Question

question 13 of 20 what is the rhythm? select your answer. sinus bradycardia atrial flutter with unifocal pvcs sinus tachycardia with multifocal pvcs sinus rhythm with unifocal pvcs

Explanation:

1. Observe the P - waves: In sinus rhythm, P - waves are regular and precede each QRS complex. Here, P - waves are present before each QRS and are of similar morphology, indicating a sinus origin.
2. Check for PVCs: Premature ventricular contractions (PVCs) are wide and bizarre - shaped QRS complexes. In the given ECG, there are occasional wide and abnormal QRS complexes which are unifocal (of the same shape), indicating unifocal PVCs.
3. Heart rate: The heart rate is within a normal range for sinus rhythm (not bradycardia or tachycardia).

Answer:

D. Sinus Rhythm with Unifocal PVC's
