BAYCARE EKG TEST (SOLVED) 2025/2026 CORRECT!!

BAYCARE EKG TEST (SOLVED) 2025/2026 CORRECT!!

EKG Strip Diagram:

• Rhythm: Irregularly irregular

• Atrial Rate: Unable to determine, baseline is chaotic and wavy

• Ventricular Rate: 140 bpm

• P-waves: Absent, no discernible P-waves

• PR Interval: Not measurable

• QRS Complex: 0.08 sec (narrow)



What rhythm does this strip represent?
A) Atrial Flutter
B) Atrial Fibrillation
C) Ventricular Tachycardia
D) Sinus Tachycardia
E) 2nd Degree Heart Block Type I
Correct Answer: B) Atrial Fibrillation
Rationale: The rhythm is identified as Atrial Fibrillation due to the irregularly irregular
pulse, the heart rate greater than 100 bpm (uncontrolled), and the absent P-waves with a
chaotic baseline.

Question 2



EKG Strip Diagram:

• Rhythm: Regular

• Atrial Rate: ~300 bpm

• Ventricular Rate: 150 bpm

• P-waves: Replaced by a classic "saw-tooth" pattern of flutter waves

, • PR Interval: Not measurable

• QRS Complex: 0.06 sec (narrow)



What rhythm does this strip represent?
A) Atrial Fibrillation
B) Sinus Tachycardia
C) Atrial Flutter
D) Ventricular Fibrillation
E) 1st Degree Heart Block
Correct Answer: C) Atrial Flutter
Rationale: The rhythm is identified as Atrial Flutter due to the rapid atrial rate (240-350
bpm) and the characteristic saw-tooth pattern of the atrial waves.

Question 3



EKG Strip Diagram:

• Rhythm: Underlying rhythm is regular, interrupted by an early beat.

• Rate: Underlying rate is 75 bpm.

• P-waves: Normal sinus P-waves with the underlying rhythm. The early beat has no P-
wave.

• PR Interval: 0.16 sec on the sinus beats.

• QRS Complex: 0.08 sec on the sinus beats. The early beat has a wide, bizarre QRS
measuring 0.14 sec.



This strip shows an underlying sinus rhythm with which ectopic beat?
A) Premature Atrial Complex (PAC)
B) Premature Junctional Complex (PJC)
