7-Step ECG Interpretation & ECG Basics Reference Card – Structured Analysis + Visual Learning Tool

Confidently read and understand ECGs with this dual-sided clinical reference card, created to support paramedics, nurses, student clinicians, and anyone learning ECG interpretation. One side features a step-by-step method for structured analysis, while the other provides a visual breakdown of ECG paper and waveforms, essential for mastering ECG timing and morphology.

Side One: The 7-Step ECG Interpretation Plan
A clear, structured approach to ECG interpretation, designed to guide the clinician through the most important elements of analysis. Under each step is a prompt explaining exactly what to assess.

Heart Rate
– Use large and small squares to estimate the rate quickly and accurately
Rhythm
– Assess for regularity
Axis
– Determine normal, left, right or extreme axis deviation using limb leads
P Wave & PR Interval
– Check for P wave shape, presence, and PR interval length and consistency
QRS Complex & QTc
– Measure width of QRS and estimate corrected QT interval
ST Elevation or Depression
– Look for deviation from the isoelectric line in contiguous leads
T Wave Morphology
– Assess shape, direction, and symmetry for signs of pathology

Note: A normal 7-step review does not guarantee a normal ECG—it simply provides a structured method. Always interpret in clinical context and refer to local guidance.

Side Two: ECG Paper Basics & PQRST Waveform Guide
An enlarged ECG paper diagram with a colour-coded PQRST waveform, providing a visual learning aid for beginners and a refresher for advanced users.

Paper Measurements:
• 1 small square = 40 ms
• 1 large square = 200 ms
• 5 large squares = 1 second

PQRST Labelling:
• P Wave: Atrial depolarisation
• QRS Complex: Ventricular depolarisation
• T Wave: Ventricular repolarisation
• PR Interval (PRI): Time from atrial depolarisation to ventricular depolarisation
• QT Interval: Total time for ventricular depolarisation and repolarisation

Normal Ranges (based on UK guidelines):
• PRI: 120–200 ms
• QRS: <120 ms
• QTc: <440 ms (men), <460 ms (women)

Product Features:

- Size: 86mm x 54mm (credit card size – fits lanyards and ID holders)
- Material: Gloss-finished, PVC plastic, waterproof and wipe-clean
- Design: Clean, educational layout with structured prompts and visuals

Bundle:
