TOPIC 1: BASIC RHYTHM INTERPRETATIONS
12 Questions • 11.2% of Exam • This topic focuses on identifying and understanding various normal and abnormal heart rhythms.
QUESTION 1

Figure Q1: Reference Image
Answer: Atrial Flutter
Rationale: Sawtooth waveforms on the electrocardiogram, representing rapid, regular atrial depolarization at a rate of
250-350 beats per minute, characterize atrial flutter. This pattern arises from a reentrant circuit within the atria, typically
around the tricuspid annulus.

Figure Q2: Reference Image
Answer: Normal Sinus Rhythm

, STUDENT STUDY & MASTERY EDITION PRACTICE & REVIEW GUIDE
Rationale: A normal sinus rhythm is characterized by regular R-R intervals, a heart rate between 60-100 beats per minute,
upright P waves in lead II preceding each QRS complex, and a consistent PR interval, reflecting normal electrical
conduction originating from the sinoatrial node. This pattern signifies the heart's intrinsic pacemaker functioning
appropriately to maintain cardiac output.
QUESTION 3
[Image].
Figure Q3: Reference Image
Answer: Sinus Tach
Rationale: Sinus tachycardia is characterized by a heart rate exceeding 100 beats per minute with normal P waves
preceding each QRS complex, indicating that the impulse originates from the sinoatrial
node. This rhythm requires identifying the underlying cause, such as fever, hypoxia, or stress, for appropriate management.
