Answers and a brief explanation are provided.  \nQuestion 1  \nThis ECG rhythm is called:  \na) Sinus bradycardia changing to ventricular tachycardia  \nb) Junctional rhythm with a run of ventricular tachycardia  \nc) Sinus rhythm terminating in ventricular fibrillation  \nd) Sinus bradycardia changing to junctional tachycardia  \nAnswer: a) Sinus bradycardia changing to ventricular tachycardia  \nExplanation: The ECG rhythm strip begins with a sinus bradycardia: a series of narrow QRS complexes, upright P waves and a rate of about 56/minute. A wide and premature QRS (premature ventricular complex) begins a rapid, regular series of wide QRS complexes that are most likely ventricular tachycardia. The deep Q waves might indicate a previous myocardial infarction.  \nQuestion 2  \nThis ECG rhythm is called:  \na) Sinus rhythm with multifocal premature ventricular complexes (PVCs)  \nb) Sinus bradycardia with ventricular paced beats  \nc) Sinus rhythm with paced ventricular beats  \nd) Junctional rhythm with unifocal PVCs  \nAnswer: c) Sinus rhythm with ventricular paced beats  \nExplanation: The underlying rhythm is a sinus rhythm: narrow QRS, upright P waves and a rate of about 75/minute. The two wide QRS complexes are preceded by the small spike which strongly suggests that these are initiated by an electronic ventricular pacemaker. Note also that the ventricular complexes are not early (premature) but rather arrive late with the electronic pacemaker probably set in demand mode with a rate of 60/minute.  \nSix Second ECG Quiz 1B v1.2 Annotated Answer Key  \nQuestion 3  \nThis ECG rhythm is called:  \na) Junctional rhythm with a premature atrial complex (PAC)  \nb) Sinus bradycardia with a premature atrial complex (PAC)  \nc) Sinus arrhythmia  \nd) Sinus rhythm with a PVC  \nAnswer: b) Sinus bradycardia with a premature atrial complex (PAC)  \nExplanation: The underlying rhythm is a sinus bradycardia with narrow QRS complexes, upright P waves and a rate of about 50/minute. A premature atrial complex (PAC) is the third QRS present (a narrow QRS complex arriving prematurely and accompanied by a biphasic P wave) .  \nQuestion 4  \nThis ECG rhythm is called:  \na) Sinus tachycardia with a PVC  \nb) Atrial fibrillation with rapid ventricular response  \nc) Sinus tachycardia with a PAC  \nd) Sinus arrhythmia with a PAC  \nAnswer: c) Sinus tachycardia with a premature atrial complex (PAC)  \nExplanation: The underlying rhythm is a sinus tachycardia with narrow QRS complexes, upright P waves and a rate of about 110/minute. A premature atrial complex (PAC) is the sixth QRS present (a narrow QRS complex arriving prematurely and accompanied by a biphasic or otherwise abnormally shaped P wave-an absent or an inverted P wave suggests a PJC) .  \nNote that the T wave prior to the premature QRS complex is more elevated than the other T waves. This finding supports the possible presence of an upright P wave buried in the T wave. Since a PJC is accompanied by absent or inverted P waves (which when buried in a T wave would not change the T wave, decrease the size ofthe T wave or produce an inverted notch in the T wave), this premature supraventricular complex is most likely a PAC.  \nQuestion 5  \nThis ECG rhythm is called:  \na) Sinus arrhythmia  \nb) Junctional tachycardia  \nc) Ventricular tachycardia  \nd) Sinus tachycardia  \nAnswer: d) Sinus tachycardia  \nExplanation: With a rate of about 104/minute and a narrow QRS complex, this is a tachycardia of supraventricular origin. The upright P waves with a heart rate less than 150/minute strongly point to the sino-atrial node as the site of impulse generation. The best answer is that this rhythm is a sinus tachycardia.  \n","cbCaicL2EkEpVkoP","https://ap.wps.com/l/cbCaicL2EkEpVkoP","pdf",476922,"English","# Question 1\n# Question 2\n# Question 3\n# Question 4\n# Question 5\n# Question 6\n# Question 7\n# Question 8\n# Question 9","[{\"question\":\"What kind of document is the Six Second ECG Quiz 1B annotated answer key used for?\",\"answer\":\"It serves as a reference for ECG instructors and students.
