The 12-Lead Confidence Bundle: 3 Pocket Study Cards

You know that feeling. The monitor prints. Twelve leads stare back at you. Your patient is deteriorating and for a split second, your mind goes blank.

Was it two contiguous leads or three? What threshold applies? Is that pattern significant or a normal variant?

ECG interpretation is one of the most critical skills in pre-hospital care and one of the hardest to recall under pressure. Your textbooks are at home. Your notes are buried in a bag. And second-guessing yourself on scene is a feeling nobody wants.

That is exactly why we built this.

Three precision-designed, pocket-sized reference cards that sit on your lanyard and put structured ECG interpretation at your fingertips from first glance to clinical decision.

Card 1- The 7-Step Plan: A systematic walk-through of ECG interpretation: rate, rhythm, axis, P wave and PR interval, QRS complex and QT interval, ST segment changes, and T-wave morphology. No steps skipped. No shortcuts that leave gaps. Every single time.

Card 2- Key Pattern Recognition Reference Criteria: for identifying significant ECG changes with age and gender-specific thresholds. Posterior and right-sided patterns. Pathological Q waves. Plus the presentations that catch people out, De Winter T-waves, Wellens syndrome, and bundle branch block recognition.

Card 3- Transparent ECG Ruler Overlay: it directly onto a 12-lead printout. Heart rate calculation at a glance. PR and QRS interval measurement. Axis determination. Lead territory mapping. T-wave morphology reference. All on one transparent card you place directly on the trace.

This is not about replacing what you know. It is about making sure you never freeze when it matters.

Clip it to your lanyard. Run the same structured approach every time , whether it is your first 12-lead or your thousandth. Walk into every job knowing that when the monitor prints, you have got a system that works.

That is not just a reference card. That is confidence you can carry.

Designed by practising UK paramedics for student paramedics, newly qualified practitioners, and emergency clinicians.
