Editorial rigour, not editorial noise.

The Rhythm is an independent weekly cardiology research digest: five papers, one Cardiology Intelligence Briefing, every Monday. It exists because reading the primary literature properly takes hours most clinicians don't have — so we do that reading, verify it against the source, and hand you the part that changes practice.

Independence

The Rhythm is editorially independent. We have no commercial relationships with pharmaceutical or device companies, and no paper is included, excluded, or framed on the basis of who funds or manufactures it. Where a study is industry-sponsored, that's stated plainly alongside the findings.

How an issue is put together

Each week's briefing goes through the same fixed process before it reaches a subscriber's inbox:

• Discovery. We scan the week's output across NEJM, The Lancet, JAMA, JACC, European Heart Journal and the major cardiology congresses for anything with real clinical weight.
• Primary-source verification. Every paper is checked against its DOI and the original publication — not a press release or a secondary summary — before it's written up.
• Statistic-level sourcing. Every figure we cite is traced back to the paper it came from, with the hazard ratio, confidence interval and p-value included, not just a headline number.
• Safety alongside efficacy. Adverse events and safety data are reported next to the efficacy result, not omitted or buried.
• Impact rating. Every paper is rated Practice-changing, Guideline watch, or Emerging evidence, and that rating has to match what the write-up actually says — no upgrading a result to sound more important than the data support.
• Language discipline. We don't use hedge phrases like "numerically higher," "trends toward," or "confirms" to make a marginal or non-significant result sound stronger than it is.

Who it's for

The Rhythm is written for cardiologists, cardiology trainees, and cardiovascular clinicians who want to stay current on the literature without spending hours in journals every week. Summaries are for informational purposes only and don't constitute medical advice — every reader is expected to exercise their own clinical judgement.
