34
Stokes-Adams Syndrome

36
3rd degree block looks like
Compare P-P vs R-R, Regular but at their respect rhythm?
37
Wenkebach looks like
Gradually increased PRI w/ failed QRS after last conducted P-wave; p-p is regular
38
PVC compensatory Pause
Ventricles still in refractory from PVC and still need time to repo before continuing
39
Analyzing EKG method
P before every QRS QRS after every P PRI for AV blocks QRS widths for BBB
40
PR seg represents
End of atrial contraction; just before ventricles contract
41
PRI variable
3rd Degree block
42

A-flutter & torsades
43
Tachyarrythmias 350-450
A-fib or V-fib
44

Entire ventricle contraction/relaxation and includes QRS wave ST seg T-wave
46
PRI increased/progressive
2nd degree type I (Wencke)
47
WAP looks like
3 or more P wave morphologies; <100 BPM; causes irregular atrial/ventricle rhythm
48
Sick Sinus Syndrome (4)
SA node dyfx; unresponsive to atrial foci; no escape contractions; Intermittent brady/tachy
49
Tachy arryth differs from sinus tachy in 2 way
GRADUAL response , NO automaticity focus
50
Reset pacing
After a premature contraction; if the depo reaches dominant foci, it will continue only after one full cycle length from the premature stimulus
51
Av node causes depo to
slow down allowing blood to flow from atria to vents
52
WAP is
Irregular Rhythm; PM activity wanders from SA node into atria; Each diff foci produces diff P wave; and foci shift from SA, Atria, AV
53
Reasons for an EKG
Unexplained syncope/dizziness/palpitations SOB, chest pain, Fatigue Neurological from A-fib/A-flutter
54
A fib is
Rapid atrial foci (CHAOS); No depo fully contracts atria; and onle some atria depos reach AV node to conduct Vents

Fibrillation is
Erratic w/ no rhythm - waves are not distinguishable
73

74
What does the bundle of HIS do?
Accelerates depolorization to ventricles
75
