Correct Answer is B

Explanation

A. While atrial fibrillation with a rapid ventricular response requires attention, it is not an immediate concern unless associated with symptoms such as chest pain, shortness of breath, or hemodynamic instability.
B. A heart rate of 50 in a patient with a newly inserted permanent pacemaker may indicate bradycardia, which could be a sign of pacemaker malfunction or lead dislodgement. This patient requires immediate assessment to rule out complications.
C. While recent implantable cardioverter-defibrillator (ICD) discharge warrants evaluation, the patient is currently in normal sinus rhythm with a heart rate of 68, suggesting stability. This patient's assessment can be prioritized after the patient with the pacemaker issue is seen.
D. A heart rate of 58 in a patient with chronic atrial fibrillation on beta-blocker therapy may not be immediately concerning if the patient is asymptomatic and hemodynamically stable. This patient can be assessed after addressing the more urgent pacemaker issue.

A. Ventricular tachycardia B. Bigeminy C. Ventricular fibrillation D. Trigeminy

Correct Answer is A

Explanation

A. Three or more consecutive premature ventricular contractions (PVCs) on an ECG tracing is indicative of ventricular tachycardia, a serious arrhythmia that requires prompt intervention.
B. Bigeminy refers to a pattern of every other beat being a PVC, not necessarily three or more consecutive PVCs.
C. Ventricular fibrillation is characterized by chaotic, disorganized ventricular activity on the ECG and is not defined by the presence of consecutive PVCs.
D. Trigeminy refers to a pattern of every third beat being a PVC, not necessarily three or more consecutive PVCs.
