BAYLOR SCOTT & WHITE EKG TEST 4 FULL
PRACTICE QUESTIONS WITH ECG STRIP
ANALYSIS AND ARRHYTHMIA RECOGNITION


◉ Sinus Bradycardia.
Answer: •Rate: <60bpm


•Rhythm: regular


•P:QRS: 1:1


•PR interval: 0.12-0.20 sec


•QRS complex: 0.6-0.10 sec


*Management:
-treated only if symptomatic. IV atropine or isoproterenol, and/or
pacemaker therapy may be used


◉ Sinus Bradycardia Rhythm.
Answer:

,◉ Atrial Flutter.
Answer: •Rate: atrial 240-360 bpm; ventricular rate depends on
degree of AV block and usually is < 150 bpm


•Rhythm: atrial regular; ventricular usually regular


•P:QRS: 2:1, 4:1, 6:1; may vary


•PR interval: not measured


•QRS complex: 0.6-0.10 sec


*Management:
-synchronized cardioversion; medications to slow ventricular
response such as a beta-blocker or calcium channel blocker, followed
by a Class 1 antidysrhythmic agent or AMIODARONE


◉ Atrial Flutter Rhythm.
Answer:


◉ Atrial Fibrillation (A-fib).

, Answer: •Rate: atrial 300-600 bpm (too rapid to count); ventricular
100-180 bpm in untreated patients


•Rhythm: irregularly irregular


•P:QRS:
variable


•PR interval: not measured


•QRS complex: 0.06-0.10 sec


*Management:
-synchronized cardioversion; medications to reduce ventricular
response rate: metoprolol, diltiazem, or digoxin; anticoagulant
therapy to reduce risk of clot formation and stroke


◉ Atrial Fibrillation (A-fib) Rhythm.
Answer:


◉ Premature Ventricular Contractions (PVCs).
Answer: •Rate: variable
