Correct Answer is C

Explanation

A. First-degree AV block is characterized by a prolonged PR interval but does not typically present with irregular palpitations or a pulse deficit.
B. Sinus tachycardia causes a rapid but regular rhythm, whereas atrial fibrillation is irregularly irregular.
C. Atrial fibrillation is the correct answer. It is characterized by an irregular heart rate, absence of distinct P waves on an ECG, and a pulse deficit due to ineffective atrial contractions leading to incomplete ventricular filling.
D. Sinus bradycardia presents as a slow, regular heart rate rather than a rapid, irregular rhythm with a pulse deficit.

A. R-R is irregular B. There are absent P waves C. PR interval greater than 0.20 seconds in duration. D. The PR interval gets longer then drops.

Correct Answer is C

Explanation

A. First-degree heart block has a regular R-R interval, meaning the rhythm is typically regular.
B. The presence of P waves is a distinguishing feature of first-degree heart block. Absent P waves are more characteristic of atrial fibrillation or junctional rhythms.
C. First-degree heart block is characterized by a prolonged PR interval greater than 0.20 seconds, but all impulses are still conducted to the ventricles.
D. A progressively lengthening PR interval followed by a dropped QRS complex is indicative of second-degree Mobitz Type I (Wenckebach) heart block, not first-degree heart block.
