KAISER EKG QUESTIONS AND ANSWERS SET A+
✔✔Long PR interval can mean - ✔✔heart block
✔✔V1 is placed - ✔✔on 4th inrercostal space to right of sternum
✔✔v2 is places - ✔✔on 4th intercostal space to left of sternum
✔✔V3 is placed - ✔✔between v2 and v4
✔✔v4 is placed - ✔✔on the fifth intercostal space in the midclavicular line
✔✔v5 is placed - ✔✔between v4 and v6
✔✔v6 is placed in - ✔✔the fifth intercostal space in midaxillary line
✔✔Sinus arrhythmia is - ✔✔normal rate but speeds and slows with respirations, rhythm
is irregular. p-p varies by more than 10%
✔✔regularly irregular rhythm - ✔✔sinus arrhythmia
✔✔txt for bradycardia - ✔✔is symptomatic, atropine 0.5mg. if unsuccessful, pacemaker
✔✔sinus pause - ✔✔one or two beats arent formed
✔✔sinus arrest - ✔✔3 or more beats are not formed
✔✔sinoatrial exit block - ✔✔SA node gernerates an impulse but its blocked before
being transmitted hence dropped beats. underlying rhythm is maintained
, ✔✔sick sinus syndrome - ✔✔sinus bradycardia (heart rate < 40 bpm), sinus pauses
(sudden pauses of the sinus node shorter than 2-3 seconds), and sinus arrest (sudden
pauses of the sinus node longer than 2-3 seconds).
✔✔sick sinus syndrome txt - ✔✔pacemaker, atropine and epinephrine
✔✔atrial ectopic beat - ✔✔PAC
✔✔PAC txt - ✔✔rarely treated, observe and document frequency and pt condition
✔✔What drug can control/ convert rhythm - ✔✔amiodarone
✔✔Atrial flutter txt - ✔✔beta blockers, diltiazem, verapimil, digoxin
amiodorone to control rhythym
anticoag
IF SYMPTOMATIC, SYNCHRONIZED CARDIOVERSION
✔✔txt for symptomatic atrial flutter - ✔✔synchronized cardioverion
✔✔What to do for unstable tachycardia due to tachyarrhythmia/ afib - ✔✔IMMEDIATE
SYNCHRONIZED CARDIOVERSION
✔✔when should cardioversion be preformed with caution - ✔✔stable afib more than 48
hours old and no anticoagulant therapy has been started
✔✔Paroxysmal SVT - ✔✔>150 bpm, Occurs with no warning lasting a brief period of
time and is self terminating
✔✔txt for stable SVT - ✔✔Vagal maneuvers, adenosine
✔✔txt for unstable SVT - ✔✔Synchronized cardiovert
✔✔what happens to p waves in junctional rhythms - ✔✔flat or inverted
✔✔junctional rhythm rate - ✔✔40-60
✔✔accelerated junctional rhythm rate - ✔✔>60
✔✔1st degree block - ✔✔PR interval >0.20 or 5 boxes
✔✔2nd degree av block type 1 - ✔✔wenckebach- longer and longer pr intervals
followed by a drop
