Which condition does the patient have? - Complete left bundle branch block - Complete right bundle branch block - Incomplete left bundle branch block - Incomplete right bundle branch block ✓ (my answer) **4.** Identify the conduction defect associated with the ECG changes depicted below (12-lead tracing, left axis deviation pattern). - Left anterior fascicular block ✓ (my answer) - Left posterior fascicular block - Left septal fascicular block - None of the above **5.** Which condition is characterized by W-shaped QRS complex in right chest leads (V1 and V2)? - Left bundle branch block ✓ (my answer) - Right bundle branch block - Left anterior fascicular block - Left posterior fascicular block **6.** Which of the following accessory pathway is more commonly involved in the pathology of Wolf-Parkinson-White syndrome? - Bundle of Kent ✓ (my answer) - Bundle of Mahaim - Atrio-Hisian connection - Hisioventricular connection **7.** Which of the following condition can cause left atrial hypertrophy? - Cystic fibrosis - Pulmonary embolism - Tricuspid valve disease - Mitral valve insufficiencies ✓ (my answer) **8.** Which of the following reasons causes trifascicular block? - Delay in the intra-atrial conduction system - Transmission of impulse from AV node to bundle of His ✓ (my answer) - Rapid conduction in the right and left bundle branches - All of the above **9.** Which of the following findings can you find in the ECG tracings of a patient with left anterior fascicular block? - PR interval greater than 0.24 seconds - Left axis deviation usually greater than -45° ✓ (my answer) - Small initial negativity followed by deep negativity in QRS complex on lead II - All of the above **10.** The QT interval of a patient with syncope and palpitations is 0.36 sec. The RR interval is 0.52. What do you anticipate from these findings? - Patient has long QT syndrome ✓ (my answer) - Patient has short QT syndrome - Patient has Brugada type 1 syndrome - Patient has Brugada type 2 syndrome **11.** Upon reviewing the ECG tracings of a patient with conduction defect, the cardiologist interprets that the patient has left anterior fascicular block with inferior myocardial infarction. Which of these findings did the cardiologist notice in the patient's ECG? - q wave in lead II - Left axis deviation ✓ (my answer) - Peak of R wave in aVL occurs earlier than peak of R wave in aVR - All of the above **12.** What are the common causes of pseudomalfunction of pacemaker? - Changes in the pacing rate - Changes in the ECG morphology - Changes in the refractory period - All of the above ✓ (my answer) **13.** Which pacemaker malfunction results from inappropriate sensing of extraneous electrical signals? - Oversensing ✓ (my answer) - Undersensing - Failure to pace - Failure to capture **14.** In which of the following method impulses from an artificial pacemaker are delivered through the skin from an externally placed electrode pads? - Epicardiac method - Transvenous method - Transcutaneous method ✓ (my answer) - All of the above **15.** In which condition is the right ventricle activated first by the right bundle branch, then the interventricular septum is activated abnormally in a right-to-left direction, followed by left ventricular activation? - Left bundle branch block ✓ (my answer) - Right bundle branch block - Left anterior fascicular block - Left posterior fascicular block **16.** While assessing the ECG of a patient with artificial pacemaker, the cardiologist finds R-on-T phenomenon. Which pacemaker defect does the cardiologist anticipate in this patient? - Oversensing - Undersensing ✓ (my answer) - Failure to pace - Failure to capture **17.** Which of the following inherited cardiac arrhythmia is associated with QTc >0.46 and congenital deafness? - Brugada syndrome - Romano-Ward syndrome - Lange-Nielsen syndrome ✓ (my answer) - Catecholamine polymorphic ventricular tachycardia **18.** What is the code of a pacemaker, which senses and paces both atrial and ventricles, has multiple programmable parameters, and generates triggered impulses? - AVTP - DDTM ✓ (my answer) - VATM - DDDC Kindly check ans is correct or not
