Look inside
Read an unknown tracing, check your interpretation, then compare four recordings from a rewarming sequence. Select a page to enlarge.
Read case 14 in text
A 64-year-old with palpitations has a regular narrow-complex rhythm at about 150 beats/min. Which atrial activity would you look for before naming the rhythm?
Reveal the worked answer
In this simulated case the inferior leads show flutter waves, with two atrial waves for each QRS. One wave is partly hidden in the preceding T wave. The annotated sample shows how the atrial and ventricular rates relate.
Inside the workbook
Read a tracing before you see its interpretation. Record what you notice, reveal the annotated answer, then compare how the ECG changes over time.
For junior doctors, emergency nurses, paramedics and advanced clinical students practising ECG interpretation and handover.
Build a systematic read
Nine foundation chapters cover calibration, rate, rhythm, axis, intervals, morphology, territories, artefact and a 12-step read.
Work through 50 presentations
42 cases use a 12-lead layout and eight use a rhythm strip. Each case gives you seven fields to record your read before you open the interpretation.
Compare what changes
Six serial sequences follow a finding over time. Six lookalike comparisons explore features that help distinguish similar patterns.
Revisit a finding
A finding guide, bookmarks, subject index and printable pocket cards support short, focused revision sessions.
Before you buy
How do I receive and use my PDF?
After checkout, use your Gumroad download link and save the file to read it offline. A PDF reader with form support lets you type and save your answers. You can also print the exercises for personal study.
How was the material created?
The patient histories are fictional. Dr Osolika created the ECGs as model-generated teaching illustrations. The clean and annotated views of a case share the same waveform, so you can see where your interpretation changed. Read about the author’s clinical governance and corrections process.
Does the book include the app or CPD credit?
The purchase covers the English-language PDF. The app and its optional Pro subscription are separate. The book is educational and carries no accredited CPD credits. Use local protocols in clinical practice.
Where can I get support or report a correction?
Contact The Ship Doctor with your book title, page and case or question number. For a purchase query, include the email used at checkout. Read the sales and refund policy.
