1) Sinus rhythm is regular, with P, QRS, and T deflections and normal intervals. Heart rate = 60-100 bpm. a) True b) false 2) What is ? a) Sinus bradycardia is a sinus rhythm with a rate higher than 60 beats per minute in an adult. b) Sinus bradycardia is a sinus rhythm with a rate of less than 60 beats per minute in an adult. c) atrial fibrillation d) flutter 3) What is the name of this electrocardiogram? a) Sinus Rhythm b) Sinus Bradycardia c) Sinus Tachycardia d) atrial fibrillation 4) Second-Degree AV Heart Block is ? a) is regular with normal P, Q-R-S, T deflections and intervals. Rate = 60-100 at rest. b) is characterized by bizarre widened QRS complexes, no P waves and usually a rate over 100 per minute. May quickly degenerate to Ventricular fibrillation and death. VT may be responsive to electrical defibrillation. c) AV block is usually classified as Mobitz Type I (Wenckebach) or Mobitz Type II. A Mobitz Type I heart block is characterized by progressive lengthening of the PR interval until a QRS complex is dropped. 5) Third-Degree Heart Block is ? a) b) 6) Supraventricular Tachycardia is ? a) b) c) 7) First-Degree Heart Block ? a) true b) false 8) Atrial Fibrillation ? a) true b) false 9) What is the name of this electrocardiogram ? a) Asystole b) Supraventricular Tachycardia c) Atrial Flutter 10) Ventricular Tachycardia is ? a) is characterized by bizarre widened QRS complexes, no P waves and usually a rate over 100 per minute. May quickly degenerate to Ventricular fibrillation and death. VT may be responsive to electrical defibrillation. b) is a supraventricular arrhythmia that is characterized by a “saw-toothed” flutter appearance on the ECG that represents multiple P waves for each QRS complex. 11) Pulseless Electrical Activity a) true b) false 12) First-Degree Heart Block IS ? a) with a prolonged PR interval > 0.20 seconds due to a delay in transmission from the atria to the ventricles. b) with a prolonged PR interval < 0.20 seconds due to a delay in transmission from the atria to the ventricles. c) with a prolonged PR interval > 0.30 seconds due to a delay in transmission from the atria to the ventricles. d) with a prolonged PR interval > 0.10 seconds due to a delay in transmission from the atria to the ventricles. 13) What is a sinus rhythm a) b) c) d) 14) The correct answer is? a) Sinus tachycardia is a sinus rhythm with a rate greater than 100 per minute in an adult. Note that the p waves are still present. b) Sinus tachycardia is a sinus rhythm with a rate greater than 60 per minute in an adult. Note that the p waves are still present. c) Sinus tachycardia is a sinus rhythm with a rate greater than 200 per minute in an adult. Note that the p waves are still present. d) Sinus tachycardia is a sinus rhythm with a rate greater than 70 per minute in an adult. Note that the p waves are still present. 15) The correct answer is? a) The p wave corresponds to a repolarization of the ventricles. b) The T wave corresponds to a repolarization of the ventricles. c) The QRS wave corresponds to a repolarization of the ventricles. d) The U wave corresponds to a repolarization of the ventricles. 16) The correct answer is? a) The T wave corresponds to electrical impulse traveling through the atria. This is synonymous with atrial depolarization and usually corresponds with atrial contraction. b) The R wave corresponds to electrical impulse traveling through the atria. This is synonymous with atrial depolarization and usually corresponds with atrial contraction. c) The Q wave corresponds to electrical impulse traveling through the atria. This is synonymous with atrial depolarization and usually corresponds with atrial contraction. d) The P wave corresponds to electrical impulse traveling through the atria. This is synonymous with atrial depolarization and usually corresponds with atrial contraction. 17) ventricular fibrillation is not characterized by a chaotic Wave pattern and no pulse a) true b) false 18) Atrial flutter is a supraventricular arrhythmia that is characterized by ? a) flat line b) no pulse c) saw- toothed d) < 0.20 seconds 19) regular with normal P,Q-R-S,T deflections and intervals. Rate = 60-100 at rest a) sinus bradycardia b) sinus tachycardi c) sinus rhythm d) atrial fibrillation 20) atrial fibrillation is a very como arrhythmia. This rhythm is characterized by no sabes before the QRS complex and a very irregular heart rate. a) false b) true
