ECG Master Guide

A systematic 9-step approach to rhythm and ischaemia

The ECG Master Guide teaches one disciplined reading sequence and applies it to 120 annotated tracings, from sinus bradycardia to Brugada patterns.

Every rhythm strip is rendered at true 25 mm/s scale with a calibrated grid overlay, so measurements you practise transfer directly to the monitor.

Chapters close with timed self-assessment blocks modelled on OSCE and USMLE-style stations.

Learning outcomes

Apply the 9-step interpretation sequence to any 12-lead ECG in under 90 seconds.
Distinguish atrial fibrillation, flutter and multifocal atrial tachycardia by P-wave morphology.
Localise STEMI territory and identify the culprit vessel from ST elevation patterns.
Recognise hyperkalaemia, digoxin effect and pericarditis on the tracing.
Measure axis, intervals and R-wave progression reliably with calipers.

01
The basics
What the ECG actually records, how the heart's electrical system produces it, and how to read the paper.
Pages 1–9
02
Waves and intervals
Every deflection on the tracing, what produces it, and the numbers that make it normal or abnormal.
Pages 10–17
03
Rate, rhythm and axis
The three measurements that open every report, each with a bedside shortcut and its failure modes.
Pages 18–22
04
The nine-step method
One repeatable sequence applied to every tracing in this book, and the discipline that makes it reliable.
Pages 23–26
05
Rhythms
Sinus variants, the supraventricular tachycardias, atrial fibrillation and flutter, and the ventricular rhythms.
Pages 27–35
06
Conduction blocks
AV blocks from first degree to complete dissociation, plus bundle branch and fascicular blocks.
Pages 36–40
07
Ischaemia and infarction
STEMI criteria, territory mapping, the mimics, and the subtle occlusion patterns that criteria miss.
Pages 41–47
08
Worked ECG cases
Every case solved with the same nine steps, then explained. All examples are educational, not real patient records.
Pages 48–64
09
Quick reference
The tables worth keeping open during a shift, plus a final review checklist.
Pages 65–69
