ekg kaiser test Questions with Detailed Verified
Answers
if we have too long of ventricular repolarization this may lead to Ans: Vtach and Vfib
ventricular repolarization is represented by Ans: T wave
ventricular depolarization is represented by Ans: qrs complex
to measure the QT interval you measure what Ans: the initiation of the QRS to the
end of T wave
where do you look on the ekg to see if there are abnormalities in ventricular
repolarization Ans: QT interval
QT interval that is too long represents Ans: delay in ventricular repolarization
if there is a a wide QRS complex what can we say about the bundles Ans: there is a
delay in one of the bundles
the ekg shape that looks like bunny ears Ans: right bundle branch block
electrolyte abnormalities that may cause a long QT Ans: hypokalemia
hypocalcemia
hypomagnesemia
When we must shock a pt for afib or tachy what is our emergency intervention Ans:
synchronized cardioversion on the R wave
no SAD node firing for a big pause, then begins to fire again resulting in no P wave
during this event but the PR interval remains normal Ans: sinus pause or sinus arrest
long term tx for pt with afib or aflutter Ans: blood thinners
, this med may possibly cause a 1st degree heart block Ans: dilitiazem
medication that will help get a pt out of Afib Ans: amiodarone
4 SVT interventions Ans: O2, vagal maneuvers, Adenosine, synchronized
cardioversion
3 interetions for idioventricular rhythms Ans: pacers, vasopressor meds like dopamine
and beta agonist,
a pt who has idioventricular rhythm but is pulseess needs what intervention Ans: CPR
and code Blue
hallmark is progressively prolonged PR intervals in this rhythm Ans: second degree AV
blocks Type 1
this rhythm has a delay in impulse conduction resulting in prolonged PR interval the PR
interval is fixed but delayed Ans: first degree AV block
hall mark sign is PR intervals are fixed, with a QRS that is very wide Ans: second
degree AV blocks type II Mobitz type 2
qrs shape of a second degree av block type 1 Ans: qrs narrow
we can surmise that there is a block happening below the AV node by looking at a
QRS inteval in this shape Ans: wide
digitalis toxicity may cause this type of heart block Ans: block third degree
medication intervention for vtach Ans: amiodarone
symptoms are rarely weakness and rarely dizziness Ans: PVC
number one cause of PEA Ans: hypovolemia
