Please contact us for a complete test in case you are interested. 1 / 25 1. What does this ECG show? A. AF B. Sinus Tachycardia C. Atrial Flutter D. SVT 2 / 25 2. What type of ECG rhythm is this? A. Normal Sinus Rhythm B. Mobitz-II Block C. Atrial Ectopics D. Junctional Ectopics 3 / 25 3. This ECG is suggestive of A. Acute Anterior STEMI B. Normal ECG C. Hyperkalemia D. Left Ventricular Hypertrophy 4 / 25 4. What is the ECG diagnosis A. Supraventricular Tachycardia B. Sinus Rhythm C. Junctional Tachycardia D. Sinus Tachycardia 5 / 25 5. What is the ECG diagnosis in this patient with acute severe chest pain? A. Acute Inferior MI B. Acute Anteroinferior MI C. Acute Posteroinferior MI D. Acute Anterior MI The ECG leads show ST elevation in inferior leads as well as posterior leads (labelled manually here as V7 and V8) 6 / 25 6. A 53-years-old male patient, with a history of heavy smoking, presented to ER with central crushing chest pain. What is your diagnosis? A. Acute Inferior MI B. Acute Lateral MI C. Acute Anterior MI D. Acute Anterolateral MI Explanation: The ECG reveal typical ST elevation in leads I, aVL with reciprocal ST changes in inferior leads. 7 / 25 7. What is the ECG diagnosis? A. Patient with Parkinsonian tremors B. Atrial Flutter C. Atrial Fibrillation with coarse fibrillatory waves D. Atrial Flutter with variable block Explanation: This ECG shows sawtooth waves (flutter waves) in the majority of leads with irregularly placed QRS waves. Therefore it is suggestive of Atrial Flutter with variable block. Tremors will show abnormal baseline only in limb leads. 8 / 25 8. What to consider in this ECG A. If patient is obese, this ECG is normal for him B. Repeat ECG on standard calibrations C. Do Thyroid Function Tests to exclude Hypothyroidism D. Do Chest x-ray to look for pericardial effusion ECG show low amplitude waves. The ECG was taken at 0.5 mV. Standard calibration is 1 mV which is equal to 10 mm (10 small squares). Every ECG has an initial bar, as shown in fig with arrows, representing the voltage calibration of that ECG. 9 / 25 9. What does this ECG show? A. Short QT interval B. Long QT interval C. Sinus Bradycardia D. First degree AV block 10 / 25 10. A young patient presented syncope. What is the ECG suggestive of? A. Acute Anterior MI B. Early Repolarization C. RBBB D. Brugada Syndrome 11 / 25 11. What is the finding here? A. Sinus bradycardia B. Sinus arrest C. Mobitz-II AV block D. Complete heart block 12 / 25 12. This elderly male patient, a known case of IHD, presented with dizziness and syncope. What does this ECG reveal? A. Sinus Bradycardia B. Complete Heart Block C. Sick Sinus Syndrome D. Mobitz II AV Block 13 / 25 13. What is the finding A. Sinus Rhythm B. Sinus Block C. Sinus Arrhythmia D. Sinus Tachycardia 14 / 25 14. What is the ECG diagnosis? A. Sinus Bradycardia B. Idioventricular Rhythm C. LBBB D. Acute Anterior MI 15 / 25 15. What does this ECG demonstrate? A. Left bundle branch block B. Interventricular conduction defects C. Pacemaker D. Right bundle branch block 16 / 25 16. The ECG shows A. Sinus Bradycardia B. Prolonged QT interval C. Complete heart block D. Sinus rhythm 17 / 25 17. A 60-year-old female with severe epigastric pain presented to you. What else you will look for in this patient? A. Acute pancreatitis B. Perforated Duodenal Ulcer C. Pansystolic Murmur D. Right Ventricular Infarction Explanation: Inferior MI is caused due to involvement of the Right Coronary Artery in the majority of cases. Right ventricular infarction may be associated with inferior MI. Therefore do an ECG by placing V3 and V4 leads in the same intercostal positions of the chest but on the right side. These are called RV3 and RV4. If there is right ventricular infarction, there ECG will show STEMI in RV3 & RV4. 18 / 25 18. What does this ECG show? A. Torsades de pointes B. Monomorphic VT C. VF D. Polymorphic VT 19 / 25 19. What does this ECG show? A. Torsades de pointes B. AF with rapid & aberrant conduction C. Monomorphic VT D. VF 20 / 25 20. This is an ECG taken in a patient who was coded blue. What is the treatment of choice? A. IV Magnesium Sulphate B. Amiodarone C. Synchronized Cardioversion D. Defibrillation ECG shows VF which is a shockable rhythm during CPR. The treatment of choice is Defibrillation. 21 / 25 21. What does this ECG show? A. RBBB B. Right Ventricular Hypertrophy C. WPW syndrome – Type A D. Acute Posterior wall STEMI This ECG test your knowledge for causes of predominant R wave in lead V1. There are mainly 5 causes: RBBB (in emergency cases, this may indicate Pulmonary Embolism in an appropriate clinical context) Acute Posterior wall MI (Do not miss to look for it in patients with typical symptoms) Right Ventricular Hypertrophy (RVH) WPW syndrome – Type A Dextrocardia 22 / 25 22. Patient with severe chest pain and diaphoresis. What is this ECG suggestive of? A. Pericarditis B. Lateral MI C. Anterolateral MI D. Anterior MI 23 / 25 23. What is the positive finding in this ECG? A. Sinus Rhythm B. Atrial Ectopics C. Sinus Bradycardia D. First Degree AV Block 24 / 25 24. Elderly patient with IHD. ECG diagnosis? A. Sinus Arrhythmia B. Atrial Fibrillation C. Sick Sinus Syndrome D. Multifocal Atrial Ectopics 25 / 25 25. A 60-years-old female patient with diabetes presented to you with severe pain in the epigastric region and dizziness. ECG show these changes. What is your diagnosis? A. Acute Inferior MI B. Acute Anterior MI C. Acute Lateral MI D. Acute Posterior MI LinkedIn Facebook Twitter VKontakte Visit our FB page Restart Quiz Send Feedback Previous Post Rheumatology Next Post Endocrinology
