Verified Answers with Diagrams and

Question 1
A 55-year-old male presents to the ED with chest pain and palpitations. His EKG
shows a regular rhythm with a rate of 120 bpm, upright P waves before each QRS,
normal PR interval (0.16 sec), and normal QRS complexes. Diagram Description:
[Textual Illustration: Regular narrow QRS complexes at 120 bpm with consistent P
waves preceding each QRS, resembling a standard sinus rhythm but faster.] What
is the EKG interpretation? A. Atrial fibrillation B. Sinus tachycardia C. Ventricular
tachycardia D. First-degree AV block
B. Sinus tachycardia
Rationale: Sinus tachycardia is characterized by a regular rhythm originating from
the sinus node, with a rate >100 bpm, visible P waves before each QRS, and
normal intervals. This is common in stress, fever, or hypovolemia; treat underlying
cause and monitor for ischemia.
Question 2
A 68-year-old female with hypertension reports dizziness. EKG: Irregularly
irregular rhythm, rate 110 bpm, no distinct P waves, fibrillatory waves, narrow
QRS. Diagram Description: [Textual Illustration: Chaotic baseline with
undulating fibrillatory "f" waves, irregular RR intervals, no organized P waves.]
What is the interpretation? A. Sinus bradycardia B. Atrial fibrillation C. Junctional
rhythm D. Second-degree AV block
B. Atrial fibrillation
Rationale: Atrial fibrillation shows absent P waves replaced by irregular
fibrillatory waves, leading to irregular ventricular response. Risk of
thromboembolism requires anticoagulation assessment (CHA2DS2-VASc score);
rate control with beta-blockers if unstable.
Question 3
, 2
A 42-year-old post-surgical patient has sudden cardiac arrest. EKG: Chaotic,
irregular waveform with no identifiable QRS complexes, rate unmeasurable.
Diagram Description: [Textual Illustration: Coarse, wavy baseline without
organized deflections, resembling a "bag of worms."] What is the rhythm, and
initial action? A. Asystole; start CPR B. Ventricular fibrillation; defibrillate C.
Atrial flutter; vagal maneuvers D. Sinus rhythm; observe
B. Ventricular fibrillation; defibrillate
Rationale: Ventricular fibrillation is a pulseless rhythm with disorganized
ventricular activity, requiring immediate defibrillation (200J biphasic), CPR, and
epinephrine per ACLS. Untreated, leads to death within minutes.
Question 4
A 30-year-old athlete is asymptomatic during routine check. EKG: Regular
rhythm, rate 45 bpm, upright P waves, normal PR and QRS. Diagram
Description: [Textual Illustration: Slow, regular narrow complexes with P waves,
RR interval prolonged >1 sec.] Interpretation? A. Sinus tachycardia B. Sinus
bradycardia C. Atrial flutter D. Ventricular tachycardia
B. Sinus bradycardia
Rationale: Sinus bradycardia (<60 bpm) with normal P waves and intervals is
physiologic in athletes due to high vagal tone. No treatment needed unless
symptomatic (e.g., dizziness); monitor.
Question 5
A 60-year-old with COPD exacerbation shows EKG: Regular atrial rate 300 bpm,
sawtooth flutter waves, ventricular rate 150 bpm, narrow QRS. Diagram
Description: [Textual Illustration: Baseline with continuous "F" waves (sawtooth)
at 300/min, 2:1 conduction to ventricles.] What is this? A. Atrial fibrillation B.
Atrial flutter C. Supraventricular tachycardia D. Third-degree AV block
B. Atrial flutter
Rationale: Atrial flutter features rapid atrial rates (250-350 bpm) with flutter (F)
waves in a sawtooth pattern, often 2:1 AV conduction. Rate control with
cardioversion or drugs; anticoagulation if >48 hours.
Question 6
A 70-year-old diabetic presents with fatigue. EKG: Rate 75 bpm, regular, P waves
present but PR interval 0.28 sec, normal QRS. Diagram Description: [Textual
