How to Revise Cardiology for MRCP Part 1 | Crack Medicine

TL;DR

Cardiology is one of the most heavily tested specialties in MRCP Part 1, and revising it requires both conceptual clarity and systematic practice. If you’re wondering how to revise cardiology for MRCP Part 1, focus on ECG interpretation, valvular diseases, pharmacology, and heart failure management. A structured 6–8-week plan with regular mock tests, revision cycles, and Crack Medicine’s QBank can dramatically boost your score.


Why Cardiology Matters in MRCP Part 1

Cardiology integrates physiology, pharmacology, and clinical reasoning — making it both high-yield and conceptually dense. Roughly 15–20% of MRCP Part 1 questions are cardiovascular. Candidates often lose marks not from lack of knowledge but due to subtle interpretation errors, especially in ECGs, murmurs, or heart failure management algorithms.

A sound revision plan focuses on core mechanisms and pattern recognition rather than memorising isolated facts. At Crack Medicine, our curated QBank and recorded lectures emphasise these patterns — helping you think like an MRCP examiner, not just a candidate.


Step-by-Step Guide: How to Revise Cardiology for MRCP Part 1

1. Understand the Blueprint

The MRCP(UK) Part 1 Examination Blueprint identifies cardiovascular medicine as one of the highest-weighted domains. Within this, the focus is on:

  • Ischaemic heart disease and ACS

  • Arrhythmias and conduction disorders

  • Valvular heart disease

  • Heart failure and cardiomyopathies

  • Hypertension, pericardial, and congenital conditions

Don’t skip cross-system overlap — Cardiology questions often link to Renal (hypertension, oedema) and Endocrine (thyrotoxic heart disease).


2. Plan Your 6–8-Week Rotation

Week

Focus Area

Study Actions

1–2

Ischaemic heart disease, ECG basics

Review coronary anatomy and practise 100 ECGs

3–4

Arrhythmias, Valvular Disease

Learn murmur timing, echo findings, and drugs

5

Heart Failure, Cardiomyopathy

Compare systolic vs diastolic HF, read NICE NG106

6

Hypertension, Pericardial Disease

Study JVP waveforms, tamponade, and BP management

7–8

Full Mock Integration

Attempt 300 mixed questions + 2 timed mock tests

📘 Use Crack Medicine’s Free MRCP MCQs to track progress and build speed during these final weeks.

3. Focus on These 10 High-Yield Areas

  1. ST-segment localisation: Always relate ECG changes to coronary territories.

  2. Valvular timing: Systolic = AS/MR; Diastolic = MS/AR.

  3. Heart failure pharmacology: ACEi, β-blockers, ARNI improve mortality.

  4. Atrial fibrillation: Know CHA₂DS₂-VASc and rate vs rhythm strategies.

  5. Hypertension: Follow NICE NG136 stepwise therapy.

  6. Cardiomyopathies: Understand HOCM murmur changes with Valsalva.

  7. Pericarditis vs STEMI: Concave ST elevation + PR depression = pericarditis.

  8. Drug-induced arrhythmias: Digoxin, amiodarone, sotalol — common traps.

  9. Syncope causes: Cardiac vs neurocardiogenic — pattern recognition.

  10. Congenital shunts: Eisenmenger’s syndrome = reversal from L→R to R→L.

4. Reinforce With Question Practice

Repetition consolidates recall. Aim for at least 1,000 timed QBank questions, ideally 30–50 per day.

  • Mix cardiology with renal and endocrine to mimic real exam integration.

  • Review every wrong answer with explanations — the “why not” matters more than the “why.”

  • Track analytics in the Crack Medicine app to visualise performance trends and weak topics.

Note: The Crack Medicine app adds new mocks monthly and provides performance analytics for every system, helping you fine-tune your final-month revision.

5. Practice Example

Question: A 58-year-old woman presents with dyspnoea and orthopnoea. ECG shows atrial fibrillation with a controlled ventricular rate. Echocardiogram: left atrial enlargement, normal LV function, and a diastolic murmur at the apex. What is the most likely diagnosis?

Options: A. Aortic stenosisB. Mitral stenosisC. Mitral regurgitationD. Aortic regurgitation

✅ Answer: B. Mitral stenosis Explanation: Diastolic murmur + AF + LA enlargement → classical rheumatic mitral stenosis. The atrial stretch predisposes to AF.


Common Pitfalls (and Fixes)

  • ❌ Confusing STEMI vs pericarditis ECG patterns → ✅ Review pericarditis features weekly.

  • ❌ Over-revising rare syndromes (e.g., Brugada) → ✅ Prioritise ischaemic, valvular, HF topics.

  • ❌ Neglecting hypertension and drug contraindications → ✅ Learn NICE algorithms cold.

  • ❌ Memorising murmurs mechanically → ✅ Associate each with underlying pathophysiology.

  • ❌ Ignoring timing → ✅ Practise 90-second question pacing regularly.


Rapid-Fire Study Checklist

  1. Watch one cardiology lecture daily from Crack Medicine YouTube.

  2. Use flashcards for murmur differentials and drug mechanisms.

  3. Practise 3–5 ECGs each day using mock explanations.

  4. Take a weekly mock test under timed conditions.

  5. Review 10 wrong answers daily — spaced repetition boosts long-term recall.


FAQs

1. How long should I spend on Cardiology for MRCP Part 1?About 6–8 weeks, with daily ECG practice and weekly mocks. Don’t exceed two hours per day without question review.

2. What are the most commonly tested cardiology topics?

Ischaemic heart disease, valvular lesions, arrhythmias, hypertension, and heart failure.

3. What’s the best way to master ECGs?

Use a structured “rate–rhythm–axis–interval–ST/T” approach and practise using real ECG cases.

4. Which resources are reliable?

The official MRCP(UK) site, NICE guidelines, and Crack Medicine’s curated QBank.

5. How can I avoid silly mistakes in the exam?

Time yourself, eliminate clearly wrong options, and focus on the clinical clue hidden in each stem.
