Question

Prior to a cardioversion procedure for the treatment of atrial fibrillation, the respiratory therapist should synchronize the defibrillator to which of the following waves on the ECG?

A. P
B. S
C. R
D. T

Answer 1

The respiratory therapist should synchronize the defibrillator to the P wave on the ECG prior to a cardioversion procedure for the treatment of atrial fibrillation.

Step-by-step explanation:

Prior to a cardioversion procedure for the treatment of atrial fibrillation, the respiratory therapist should synchronize the defibrillator to the P wave on the ECG.

The P wave represents the depolarization and contraction of the atria as they pump blood into the ventricles. Synchronizing the defibrillator to the P wave ensures that the electrical shock is delivered at the appropriate time during the cardiac cycle.
