EKG INTERPRETATION HCA COMPREHENSIVE
TEST 2026 COMPLETE QUESTIONS AND
ANSWERS
◉ 5.) Determine QRS Complex. Answer: Normal 0.04-0.10 seconds
◉ 6.) Identify Rhythm. Answer: Learn the characteristics of rhythms
◉ 7.) Determine significance of rhythm and treatment. Answer:
◉ Look at examples. Answer:
◉ 3 Major Categories of Rhythm. Answer: 1.) Sinus Rhythms
2.) Ventricular Dysrhythmias
3.) Atrial Dysrhythmias
◉ Sinus Rhythms. Answer: Normal sinus rhythm (NSR): normal
Sinus bradycardia
,Sinus tachycardia
◉ Ventricular Dysrhythmias. Answer: Premature ventricular
contractions (PVCs): with an underlying rhythm
Ventricular tachycardia: can be lethal (V tach, VT)
Ventricular fibrillation: lethal (V fib, VF)
Ventricular asystole/Asystole: lethal (asystole)
More concerning than atrial dysrhythmias!
◉ Atrial Dysrhythmias. Answer: Premature atrial contraction(PACs)
Atrial fibrillation (Afib)
Atrial flutter
◉ Nice to know rhythms. Answer: Atrioventricular (AV) blocks
-First degree
, -Second degree: type I and type II
-Third degree/Complete heart block
Junctional rhythms
◉ Normal Sinus Rhythm. Answer: Rate: 60-100/minute
Regularity: regular
P waves: present, look the same, before every QRS
PR interval: 0.12-0.20 seconds and constant
QRS duration: 0.04-0.10 seconds and constant
Practice with:
Rate ____
Regularity _________
P waves _______
PR interval _______
QRS ______
