Question

question 12 of 20 what is the rhythm? select your answer. supraventricular tachycardia (svt) atrial fibrillation (afib) sinus tachycardia normal sinus rhythm with pacs

Explanation:

1. Supraventricular Tachycardia (SVT) typically has a regular, narrow - complex rhythm at a rapid rate. This ECG does not show a consistently rapid and regular narrow - complex pattern.
2. Atrial Fibrillation (AFib) is characterized by an irregularly irregular rhythm with no discernible P waves. This ECG has some regular intervals and visible P - like waves, so it is not AFib.
3. Sinus Tachycardia has a regular rhythm with normal P waves and a rate usually between 100 - 180 beats per minute. The rate in this ECG is not consistently elevated to the level of tachycardia.
4. The ECG shows normal sinus - like P waves with some premature atrial contractions (PACs), which are early P waves that may have a different morphology. This is consistent with Normal Sinus Rhythm with PACs.

Answer:

Normal Sinus Rhythm with PAC's
