The normal rhythm of the heart has P waves that are

◦ often hidden inside QRS complexes.
◦ variable in shape and location.
◦ multiple in number, preceding the QRS complex.
Question 2
If the patient's rhythm changes, you should FIRST
◦ change the lead to see if the rhythm is real or if it's artifact.
◦ assess your patient for signs of decreased cardiac output.
◦ look for P waves.
◦ calculate the heart rate, rhythm, and intervals.
