Question

You are examining an ECG from your patient and you see rapid, irregular, uncoordinated depolarizations of the atria and no definite P waves. Your patient is likely suffering from ________ .

1) ventricular fibrillation
2) heart attack
3) complete heart block
4) atrial fibrillation
5) atrial flutter

Answer 1

The patient whose ECG shows rapid, irregular, and uncoordinated atrial depolarizations without definite P waves is likely suffering from atrial fibrillation.

Step-by-step explanation:

If you're examining an ECG and observe rapid, irregular, uncoordinated depolarizations of the atria without definite P waves, your patient is likely suffering from atrial fibrillation. According to the reference information, atrial fibrillation is characterized by an abnormal electrical pattern before the QRS complex and an increased frequency between the QRS complexes. This aligns with the description given in the question, as atrial fibrillation involves the atria beating in a rapid, irregular, and uncoordinated manner which can lead to a lack of distinct P waves on the ECG.
