ECG Analysis: Rhythm Recognition - Relias Test Domains


Basic ECG Fundamentals & Measurements
• ECG paper: small square 0.04 sec, large square 0.2 sec, 5 small = 1 large
• Rate: 300-150-100-75-60-50 method, 6-sec x10
• Intervals: PR 0.12-0.20, QRS <0.12, QT
• P wave, QRS complex, T wave identification


Sinus Rhythms & Atrial Rhythms
• Normal sinus, sinus bradycardia <60, tachycardia >100, arrhythmia
• Atrial: PAC, atrial flutter sawtooth 250-350, atrial fibrillation irregularly irregular no P
• Atrial flutter vs fib differentiation
• Wandering atrial pacemaker


Junctional & Ventricular Rhythms
• Junctional: PJC, junctional rhythm 40-60, accelerated 60-100, tachycardia >100
• Ventricular: PVC, V-tach monomorphic/polymorphic, V-fib, asystole, idioventricular
• PVC types: unifocal, multifocal, bigeminy, trigeminy, R-on-T
• Torsades de pointes - polymorphic VT with prolonged QT


Heart Blocks & AV Conduction
• 1st degree AV block: PR >0.20 all P conduct
• 2nd degree Type I Wenckebach: progressive PR lengthening then dropped QRS
• 2nd degree Type II: fixed PR with intermittent dropped QRS - dangerous
• 3rd degree AV block: complete dissociation, atrial rate > ventricular


Life-Threatening & Treatment Priorities
• Lethal rhythms: V-fib, pulseless V-tach, asystole, PEA
• Treatment: defibrillation for V-fib/V-tach, pacing for bradycardia/blocks
• Drugs: atropine, amiodarone, lidocaine, epinephrine per ACLS
• Artifact vs true rhythm recognition


Relias Exam Strategies & 12-Lead Clues
• Systematic approach: rate, regularity, P waves, PR interval, QRS
• Relias tricky: PAC vs PJC vs PVC differentiation
• ST elevation/depression clues in 12-lead
• Bundle branch blocks: wide QRS, RSR' in V1/V6

, QUESTION 1: Relias: Rhythm with sawtooth flutter waves, atrial rate 300, ventricular
rate 150, regular?
A) Atrial flutter with 2:1 conduction
B) Atrial fibrillation
C) Sinus tachycardia
D) V-tach

CORRECT ANSWER: A) Atrial flutter with 2:1 conduction
RATIONALE: Atrial flutter: sawtooth flutter waves, atrial rate 250-350, regular. 2:1 conduction gives
ventricular rate ~150. Atrial fibrillation irregularly irregular, no distinct P/flutters.


QUESTION 2: Irregularly irregular rhythm, no P waves, no distinct pattern?
A) Atrial fibrillation
B) Atrial flutter
C) Normal sinus rhythm
D) Sinus bradycardia

CORRECT ANSWER: A) Atrial fibrillation
RATIONALE: A-fib hallmark: irregularly irregular R-R, no P waves, fibrillatory baseline. Risk stroke, needs
anticoagulation assessment. Rate controlled vs uncontrolled.


QUESTION 3: Wide QRS >0.12 sec, no P waves, rate 160, regular?
A) Ventricular tachycardia
B) Sinus tachycardia
C) Atrial flutter
D) Normal sinus

CORRECT ANSWER: A) Ventricular tachycardia
RATIONALE: V-tach: wide QRS >0.12 sec, rate >100 (typically 150-250), regular, no P waves or AV
dissociation. Medical emergency - pulseless V-tach needs defibrillation per ACLS.


QUESTION 4: No QRS, chaotic wavy baseline, no pulse?
A) Ventricular fibrillation
B) Atrial fibrillation
C) Asystole
D) Normal sinus

CORRECT ANSWER: A) Ventricular fibrillation
RATIONALE: V-fib: chaotic irregular wavy baseline, no QRS, no pulse, fatal - needs immediate defibrillation
and CPR. Coarse vs fine V-fib.


QUESTION 5: Progressive PR prolongation then dropped QRS, PR gets longer until
QRS drops?
A) 2nd degree AV block Type I Wenckebach
B) 2nd degree Type II
C) 1st degree AV block
D) 3rd degree block
