RHYTHM ANALYSIS TECHNICIAN 2026 STUDY
GUIDE COMPLETE ECG INTERPRETATION
CARDIAC RHYTHM RECOGNITION AND
PRACTICE QUESTIONS
◉ Adequate electrode gel purpose. Answer: To prevent wandering
baseline, ensure proper adhesion of electrodes, facilitate electrical
conductivity, and reduce patient discomfort.
◉ Stable blood pressure indication. Answer: Normal heart activity.
◉ Essential tools for remote cardiac device monitoring. Answer:
Batteries, electrodes, rubber band, adhesive tape.
◉ First-degree AV block indication. Answer: Prolonged PR interval.
◉ Heart rhythm with prolonged PR interval until QRS dropped.
Answer: Second-degree AV block, Mobitz type I.
◉ Most common output for a 12-lead ECG. Answer: Printed format.
◉ P wave analysis feature. Answer: Size and shape.
,◉ Atrial rate from peak to peak flutter waves. Answer: 120 bpm.
◉ Causes of ectopic beats in ECG. Answer: Dehydration, excessive
artifact, electrolyte imbalances, age-related decline.
◉ Action during routine pacemaker check with shortness of breath.
Answer: Put the patient on hold and call the pacemaker nurse.
◉ Valves preventing backflow during diastole. Answer: Semilunar.
◉ Information not used for patient identification. Answer: Room
number.
◉ Isoelectric line of ECG tracing indication. Answer: No electrical
activity.
◉ Correct practice in patient care documentation. Answer: The ECG
was performed; however, the patient was belligerent.
◉ Chain of infection proper sequence. Answer: Source, means of
transmission, susceptible host.
,◉ Sinus arrest. Answer: Considered when it continues for 5 seconds
or more.
◉ First degree heart block. Answer: PR interval is constant and
greater than 0.20 seconds in duration.
◉ ECG interpretations. Answer: Usually the responsibility of a
physician.
◉ Telemetry monitor operator. Answer: Typically operated by a
nurse.
◉ Ventricular dysrhythmia depolarization. Answer: Takes longer
than normal because the current is initiated within the Purkinje
fibers, and the electrical stimulation occurs from the ventricular cell-
to-cell conduction.
◉ Second degree AV block type I. Answer: Another name is
Wenckebach.
◉ Ventricular fibrillation. Answer: Typically described as chaotic.
◉ Patient safety process. Answer: Critical for ensuring patient safety
in a clinical setting.
, ◉ Structure transporting blood to lungs. Answer: Pulmonary artery.
◉ Legality and ethics relationship. Answer: Illegal acts are not
always unethical.
◉ Rhythm characterized by regularity and five complete cycles.
Answer: Sinus rhythm.
◉ Dysrhythmia with irregularity and no distinguishable P waves.
Answer: Atrial fibrillation.
◉ Stimulation of electrical current from pacemaker generator.
Answer: Triggered.
◉ Dual chamber pacemaker's ventricular lead sensing non-cardiac
signal. Answer: Most likely to result in failure to capture ventricle.
◉ Assessing regularity of an ECG. Answer: Involves measuring
distances between R-R intervals.
◉ ECG characteristic indicative of myocardial ischemia. Answer:
Changes in the ST segment and T waves.
