Question

question 20 of 20 what is the rhythm? select your answer. normal sinus rhythm with pacs sinus bradycardia atrial fibrillation (afib) ventricular fibrillation (vfib)

Explanation:

1. Analyze the key features of the ECG rhythm strip:

• Normal Sinus Rhythm with PACs would show normal P - QRS - T complexes with occasional premature atrial contractions. Here, there are no such extra P waves.
• Sinus Bradycardia has regular P - QRS - T complexes with a rate less than 60 beats per minute. This strip does not show regular rhythm.
• Atrial Fibrillation (AFib) is characterized by irregularly irregular rhythm and absence of P waves, which is consistent with the given ECG strip. There are no distinct P waves and the R - R intervals are irregular.
• Ventricular Fibrillation (VFib) shows chaotic electrical activity with no discernible QRS complexes, which is not the case here.

Answer:

Atrial Fibrillation (AFib)
