ECG Interpretation Card – 7-Step Method

Read any ECG with confidence — one step at a time.

A two-sided pocket card that breaks ECG interpretation into a clear, repeatable 7-step method, from rate and rhythm through to ST segments and T waves. Built for clinicians learning to read ECGs systematically rather than guessing.

What's on the card

Front — the full 7-step interpretation method:

• Heart rate, with normal ranges (60–100 bpm) and tachycardia/bradycardia thresholds
• Rhythm analysis — regular, irregular, regularly and irregularly irregular
• Axis — normal, left, right and extreme
• P waves and PR interval (normal 120–200 ms), including P–QRS relationship and morphology
• QRS complex and QT interval, with normal durations and QTc ranges
• ST segment — isoelectric baseline, elevation, depression and ischaemia
• T waves — normal shape, inversion and increased amplitude

Reverse — common ECG abnormalities and their diagnostic clues:

• Bradycardia, prolonged and short PR, narrow and broad QRS, prolonged QTc
• Associations including heart block, bundle branch blocks, electrolyte imbalance, drug effects, pre-excitation (WPW, LGL) and myocardial infarction
• T wave patterns — peaked, inverted, biphasic, hyperacute, flattened and camel-hump — with likely causes

Details

• Size: 86 × 54 mm (credit-card sized)
• Two-sided, fully laminated for durability
• Elongated slot for lanyards, badge reels or ID holders

Who it's for

Student paramedics, paramedics and nurses learning structured ECG interpretation — ideal for placement, revision and OSCE prep.
