ECG Test Online: Basic Interpretation Quiz
Short, free ECG quiz for beginners. Instant results and feedback.
This quiz helps you practice basic ECG interpretation by reading rhythm strips and naming common waves and intervals. For more focused rhythm work, try the ecg arrhythmia quiz, or build broader knowledge with cardiology quiz questions and answers. Preparing for emergencies? Check your skills with an acls practice test.

- Identify Normal Versus Abnormal Rhythms -
Distinguish between regular, tachycardic, and bradycardic patterns to pinpoint common rhythm deviations in this basic ECG quiz.
- Analyze Key Intervals and Segments -
Measure PR intervals, QT intervals, and ST segments accurately and assess their clinical significance in ECG interpretation.
- Apply Lead Placement Principles -
Understand how correct electrode positioning affects waveform appearance and troubleshoot common placement errors during ECG practice tests.
- Evaluate Your Interpretation Skills -
Use scenario-based questions in this ECG interpretation quiz to gauge your proficiency and reinforce learn ECG basics effectively.
Cheat Sheet
- Identify PQRST Waveforms -
The PQRST complex forms the foundational basis for any basic ECG quiz and ecg practice test, representing atrial depolarization (P wave), ventricular depolarization (QRS complex), and ventricular repolarization (T wave). Use the mnemonic "Perky Queens Quickly Triumph" to sequence the phases, making it easier to learn ecg basics. Accurate wave recognition boosts confidence when you tackle an ecg interpretation quiz.
- Calculate Heart Rate Efficiently -
A quick method from the American Heart Association suggests counting large boxes between R-R intervals: Heart rate = 300 ÷ number of large squares, ideal for any ecg quiz online. This formula sharpens your skill set during a basic ECG quiz and ecg practice test. Regular rate calculation practice helps you recognize tachycardia and bradycardia patterns instantly.
- Measure Key Intervals Precisely -
According to ACC/AHA guidelines, normal PR intervals range from 120 - 200 ms, QRS duration is under 120 ms, and QTc uses Bazett's formula (QTc=QT/√RR) to adjust for rate. Mastering these benchmarks is central to acing an ecg interpretation quiz and essential when you learn ecg basics. Precise interval measurements help detect conduction delays and repolarization issues.
- Recognize Core Arrhythmias -
Spot atrial fibrillation's "irregularly irregular" rhythm or PVCs' premature broad QRS complexes by referencing peer-reviewed cardiology resources. The "TAP" mnemonic (Tachyarrhythmia, Atrial, Premature) streamlines recall during an ecg quiz online or ecg practice test. Frequent exposure to rhythm strips builds pattern recognition muscle memory.
- Use a Systematic Interpretation Checklist -
Apply the RRAIM approach - Rhythm, Rate, Axis, Intervals, Morphology - recommended by leading medical schools to ensure no element is overlooked. This stepwise framework enhances performance on a basic ECG quiz or any ecg interpretation quiz. Consistent use of RRAIM cements a reliable method as you learn ecg basics and integrate them into clinical care.
