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: • QTc:
