Question

question 18 of 20 what is the rhythm? select your answer. sinus rhythm with a 1st degree av nodal block sinus rhythm with 3rd degree (complete) av block atrial flutter sinus bradycardia

Explanation:

Sinus bradycardia is characterized by a regular rhythm with a heart - rate less than 60 beats per minute. In the given ECG, the P - waves are regular, the PR intervals are normal, and the rate is slow, which is consistent with sinus bradycardia. In sinus rhythm with 1st degree AV nodal block, there would be a prolonged PR interval. In 3rd degree AV block, there is no relationship between P - waves and QRS complexes. Atrial flutter shows characteristic saw - toothed flutter waves.

Answer:

Sinus Bradycardia
