Question

Based on the provided ECG description (Ventricular Tachycardia), which of the following statements is correct?

A) There are no discernible P waves, and the QRS complexes are wide and not applicable (n/a), indicating a regular and rapid ventricular rhythm at 150 beats per minute.

B) The P wave is absent, and there are narrow QRS complexes, indicating a potential atrial issue and a regular ventricular rhythm at 150 beats per minute.

C) The P wave is present, but there are wide QRS complexes, suggesting a normal atrial depolarization and a regular ventricular rhythm at 150 beats per minute.

D) Both P waves and QRS complexes are absent, indicating asystole, a condition of no cardiac electrical activity.

Answer 1

The correct statement for Ventricular Tachycardia on an ECG is that there are no discernible P waves, and the QRS complexes are wide, indicating a regular and rapid ventricular rhythm at 150 beats per minute.

Step-by-step explanation:

Based on the provided ECG description of Ventricular Tachycardia, the correct statement is A) There are no discernible P waves, and the QRS complexes are wide and not applicable (n/a), indicating a regular and rapid ventricular rhythm at 150 beats per minute. This is because Ventricular Tachycardia is characterized by the absence of discernible P waves, which represent atrial depolarization, and the presence of abnormal, wide QRS complexes due to the rapid depolarization of the ventricles originating from a ventricular ectopic focus, rather than the normal conduction pathway.
