The rhythm is often identified at the same time the rate is determined. The RR interval is used to determine ventricular rhythm and the PP interval to determine atrial rhythm. If the intervals are the same or nearly the same throughout the strip, the rhythm is called regular. If the intervals are different, the rhythm is called irregular.


The ECG must be analyzed in a systematic manner to determine the patient’s cardiac rhythm and to detect dysrhythmias and conduction disorders, as well as evidence of myocardial ischemia, injury, and infarction. Chart 27-2 is an example of a method that can be used to analyze the patient’s rhythm. Once the rhythm has been analyzed, the findings are compared with and matched to the ECG criteria for dysrhythmias to determine a diagnosis. It is important for the nurse to assess the patient to determine the physiologic effect of the dysrhythmia and to identify possible causes. Treatment of dysrhythmias is based on the etiology and the effect of the dysrhythmia, not on its presence alone.
