Health information you can follow, and check.

Clear, sourced guides to conditions, tests, treatments and procedures in the UK, written in plain English and structured the way a clinician would explain them.

A calm consulting room
Why Pulse Atlas

An independent health library, with the sources on the page.

Every guide shows where its information comes from, when it was last reviewed, and what it means in practice for someone in the UK.

  • Sourced

    Every guide cites the NHS, NICE, the royal colleges and specialist charities, with the sources shown on the page.

  • Plain English

    Medical terms are explained where they appear, so you do not need a clinical background to follow the page.

  • UK-specific

    NHS and private pathways, UK units and UK guidance, rather than material adapted from elsewhere.

  • Reviewed and dated

    Each page shows who reviewed it and when, and is updated on a published review schedule.

For understanding, and for preparing for a conversation with your clinician - not a substitute for one.

Patient resources

A clinical reference, written for patients.

Every guide is written by our editorial team from named UK sources, and shows when it was last reviewed.
