# MASTER ECG INTERPRETATION PROMPT Act as a senior cardiologist, ECG educator, and medical illustrator. Create a complete ECG interpretation course for MBBS interns, PharmD students, nursing students, emergency medicine trainees, and junior doctors. ## Goal Teach ECG interpretation from beginner to advanced level using a systematic approach with numerous labeled diagrams, ECG strips, clinical examples, mnemonics, tables, and image-based explanations. --- # SECTION 1: ECG BASICS Explain: * What an ECG is * Cardiac conduction system * SA node * AV node * Bundle of His * Right bundle branch * Left bundle branch * Purkinje fibers Include: * High-quality labeled anatomical images of the conduction system * Electrical impulse pathway diagrams * Heart anatomy diagrams showing lead perspectives --- # SECTION 2: ECG PAPER Create images showing: * ECG paper layout * Small box * Large box * Time calculation * Voltage calculation Explain: * 1 small square = ? * 1 large square = ? * 25 mm/sec * 50 mm/sec Provide visual examples. --- # SECTION 3: ECG LEADS Create labeled images showing: ## Limb Leads * Lead I * Lead II * Lead III ## Augmented Leads * aVR * aVL * aVF ## Chest Leads * V1 * V2 * V3 * V4 * V5 * V6 Include: * Electrode placement diagrams * Lead territory maps * Heart wall correlation diagrams --- # SECTION 4: NORMAL ECG Show a normal ECG strip image. Label: * P wave * PR interval * QRS complex * ST segment * T wave * QT interval * U wave Provide normal values in a table. --- # SECTION 5: STEPWISE ECG INTERPRETATION Create a visual flowchart: 1. Check calibration 2. Determine heart rate 3. Assess rhythm 4. Determine axis 5. Examine P waves 6. Measure PR interval 7. Evaluate QRS 8. Assess ST segment 9. Examine T waves 10. Calculate QTc 11. Clinical correlation Use image examples for every step. --- # SECTION 6: HEART RATE CALCULATION Create images demonstrating: * 300 method * 1500 method * 6-second method Provide worked examples. --- # SECTION 7: RHYTHM ANALYSIS Create ECG examples of: Normal sinus rhythm Sinus: * Bradycardia * Tachycardia * Arrhythmia Atrial: * PAC * Atrial flutter * Atrial fibrillation Junctional rhythms Ventricular rhythms Include side-by-side comparisons. --- # SECTION 8: CARDIAC AXIS Create: * Hexaxial reference system image * Axis wheel diagram Teach: * Normal axis * Left axis deviation * Right axis deviation * Extreme axis deviation Include ECG examples. --- # SECTION 9: CHAMBER ENLARGEMENT Create ECG images showing: Right atrial enlargement Left atrial enlargement Right ventricular hypertrophy Left ventricular hypertrophy Include diagnostic criteria and examples. --- # SECTION 10: AV BLOCKS Create ECG strips and diagrams for: First-degree AV block Second-degree AV block: * Mobitz I * Mobitz II Third-degree AV block Highlight key identifying features. --- # SECTION 11: BUNDLE BRANCH BLOCKS Create images and ECG examples of: Right bundle branch block (RBBB) Left bundle branch block (LBBB) Show: * Rabbit ears pattern * Wide QRS examples * Diagnostic criteria --- # SECTION 12: MYOCARDIAL INFARCTION Create ECG images for: Inferior MI Anterior MI Anteroseptal MI Lateral MI Posterior MI Right ventricular MI Include: * Coronary artery involvement * ECG territory maps * Reciprocal changes * STEMI vs NSTEMI comparison --- # SECTION 13: ST-T CHANGES Create examples of: Hyperkalemia Hypokalemia Hypercalcemia Hypocalcemia Pericarditis Myocarditis Early repolarization Digitalis effect --- # SECTION 14: EMERGENCY ECGs Create image examples of: Ventricular tachycardia Ventricular fibrillation Torsades de Pointes Asystole Pulseless electrical activity Supraventricular tachycardia Wolff-Parkinson-White syndrome Brugada syndrome Long QT syndrome Short QT syndrome --- # SECTION 15: PACEMAKER ECGs Create images showing: * Atrial pacing * Ventricular pacing * Dual chamber pacing Explain pacemaker spikes. --- # SECTION 16: ECG DIFFERENTIAL DIAGNOSIS TABLES Create comparison tables: AF vs Atrial Flutter SVT vs VT RBBB vs LBBB STEMI vs Pericarditis Hyperkalemia vs MI Mobitz I vs Mobitz II --- # SECTION 17: ECG INTERPRETATION CHEAT SHEET Create: * One-page summary * Quick reference table * Emergency diagnosis checklist * ECG pattern recognition guide --- # SECTION 18: CLINICAL CASES Provide 50 ECG case studies. For each case include: * ECG image * Patient history * Step-by-step interpretation * Final diagnosis * Clinical pearls --- # IMAGE REQUIREMENTS Generate: * High-resolution ECG strips * Annotated ECG diagrams * Colored conduction pathway diagrams * Lead placement photographs * Axis wheel illustrations * Infographics * Flowcharts * Tables * Mnemonic charts All images must be clearly labeled and suitable for medical education. --- # TEACHING STYLE Explain like an expert cardiology professor teaching a medical intern. For every ECG: 1. Show image 2. Explain findings 3. Give interpretation method 4. Mention common mistakes 5. Discuss clinical significance 6. Provide memory tricks Use simple language first, then advanced cardiology concepts.
