Please contact us for a complete test in case you are interested. 1 / 25 1. What does this ECG show? A. Sinus Bradycardia B. First degree AV block C. Long QT interval D. Short QT interval 2 / 25 2. What does this ECG demonstrate? A. Interventricular conduction defects B. Left bundle branch block C. Pacemaker D. Right bundle branch block 3 / 25 3. What is the ECG diagnosis? A. 2:1 AV Block B. Sinus Bradycardia C. Complete Heart Block D. Mobitz-II AV Block 4 / 25 4. 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 Anterior MI C. Acute Lateral MI D. Acute Inferior MI 5 / 25 5. What is the finding A. Sinus Arrhythmia B. Sinus Rhythm C. Sinus Block D. Sinus Tachycardia 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. Right Ventricular Infarction B. Pansystolic Murmur C. Acute pancreatitis D. Perforated Duodenal Ulcer 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 to consider in this ECG A. Do Thyroid Function Tests to exclude Hypothyroidism B. Do Chest x-ray to look for pericardial effusion C. If patient is obese, this ECG is normal for him D. Repeat ECG on standard calibrations 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. 8 / 25 8. A 64-years-old, male patient with diabetes, presented to the ER with chest pain and sweating. His cardiac biomarkers were found to be elevated. This is his ECG. What is the diagnosis? A. NSTEMI B. Acute Inferior MI C. Unstable Angina D. Digoxin toxicity 9 / 25 9. What does this ECG show? A. WPW syndrome – Type A B. Right Ventricular Hypertrophy C. Acute Posterior wall STEMI D. RBBB 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 10 / 25 10. What type of ECG rhythm is this? A. Normal Sinus Rhythm B. Atrial Ectopics C. Mobitz-II Block D. Junctional Ectopics 11 / 25 11. A young patient presented with chest pain aggravating in lying posture. ECG shows features of: A. NSTEMI B. Pericarditis C. Acute Anterior MI D. Acute Lateral wall MI 12 / 25 12. What is the rhythm abnormality in this ECG strip? A. Long QT interval B. No abnormality C. Wenckebach phenomenon D. Sinus Bradycardia 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. 13 / 25 13. What is the ECG diagnosis? A. Atrial Flutter with variable block B. Atrial Fibrillation with coarse fibrillatory waves C. Atrial Flutter D. Patient with Parkinsonian tremors 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. 14 / 25 14. This elderly male patient, a known case of IHD, presented with dizziness and syncope. What does this ECG reveal? A. Mobitz II AV Block B. Complete Heart Block C. Sick Sinus Syndrome D. Sinus Bradycardia 15 / 25 15. What is the finding here? A. Mobitz-II AV block B. Sinus arrest C. Complete heart block D. Sinus bradycardia 16 / 25 16. This is an ECG taken in a patient who was coded blue. What is the treatment of choice? A. Amiodarone B. IV Magnesium Sulphate C. Defibrillation D. Synchronized Cardioversion ECG shows VF which is a shockable rhythm during CPR. The treatment of choice is Defibrillation. 17 / 25 17. This ECG is showing A. AF B. AF with bradycardia C. Normal ECG 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. 18 / 25 18. Patient with severe chest pain and diaphoresis. What is this ECG suggestive of? A. Anterolateral MI B. Pericarditis C. Lateral MI D. Anterior MI 19 / 25 19. What abnormality is present in this ECG? A. Sinus Arrhythmia B. Atrial Ectopics C. Junctional Ectopics D. No abnormality 20 / 25 20. What is the ECG diagnosis A. Sinus Tachycardia B. Supraventricular Tachycardia C. Junctional Tachycardia D. Sinus Rhythm 21 / 25 21. What does this ECG show? A. Monomorphic Ventricular Tachycardia (VT) B. Polymorphic VT C. Accelerated Idioventricular Rhythm D. Ventricular Fibrillation (VF) The ECG shows Monomorphic VT with RBBB pattern and Extreme Axis 22 / 25 22. An elderly patient with dizziness and syncope has this ECG. What is the definitive treatment? A. Epinephrine B. Temporary Pacemaker C. Atropine D. Permanent Pacemaker 23 / 25 23. This 68-years-old patient, a known diabetic and IHD case, presented with syncope. What does the ECG show? A. Bifascicular Block B. Trifascicular Block C. Right Bundle Branch 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. 24 / 25 24. What is this ECG consistent with? A. Brugada syndrome B. Hypothermia C. Lateral wall MI D. RBBB The ECG shows J-wave or Osborn waves, more typically seen here in anterior leads. 25 / 25 25. 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 Lateral MI C. Acute Anterior MI D. Acute Inferior MI Explanation: The ECG reveal typical ST elevation in leads I, aVL with reciprocal ST changes in inferior leads.
