLES
ATRIAL TACHYCARDIA - ANS-REGULAR RHYTHM WITH A RAPID ATRIAL RATE
ATRIOVENTRICULAR NODAL RE ENTRANT TACHYCARDIA - ANS-MOST COMMON
TYPE OF SVT- 2 PATHWAYS IN THE AV NODE THAT CONDUCT IMPULSES A DIFF.
SPEEDS AND RECOVER AT DIFF. RATES
ATRIOVENTRICULAR NODE - ANS-AFTER SA NODE- DELAYS IMPULSE TO
BUNDLE OF HIS TO ALLOW ATRIA TO CONTRACT
ATRIOVENTRICULAR REENTRANT TACHYCARDIA - ANS-IMPULSE EXCITES THE
VENTRICLES EARLIER THAN EXPECTED- ABNORMAL CONDUCTION
atropine dose - ANS-0.6 to 1.2 mg iv
BUNDLE OF HIS - ANS-AFTER AV NODE- RELAYS IMPULSE TO R AND L BUNDLE
BRANCHES
cardiac output and stroke volume _____________ due to afib - ANS-decrease
DILTIAZEM DOSE - ANS-10 MG iv
DRUG OF CHOICE FOR SYMPTOMATIC BRADYCARDIA - ANS-ATROPINE
