CCT Domain 4: Performing Ambulatory Monitoring Welcome to your CCT Domain 4: Performing Ambulatory Monitoring 1. CCT: Performing Ambulatory Monitoring When analyzing a Holter monitor recording, what is the significance of identifying a Mobitz Type II second-degree AV block? It indicates a high risk of progression to third-degree AV block. It signifies improved cardiac function. It represents normal heart rhythm variation. It indicates an artifact caused by poor electrode placement. None 2. CCT: Performing Ambulatory Monitoring During ambulatory monitoring, a patient exhibits a pattern of grouped beating. This is most likely indicative of which of the following? Sinus arrhythmia Bigeminy Atrial fibrillation Ventricular tachycardia None 3. CCT: Performing Ambulatory Monitoring What is the primary concern when a patient undergoing Holter monitoring experiences episodes of ventricular tachycardia (VT)? VT may progress to ventricular fibrillation. It can indicate an electrolyte imbalance. VT is typically asymptomatic. It may necessitate a pacemaker implantation. None 4. CCT: Performing Ambulatory Monitoring In the context of ambulatory monitoring, what is the significance of a prolonged QT interval? It indicates an increased risk of torsades de pointes. It suggests a slow heart rate. It is a common finding and typically benign. It indicates an artifact and requires no further action. None 5. CCT: Performing Ambulatory Monitoring When a patient's ambulatory monitor shows a sudden loss of QRS complexes without a preceding change in heart rate or rhythm, what is the most likely cause? Lead displacement Sinus arrest Atrial fibrillation Ventricular fibrillation None 6. CCT: Performing Ambulatory Monitoring If a patient undergoing ambulatory ECG monitoring experiences syncope and the monitor captures a corresponding pause in cardiac activity, what is the most likely diagnosis? Atrial fibrillation Ventricular tachycardia Sinus node dysfunction Premature ventricular contractions None 7. CCT: Performing Ambulatory Monitoring In ambulatory monitoring, a rapid succession of non-sustained ventricular tachycardia (NSVT) episodes is most indicative of: Imminent myocardial infarction. Increased risk of sudden cardiac death. Benign ectopic activity. Immediate need for defibrillation. None 8. CCT: Performing Ambulatory Monitoring When a Holter monitor records a supraventricular tachycardia (SVT) with an abrupt start and stop, what is the most likely type of SVT? Atrial fibrillation Atrial flutter Paroxysmal SVT Sinus tachycardia None 9. CCT: Performing Ambulatory Monitoring In ambulatory monitoring, what does the presence of a delta wave in conjunction with a shortened PR interval suggest? Sinus bradycardia First-degree AV block Wolff-Parkinson-White syndrome Long QT syndrome None 10. CCT: Performing Ambulatory Monitoring What is the significance of capturing a 'r-on-T' phenomenon during ambulatory monitoring? It is a normal variant. It predicts an imminent sinus arrest. It increases the risk of ventricular fibrillation. It indicates digitalis toxicity. None 1 out of 10 Time is Up! Time's up
