If there are several tiny spikes in place of P waves on the ECG, the nurse recognizes the arrhythmia as:
a. premature ventricular contraction (PVC).
b. atrial flutter/fibrillation.
c. ventricular tachycardia (VT).
d. premature atrial contraction (PAC).
B
Atrial flutter /atrial fibrillation has many small ineffective contractions prior to the QRS complex. An abnormally shaped P wave appears on the ECG before the QRS wave in PAC. PVC is seen as an early beat without a P wave and with a wide QRS complex. VT is seen as three or more PVCs in a row with a ventricular rate of greater than 100 beats per minute.
