Cardiac dysrhythmias part 2 Questions with
100% Complete Solutions, Rated A+
Prolonged AV conduction. ECG PR interval > 0.20
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION A
Caused from ischemia, drug toxicity, hypokalemia and is asymptomatic. Treatment
consists of dig level, K+ level, monitor for lengthening- further block
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION A
Progression of time It takes for impulse to get from SA to AV node until one
doesn't get through at all
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION A
, ECG shows gradual lengthen of the PR interval- and nonconductor atrial impulse
(blocked ventricular beat- QRS)
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION B
Caused from drugs, ischemia/infarct, is usually transient and asymptomatic-
monitor for further heart block and symptomatic bradycardia
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION B
Treatment is atropine (symptomatic) or temporary pacer (post MI)
A. First Degree AV Block
B. Second-Degree AV Block Type I (Mobitz I or Wenchebach)
C. Second-Degree AV Block Type II
D. Third Degree AB Block (Complete heart block) - cORRECT sOLUTION B
SA fires regularly, only some impulses are sent through. ECG shows regular R-R,
constant JPR interval, and noncunducted P waves & measured by ratio of success-
2:1, 3:1, or variable
