A "P mitrale" pattern on an EKG, characterized by a notched P wave in lead II with a duration >0.12 sec, suggests: a) Right Atrial Enlargement b) Left Atrial Enlargement c) Right Ventricular Hypertrophy d) Left Ventricular Hypertrophy ANSWER: b) Left Atrial Enlargement 11. A patient has a regular rhythm with a rate of 40 bpm. P waves are present and normal, each followed by a QRS complex. The PR interval is constant at 0.22 seconds. This is: a) Normal Sinus Rhythm b) Sinus Bradycardia with First-Degree AV Block c) Junctional Rhythm d) Complete Heart Block ANSWER: b) Sinus Bradycardia with First-Degree AV Block 12. Tall, peaked T waves are a classic early sign of: a) Hypokalemia b) Hyperkalemia c) Hypocalcemia d) Hypercalcemia ANSWER: b) Hyperkalemia 13. In a Right Bundle Branch Block (RBBB), the characteristic wide QRS often has what morphology in lead V1? a) Deep QS wave b) "W" or "RSR'" pattern c) Dominant R wave d) "QR" pattern ANSWER: b) "W" or "RSR'" pattern 14. The EKG shows a regular wide-complex tachycardia at a rate of 180 bpm. There is AV dissociation, with P waves marching through the QRS complexes. This is most diagnostic of: a) Supraventricular Tachycardia with Aberrancy b) Atrial Flutter with 2:1 block c) Ventricular Tachycardia d) Sinus Tachycardia ANSWER: c) Ventricular Tachycardia 15. The QT interval should be corrected for heart rate. The corrected QT (QTc) is considered prolonged if it is greater than: a) 0.34 seconds b) 0.44 seconds c) 0.47 seconds d) 0.50 seconds ANSWER: c) 0.47 seconds (for men; often >0.48 for women, but 0.47 is a commonly used critical threshold) 16. A "J point" is defined as: a) The start of the P wave b) The point where the QRS complex ends and the ST segment begins c) The peak of the T wave d) The end of the T wave ANSWER: b) The point where the QRS complex ends and the ST segment begins 17.

The most likely pacemaker site is: a) The SA node b) The Atria c) The AV Junction d) The Ventricles ANSWER: c) The AV Junction 19. The EKG shows a pattern of grouped beating: a normal beat, followed by a beat with a progressively longer PR interval, then a dropped QRS complex. This cycle repeats. This is: a) First-Degree AV Block b) Second-Degree AV Block, Type I (Wenckebach) c) Second-Degree AV Block, Type II d) Third-Degree AV Block ANSWER: b) Second-Degree AV Block, Type I (Wenckebach) 20.
