6 worked ECG Technologist practice questions
Original exam-style questions from the bank, spread across the blueprint domains. They are not real or recalled exam questions. Try each one, then open the answer for the rationale and reference. None of them appear in the free mock exam, so reading them will not spoil it.
Question 1 · Ambulatory Monitoring and Exercise Testing
During a treadmill test, which finding is an absolute indication to stop the test?
- AHeart rate reaching 85% of predicted maximum
- BSustained ventricular tachycardia
- CSystolic blood pressure rising to 180 mmHg
- DFrequent atrial ectopic beats
Show answer and explanation
Correct answer: B. Sustained ventricular tachycardia
Sustained ventricular tachycardia is an absolute indication to stop exercise testing, along with moderate to severe angina, signs of poor perfusion, CNS symptoms and a fall in systolic pressure with other evidence of ischaemia. A rise in systolic pressure to 180 mmHg is a normal response. Reaching a target heart rate is not in itself an absolute stopping criterion.
Reference: Fletcher et al., Exercise standards for testing and training: AHA scientific statement, Circulation 2013
Question 2 · Cardiac Anatomy and Electrophysiology
What electrical event does the T wave on a surface ECG represent?
- AAtrial depolarisation
- BAtrial repolarisation
- CVentricular depolarisation
- DVentricular repolarisation
Show answer and explanation
Correct answer: D. Ventricular repolarisation
The T wave reflects ventricular repolarisation. The P wave is atrial depolarisation and the QRS complex is ventricular depolarisation. Atrial repolarisation is normally hidden within the QRS complex.
Reference: Hampton, The ECG Made Easy, 9th ed.
Question 3 · Conduction Disturbances
Every P wave is followed by a QRS complex, and the PR interval is constant at 260 ms. What is the finding?
- AFirst-degree AV block
- BMobitz type I block
- CMobitz type II block
- DComplete heart block
Show answer and explanation
Correct answer: A. First-degree AV block
A constant PR interval longer than 200 ms with every P wave conducted is first-degree AV block. Second-degree block involves some P waves not being conducted. In complete heart block, P waves and QRS complexes are independent.
Reference: Hampton, The ECG Made Easy, 9th ed.
Question 4 · Arrhythmias
A 30-year-old woman has sudden palpitations. The ECG shows a regular narrow complex tachycardia at 180 per minute with no visible P waves, but a small terminal r wave in V1 that is absent in sinus rhythm. What is the most likely rhythm?
- ASinus tachycardia
- BAtrial fibrillation
- CVentricular tachycardia
- DAV nodal re-entrant tachycardia
Show answer and explanation
Correct answer: D. AV nodal re-entrant tachycardia
In typical AVNRT, the atria and ventricles are activated almost together, so retrograde P waves are hidden in or just after the QRS, sometimes seen as a pseudo r' wave in V1. The rhythm is regular and narrow. Sinus tachycardia has visible P waves before each QRS, and atrial fibrillation is irregular.
Reference: Hampton, The ECG in Practice, 6th ed.
Question 5 · ECG Acquisition, Lead Placement and Artefacts
A posterior ECG is requested. At the same horizontal level as V6, where should V8 be placed?
- ALeft posterior axillary line
- BLeft paraspinal border
- CRight midscapular line
- DLeft midscapular line
Show answer and explanation
Correct answer: D. Left midscapular line
Posterior leads lie at the level of V6: V7 in the left posterior axillary line, V8 in the left midscapular line at the tip of the scapula, and V9 at the left paraspinal border. They help detect posterior infarction. The leads must be labelled clearly on the tracing.
Reference: Society for Cardiological Science and Technology, Clinical Guidelines by Consensus: Recording a Standard 12-Lead ECG, 2020
Question 6 · Ischaemia, Infarction and Other Waveform Changes
Each of the following ECGs is from a patient with chest pain and no left ventricular hypertrophy or bundle branch block. Which one meets ST elevation criteria for myocardial infarction?
- A1.5 mm ST elevation in V2 and V3 in a 55-year-old woman
- B1 mm ST elevation in V2 and V3 in a 50-year-old man
- C0.5 mm ST elevation in leads II, III and aVF
- D1 mm ST elevation in lead III only
Show answer and explanation
Correct answer: A. 1.5 mm ST elevation in V2 and V3 in a 55-year-old woman
New ST elevation at the J point in two contiguous leads is significant at 1 mm or more in most leads, but in V2 and V3 the thresholds are 1.5 mm in women, 2 mm in men aged 40 or over and 2.5 mm in men under 40. A single lead does not meet the contiguous lead criterion. Any concerning ECG should still be shown to a clinician at once.
