Please contact us for a complete test in case you are interested. 1 / 25 1. Patient with severe chest pain and diaphoresis. What is this ECG suggestive of? A. Anterior MI B. Anterolateral MI C. Pericarditis D. Lateral MI 2 / 25 2. This 68-years-old patient, a known diabetic and IHD case, presented with syncope. What does the ECG show? A. Bifascicular Block B. Right Bundle Branch Block C. Trifascicular Block D. First Degree AV Block The ECH shows RBBB, LAD and First degree AV block. This is trifascicular block and is equivalent to a complete heart block. The treatment of choice is Pacemaker. 3 / 25 3. Elderly patient with IHD. ECG diagnosis? A. Atrial Fibrillation B. Sinus Arrhythmia C. Multifocal Atrial Ectopics D. Sick Sinus Syndrome 4 / 25 4. What is the ECG diagnosis? A. Acute Anterior MI B. Sinus Bradycardia C. LBBB D. Idioventricular Rhythm 5 / 25 5. 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 Anterolateral MI B. Acute Inferior MI C. Acute Anterior MI D. Acute Lateral MI Explanation: The ECG reveal typical ST elevation in leads I, aVL with reciprocal ST changes in inferior leads. 6 / 25 6. A 60-year-old female with severe epigastric pain presented to you. What else you will look for in this patient? A. Pansystolic Murmur B. Acute pancreatitis C. Perforated Duodenal Ulcer 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. 7 / 25 7. What abnormality is present in this ECG? A. Sinus Arrhythmia B. Atrial Ectopics C. Junctional Ectopics D. No abnormality 8 / 25 8. The ECG was done on a patient with vomiting & diarrhoea, complaining of lethargy. What is your ECG diagnosis? A. AF B. Hypokalemia C. Long QT syndrome D. Atrial Flutter 9 / 25 9. What is the ECG diagnosis in this patient with acute severe chest pain? A. Acute Anteroinferior MI B. Acute Inferior 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) 10 / 25 10. What does this ECG show? A. Ventricular Fibrillation (VF) B. Polymorphic VT C. Monomorphic Ventricular Tachycardia (VT) D. Accelerated Idioventricular Rhythm The ECG shows Monomorphic VT with RBBB pattern and Extreme Axis 11 / 25 11. What is the ECG diagnosis? A. SVT B. Sinus Tachycardia C. AF D. Multifocal atrial tachycardia 12 / 25 12. What does this ECG showing A. LVH B. Sinus arrhythmia C. Normal D. Bradycardia 13 / 25 13. This elderly male patient, a known case of IHD, presented with dizziness and syncope. What does this ECG reveal? A. Sinus Bradycardia B. Sick Sinus Syndrome C. Mobitz II AV Block D. Complete Heart Block 14 / 25 14. This ECG is suggestive of A. Normal ECG B. Left Ventricular Hypertrophy C. Acute Anterior STEMI D. Hyperkalemia 15 / 25 15. This ECG was taken in a patient with DVT and acute chest pain with shortness of breath. What is the possible diagnosis? A. Pulmonary Embolism B. NSTEMI C. Acute Anterior MI (new RBBB) D. Unstable Angina The ECG shows typical S1Q3T3 changes, Right axis deviation and RBBB. 16 / 25 16. 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 Posterior MI B. Acute Inferior MI C. Acute Anterior MI D. Acute Lateral MI 17 / 25 17. What is the rhythm abnormality in this ECG strip? A. Wenckebach phenomenon B. Sinus Bradycardia C. No abnormality D. Long QT interval Explanation: The ECG strip shows gradual prolongation of the PR interval followed by a non-conducted P wave. This is Wenckebach Phenomenon or Second degree, Mobitz-I AV Block. 18 / 25 18. Comment what is the cardiac axis in this ECG? A. Right Axis Deviation (RAD) B. Left Axis Deviation (LAD) C. Extreme axis D. Normal axis 19 / 25 19. What does this ECG show? A. Polymorphic VT B. VF C. Monomorphic VT D. Torsades de pointes 20 / 25 20. What to consider in this ECG A. Do Thyroid Function Tests to exclude Hypothyroidism B. If patient is obese, this ECG is normal for him C. Repeat ECG on standard calibrations 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. 21 / 25 21. What is the ECG diagnosis? A. Mobitz-II AV Block B. Complete Heart Block C. 2:1 AV Block D. Sinus Bradycardia 22 / 25 22. What does this ECG show? A. Short QT interval B. First degree AV block C. Long QT interval D. Sinus Bradycardia 23 / 25 23. What does this ECG show? A. AF B. SVT C. Sinus Tachycardia D. Atrial Flutter 24 / 25 24. This ECG is showing A. Normal ECG B. AF C. AF with bradycardia D. Atrial flutter Apparently, there are fibrillation waves, however by looking closely on ECG, QRS complexes are preceded by P waves, Heart rate is around 60 so no bradycardia. 25 / 25 25. What is the ECG diagnosis? A. Atrial Flutter with variable block B. Atrial Fibrillation with coarse fibrillatory waves C. Patient with Parkinsonian tremors D. Atrial Flutter 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. LinkedIn Facebook Twitter VKontakte Visit our FB page Restart Quiz Send Feedback Previous Post Rheumatology Next Post Endocrinology
