Final answer:
The correct answer to the question is D) Sinus Rhythm with PVCs and VTach, as it describes a normal sinus rhythm interrupted by premature ventricular contractions and a short episode of ventricular tachycardia.
Step-by-step explanation:
The cardiac rhythm characterized by Sinus Rhythm with Premature Ventricular Contractions (PVCs) and a Triplet/run of Ventricular Tachycardia (VTach) is referred to in the question options as Sinus Rhythm with PVCs and VTach. This rhythm implies that the heart mainly beats with a normal sinus rhythm, but it is interrupted by premature ventricular contractions and occasionally, a rapid succession of VTach beats occurs. Analyzing the options provided, A) Atrial Fibrillation is characterized by an irregular atrial rhythm, B) Sinus Bradycardia is a slow heart rate in sinus rhythm, C) Ventricular Fibrillation is chaotic with no discernible QRS complexes, and D) Sinus Rhythm with PVCs and VTach accurately describes a normal sinus rhythm interspersed with premature ventricular contractions and a brief episode of ventricular tachycardia. Therefore, the correct answer is D) Sinus Rhythm with PVCs and VTach.
